Introduction

The Phantom 4 RTK is a smart mapping and imaging drone capable of highly accurate mapping functions. The aircraft has a built-in DJI Onboard D-RTKTM, which provides precision data for centimeter-level positioning accuracy*. Multi-directional obstacle sensing achieved through vision and infrared sensors enables intelligent obstacle avoidance during flight and indoor hovering and flight. The Phantom 4 RTK records videos at 4K and captures 20 megapixel photos. The OCUSYNCTM HD video downlink built into both the aircraft and remote controller ensures a reliable and stable transmission.

Features Highlights

The Phantom 4 RTK aircraft has a built-in DJI Onboard D-RTK, providing high-precision data for centimeterlevel positioning when used with Network RTK service or a DJI D-RTK 2. Raw satellite observations and

exposure event records can be used for post-processed kinematic (PPK) dierential corrections.

The Phantom 4 RTK can hover and y in extremely low altitude and indoor environments, and provides

multi-directional obstacle sensing and vision positioning functions. Obstacles detection and avoidance in

large range and landing protection enhance ight safety.

The Phantom 4 RTK is equipped with a 24 mm (35 mm format equivalent) wide angle camera, high-

precision and anti-shake gimbal, 1-inch CMOS sensor, mechanical shutter to oer the best in aerial photo

analysis.

Built into the remote controller is the latest DJI OcuSync technology with enhanced anti-interference capability to deliver a more stable and smoother video downlink. When combined with the receiver in the aircraft, the remote controller has a transmission range up to 4.3 mi / 7 km (FCC-compliant version). The remote controller is equipped with a 5.5-inch high luminance monitor, and an integrated DJI GS RTK App

for real-time HD display. Users can plan ight paths and perform ight operations in the app for operation

types of Photogrammetry, Waypoint Flight, Linear Flight, Terrain Awareness Mode, and Block Segmentation. For Photogrammetry, Linear Flight, Terrain Awareness Mode, and Block Segmentation operations, simply

tap on the map in the app or import les to set a ight area. For waypoint operations, y the aircraft to set waypoints and congure waypoint actions, then the aircraft will be able to perform automated operations.

The remote controller’s Multi-Aircraft Control mode can be used to coordinate the operation of up to ve aircraft at the same time, enabling pilots to work very eciently. Image data from the Phantom 4 RTK can be used to generate maps for eld planning when operating a DJI

AGRASTM aircraft. Users can also import photos to the DJI PC GS Pro application or third-party mapping

software to composite highly accurate maps for dierent applications.

Aircraft

This section introduces the aircraft components, features and functions.

Aircraft

Profile

The Phantom 4 RTK aircraft includes a flight controller, a communication system, a positioning system, a propulsion system and an Intelligent Flight Battery. This section describes the functions of these components.

Flight Modes

The Phantom 4 RTK uses a DJI dedicated ight controller, which provides the ight modes below:

P-mode (Positioning): P-mode works best when the GNSS signal is strong. The aircraft utilizes the GNSS / RTK module and Vision System to automatically stabilize itself, navigate between obstacles, and perform a Photogrammetry or Waypoint Flight operation.

When the GNSS signal is strong, the aircraft uses GNSS for positioning. When RTK module is enabled and

the dierential data transmission is good, it provides centimeter-level positioning. When the GNSS signal is weak and the lighting conditions are sucient, the aircraft uses Vision System for positioning.

When the forward obstacle sensing is enabled and lighting conditions are sucient, the maximum ight attitude angle is 25° with a maximum ight speed of 31 mph (50 kph). When forward obstacle sensing is disabled, the maximum ight attitude angle is 35° and the maximum ight speed is 36 mph (58 kph).

A-mode (Attitude): GNSS and Vision System are NOT used for positioning and aircraft can only maintain altitude using the barometer. It enters A-mode only when there is weak GNSS signal or when the compass experiences interference where the Vision System is unavailable.

Attitude Mode Warning

The aircraft will y in P-mode by default. It enters A-mode only when there is weak GNSS signal or when the

compass experiences interference where the Vision System is unavailable.

In A-mode, the Vision System and some advanced features are disabled. Therefore, the aircraft cannot

position or auto-brake in this mode and is easily aected by its surroundings, which may result in horizontal

shifting. Use the remote controller to position the aircraft.

Maneuvering the aircraft in A-mode can be dicult. Avoid ying in areas where GNSS signal is weak, or in conned spaces. The aircraft will otherwise be forced to enter A-mode, leading to potential ight risks,

please land it in a safe place as soon as possible.

Return to Home (RTH)

Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes these three scenarios in detail.

GNSS

If a strong GNSS signal was acquired before takeo, the Home Point is the location

Home Point

The aircraft can sense and avoid obstacles when the Forward Vision System is enabled and lighting conditions are sufficient. The aircraft will automatically climb up to avoid obstacles and descend slowly as it returns to the Home Point. To ensure the aircraft returns home forwards, it cannot rotate

or y left and right during RTH while the Forward Vision System is enabled.

from which the aircraft launched. The GNSS signal strength is indicated by the GNSS icon ( Less than 4 bars is considered a weak GNSS signal). The aircraft status indicators will blink rapidly when the home point is recorded.

Description

Updating the Home Point

You can update the Home Point in the DJI GS RTK app during ight. There are two options for setting the Home

Point:

1. Set the aircraft’s current coordinates as the Home Point.

2. Set the remote controller’s current coordinates as the Home Point.

Ensure the space above the remote controller’s GNSS module (located beneath the DJI logo) is not obstructed and that there are no tall buildings around when updating the Home Point.

Follow the instructions below to update the Home Point:

1. Go to DJI GS RTK > Fly.

2. Tap > , select in Home Point settings to set the aircraft's current coordinates as the Home Point.

3. Tap > , select in Home Point settings to set the remote controller's current coordinates as the Home Point.

4. The Aircraft Status Indicator will blink green to indicate that the new Home Point has successfully been set.

Failsafe RTH

The Forward Vision System allows the aircraft to create a real-time map of its ight route as it ies. If the

Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH will be automatically activated if the remote controller signal is lost for more than three seconds. The aircraft will

plan its return route and retrace its original ight route home. During RTH, if the remote controller signal is

recovered, users can control the aircraft altitude and speed. Press the RTH button once to cancel RTH.

Smart RTH

Use the RTH button on the remote controller when GNSS is available to initiate Smart RTH. The aircraft will then automatically return to the last recorded Home Point. Use the remote controller to control the aircraft’s speed or altitude to avoid a collision during the Smart RTH process. As the aircraft returns, it will use the primary camera to identify obstacles as far as 300m in front, allowing it to plan a safe route home. Press and hold the Smart RTH button once to start the process, and press the Smart RTH button again to terminate the procedure and regain full control of the aircraft.

Low Battery RTH

The low battery level failsafe is triggered when the DJI Intelligent Flight Battery is depleted to a point that

may aect the safe return of the aircraft. The user can cancel the RTH procedure by pressing the RTH

button on the remote controller. The thresholds for these warnings are automatically determined based on the aircraft’s current altitude and distance from the Home Point. The Low Battery RTH will only be triggered

once during the same ight.

The aircraft will land automatically if the current battery level can only support the aircraft long enough to descend from its current altitude. The user cannot cancel the auto landing but can use the remote controller to alter the aircraft’s orientation during the landing process.

The Battery Level Indicator is displayed in the DJI GS RTK app, and is described below:

alert and will not trigger RTH.

Precision Landing

The aircraft automatically scans and attempts to match the terrain features underneath during Return to Home. When current terrain matches home point terrain, the aircraft will start landing immediately to achieve precision landing.

Phantom 4 RTK User Manual

Landing Protection is active during precision landing. Precision Landing performance is subject to the following conditions:

a) Home point is recorded upon take o, and cannot not be refreshed during ight. b) Aircraft must take o vertically. Take o altitude must be greater than 7 meters. c) Home point terrain features remain largely unchanged. d) Home point terrain with no distinctive features will aect the performance. e) Lighting conditions cannot be too light nor too dark.

The following actions are available during landing:

a) Pull throttle down to accelerate landing. b) Moving the control sticks in any other direction will stop Precision Landing. The aircraft will descend

vertically and Landing Protection will remain active.

RTH Safety Notices

The aircraft cannot avoid obstruction during RTH when the Forward Vision System is disabled. Users can use the remote controller to control aircraft altitude and speed. It is important to set a suitable Failsafe altitude before

20m

each flight. Launch the DJI GS RTK app, tap Failsafe Altitude.

If the aircraft is ying under 65 feet (20 meters) and RTH (including Smart RTH, Low Battery RTH and Failsafe RTH) is triggered, the aircraft will rst

automatically ascend to 65 feet (20 meters) from the current altitude. You can only cancel the ascending by exiting the RTH.

and tap to set the

The aircraft will automatically descend and land if RTH is triggered when the

aircraft ies within a 16-feet (5 meters) radius of the Home Point and when

the aircraft altitude is under 98 feet (30 meters), or if the obstacle sensing function is disabled. The aircraft will not ascend, and will land immediately at the current location.

Aircraft cannot return to the Home Point when GNSS signal is weak

( [ ] displays grey) or the module is unavailable.

If you move the throttle stick after the aircraft rises above 65 feet (20 meters) but below the pre-set Failsafe RTH altitude, the aircraft will stop ascending and immediately return to the Home Point.

Phantom 4 RTK User Manual

Obstacle Avoidance During RTH

Aircraft can now sense and actively attempt to avoid obstacles during RTH, provided that the lighting conditions are adequate for the Forward Vision System. Upon detecting an obstacle, the aircraft will act as follows:

1. The aircraft will use the primary camera to identify obstacles as far as 984 feet (300 meters) in front, allowing it to plan a safe route home.

2. The aircraft decelerates when an obstacle is sensed at 49 feet (15 meters) ahead.

3. The aircraft stops and hovers then starts ascending vertically to avoid the obstacle. Eventually, the aircraft will stop climbing when it is at least 16 feet (5 meters) above the detected obstacle.

4. Failsafe RTH procedure resumes, the aircraft will continue ying to the Home Point at the current altitude.

5 meters

300 meters

15 meters

The Obstacle Sensing function is disabled during RTH descent. Operate with care.

To ensure the aircraft returns home forwards, it cannot rotate during RTH while the Forward Vision

System is enabled.

The aircraft cannot avoid obstacles above, beside, or behind the aircraft.

Landing Protection Function

Landing Protection will activate during auto landing.

1. Landing Protection determines whether the ground is suitable for landing. If so, the aircraft will land

gently.

2. If Landing Protection determines that the ground is not suitable for landing, the aircraft will hover and

wait for pilot conrmation. The aircraft will hover if it detects the ground is not appropriate for landing

even with a critically low battery warning. Only when the battery level decreases to 0% will the aircraft

land. Users retain control of aircraft ight orientation.

3. If Landing Protection is inactive, the DJI GS RTK app will display a landing prompt when the aircraft

descends below 0.3 meters. Tap to conrm or pull down the control stick for 2 seconds to land when

the environment is appropriate for landing.

Landing Protection will not be active in the following circumstances:

•

a) When the user is controlling the pitch/roll/throttle sticks (Landing ground detection will re-activate

when control sticks are not in use) b) When the positioning system is not fully functional (e.g. drift position error) c) When the Downward Vision System needs re-calibration d) When light conditions are not sucient for the Downward Vision System

• If an obstacle is within 1-meter of the aircraft, the aircraft will descend to 0.3m above the ground

and hover. The aircraft will land upon with user conrmation.

number is more than 125, users have to reimport KML/KMZ les that meet the requirements.

Photogrammetry

After the operation area has been set, and settings have been congured, the DJI GS RTK app produces

a flight route based on the user’s input. After planning, the aircraft can carry out automated operations

following the ight route. There are three types of Photogrammetry operations: 2D, 3D (Double Grid) and 3D (Multi-oriented). The 2D ight route is s-shaped and can be used for digital orthophoto map (DOM). The 3D (Double Grid) ight route consists of s-shaped routes that are crisscrossed to create 3D models. The default values of the gimbal pitch angle for the two types are dierent. The 3D (Multi-oriented) ight routes consist of

data (e.g. operation progress, breakpoint) after the aircraft is powered o for battery replacement. Follow the

instructions in Operation Resumption to resume the operation after restarting the aircraft.

Vision System and Infrared Sensing System

The main components of the Vision System are located on the front, rear and bottom of the aircraft, including [1] [2] [4] three stereo vision sensors and [3] two ultrasonic sensors. The Vision System uses ultrasound and image data to help the aircraft maintain its current position, enabling precision hovering indoors or in environments where a GNSS signal is not available. The Vision System constantly scans for obstacles, allowing the aircraft to avoid them by going over, around, or hovering. The Infrared Sensing System consists [5] of two 3D infrared modules on both sides of the aircraft. These

scan for obstacles on both sides of the aircraft and is active in certain ight modes.

Calibrating Sensors

Vision Systems cameras installed on the aircraft are calibrated on delivery. However these cameras are vulnerable to excessive impact and will require occasional calibration via DJI Assistant 2 for Phantom. Follow the steps below to calibrate the sensors.

Align the boxes

Pan and tilt the aircraft

Using Vision Positioning

Vision Positioning is activated automatically when the aircraft is turned on. No further action is required. Vision Positioning is typically used in indoor environments, where GNSS is unavailable. Using the sensors that are built into the Vision System, the aircraft can hover precisely even without GNSS. The Downward Vision System works best when the aircraft is at altitudes of under 33 ft (10 m). Operate the aircraft with great caution when

ying at high speeds at low altitudes (under 0.5 m).

Follow the steps below to use Vision Positioning:

1. Turn on the aircraft. The aircraft status indicator will ash green two times, which indicates the Vision Po-

sitioning is ready.

2. Gently push the left stick up to lift o and the aircraft will hover in place.

Phantom 4 RTK User Manual

Assisted Braking from Obstacle Sensing

Powered by the Obstacle Sensing, the aircraft will now be able to actively brake when obstacles are detected around the aircraft. Note that Obstacle Sensing function works best when lighting is adequate

and the obstacle is clearly marked or textured. The aircraft must y at no more than 31mph (50kph) to allow sucient braking distance.

The 3D Infrared Sensing System is only active in Beginner mode* and Tripod mode*. Fly with

caution.

The performance of your Vision System and Infrared Sensing System are aected by the surface being

own over. Ultrasonic sensors may not be able to accurately measure distances when operating above

sound-absorbing materials and the camera may not function correctly in suboptimal environments. The aircraft will switch from P-mode to A-mode automatically if neither vision sensors nor ultrasonic sensors and Infrared Sensing System are available. Operate the aircraft with great caution in the following situations:

a) Flying over monochrome surfaces (e.g. pure black, pure white, pure red, pure green).

b) Flying over a highly reective surfaces.

c) Flying at high speeds of over 31mph (50kph) at 2 meters or over 11mph (18kph) at 1 meter. d) Flying over water or transparent surfaces. e) Flying over moving surfaces or objects. f) Flying in an area where the lighting changes frequently or drastically. g) Flying over extremely dark (lux < 10) or bright (lux > 100,000) surfaces. h) Flying over surfaces that can absorb sound waves (e.g. thick carpet). i) Flying over surfaces without clear patterns or texture. j) Flying over surfaces with identical repeating patterns or textures (e.g. tiling).

k) Flying over inclined surfaces that will deect sound waves away from the aircraft. l) Flying over obstacles with too small eective infrared reective surface.

m) DO NOT position the sides of two aircraft toward each other to avoid interference between

the 3D infrared modules. n) DO NOT cover the protective glass of the infrared module. Keep it clean and undamaged. o) Flying at high speed at low altitude (under 0.5 m).

Keep sensors clean at all times. Dirt or other debris may adversely aect their eectiveness. Vision Positioning is only eective when the aircraft is at altitudes of 0.3 to 10 meters. The Vision Positioning may not function properly when the aircraft is ying over water.

The Vision System may not be able to recognize pattern on the ground in low light conditions (less

than 100 lux).

Do not use other ultrasonic devices with frequency of 40 kHz when Vision System is in operation.

* This mode will be supported later.

Phantom 4 RTK User Manual

RTK Functions

The Phantom 4 RTK has a built-in DJI Onboard D-RTK, which provides more accurate data for centimeterlevel positioning to improve operation precision when using with the DJI D-RTK 2 High-Precision GNSS Mobile Station or Network RTK service. The onboard D-RTK, providing precision position and speed information combined with optimized algorithms, is more accurate than a standard compass sensor and

functions even with magnetic interference from metal structures, ensuring stable ight. If the RTK signal is weak and dierential data cannot be transmitted during a Photogrammetry or Waypoint Flight operation, users can read the raw satellite observations* recorded in the microSD card in the aircraft after the ight, and

then use PPK technology to achieve centimeter-level positioning.

Enable/Disable RTK

Ensure that the “RTK Function” is enabled and RTK service type is correctly set (D-RTK 2 Mobile Station or Network RTK service) before each use. Go to Camera View in the DJI GS RTK app > > RTK to view and set.

Make sure to disable RTK function if not in use. Otherwise, the aircraft will not be able to take o when there is no dierential data.

Using with the DJI D-RTK 2 Mobile Station

1. Refer to the D-RTK 2 Mobile Station User Guide to complete linking between the aircraft and the mobile station and setup of the mobile station.

2. Power on the mobile station and wait for the system to start searching for satellites. The RTK status icon on top of the Camera View in the DJI GS RTK app will show to indicate that the aircraft has obtained

and used the dierential data from the mobile station.

After enabling the RTK function and connecting to a data source, be sure to wait for the aircraft’s

RTK module to nish initializing and the RTK / GNSS signal strength icon in the app shows FIX so that the aircraft can take o.

Using with the Network RTK Service

The Network RTK service uses the remote controller instead of the base station to connect to an approved

Network RTK server for dierential data. Keep the remote controller on and connected to the Internet when

using this function.

1. Ensure that the remote controller is connected to the aircraft and has access to the Internet.

2. Go to Camera View in the DJI GS RTK app > > RTK, select the RTK service type to custom network

RTK, and then input the network information.

3. Wait for the remote controller to be connected with the Network RTK server. The RTK status icon on top

of the Camera View in the DJI GS RTK app will show to indicate that the aircraft has obtained and used the RTK data from the server.

* The raw satellite observations are stored in the same directory as the aerial photos. They will only be recorded

during Photogrammetry or Waypoint Flight operations. For Waypoint Flight operations, route recording should be disabled in Route Settings. Otherwise, the raw satellite observations cannot be recorded. In other

situations, such as ying the aircraft and shooting manually, the data will not be recorded.

Phantom 4 RTK User Manual

Flight Recorder

Flight data is automatically recorded to the internal storage of the aircraft. To access this data, connect the aircraft to the PC through the Micro USB port and launch the DJI Assistant 2.

Gimbal and Camera

This section provides the technical

specications of the camera and

explains the gimbal’s operation modes.

Gimbal and Camera

Camera

Prole

The Phantom 4 RTK camera uses a 1-inch CMOS sensor with eective pixels of 20 M and a 24 mm (35 mm format equivalent) wide-angle lens. It is equipped with a blue glass lter to deliver enhanced picture quality and a UV lens for additional protection. An ND lter can be used when the operating environment is too

bright.

The Phantom 4 RTK supports the capture of 4K at 30fps and a maximum video bitrate of 100 Mbps.

The 20 megapixel photos taken by Phantom 4 RTK is the result of the application of advanced image processing technique. A mechanical shutter with a 1/2000 max speed eliminates rolling shutter distortion when capturing stills of fast moving objects.

Camera Micro SD Card Slot

To store your photos and videos, insert the microSD card into the slot as shown below before turning on the aircraft. The Phantom 4 RTK comes with a 16 GB microSD card and supports microSD cards up to 128 GB. A UHS-1 and above microSD card is recommended due to their fast read and write speeds that support high-resolution video data. Users can read the photos and videos, and the raw satellite observations during Photogrammetry and Waypoint Flight operations from the microSD card.

Do not remove the microSD card from the aircraft when it is shooting.

To ensure the stability of the camera system, single video recordings are capped at 30 minutes.

Phantom 4 RTK User Manual

Micro USB Port

Turn on the aircraft and connect a Micro USB cable to the Micro USB Port to update rmware,

Gimbal Operation Modes

Two gimbal operation modes are available. Switch between the different operation modes on the gimbal

settings page of the DJI GS RTK app. Refer to the table below for details:

Follow Mode

FPV Mode

A gimbal motor error may occur in these situations:

(1) the aircraft is placed on uneven ground or the gimbal’s motion is obstructed. (2) the gimbal has been subjected to an excessive external force, such as a collision. Please take

o from at, open ground and protect the gimbal at all times.

Flying in heavy fog or clouds may make the gimbal wet, leading to temporary failure. The gimbal

will recover full functionality after it dries.

It is normal for the gimbal to produce a short beeping tone upon initialization.

In the case of less exposure time (no more than 1/200 second) or ight in S-mode with full

remote controller stick movement, the aerodynamic vibration of the aircraft may increase due to aerodynamic forces. This can make the gimbal more susceptible to wind, causing photos

to show a noticeable dynamic deformation (i.e., the “rolling shutter" eect). In such cases, it is suggested to increase the exposure time by using the lter or reducing the lens aperture, or reduce ying with smaller remote controller stick movement for better picture performance.

The angle between the gimbal’s orientation and aircraft’s nose remains constant at all times.

The gimbal will synchronize with the movement of the aircraft to provide a

rst-person perspective ying experience.

DJI GS RTK App

Cloud PPK Service

PPK is a post-processing dierential correction technique that produces results with centimeter-level positioning

accuracy. Unlike RTK (real-time kinematic), PPK records rover data and base station data separately to conduct post-process calculations and is therefore not restricted by the real-time communication link and protocols between the base station and the rover. In addition, PPK has a longer baseline distance than RTK, improving reliability. The DJI GS RTK app’s Cloud PPK Service (premium add-on) supports multiple base station data sources, enabling users to connect to the cloud server for PPK calculations.

Phantom 4 RTK User Manual

Purchase

Once purchased, the Cloud PPK Service will be bound to the aircraft SN. The app can only recognize operation data that corresponds to an aircraft SN with Cloud PPK Service activated.

Flight

This section describes safe ight practices and ight restrictions.

Flight

Once the pre-ight preparation is complete, it is recommended to hone your ight skills through training and practice ying safely. The altitude limit is 1, 640 feet (500 meters). Avoid ying at any altitudes higher. It is important to understand basic ight guidelines for the safety of both you and those around you. Refer to the

Disclaimer and Safety Guidelines for more information.

Flight Environment Requirements

1. Do not use the aircraft in severe weather conditions. These include wind speeds exceeding 10 m/s,

snow, rain and fog.

2. Only y in open areas. Tall structures and large metal structures may aect the accuracy of the on-board

compass and GNSS system.

3. Avoid obstacles, crowds, high voltage power lines, trees, and bodies of water.

4. Minimize interference by avoiding areas with high levels of electromagnetism, including base stations and

radio transmission towers.

5. Aircraft and battery performance is subject to environmental factors such as air density and temperature.

Be very careful when ying at altitudes greater than 19, 685 feet (6000 meters) above sea level, as the performance of the battery and aircraft may be aected.

6. In the Earth’s polar regions the aircraft can only operate in Attitude mode or using vision positioning.

GEO (Geospatial Environment Online) System

Introduction

DJI’s Geospatial Environment Online (GEO) System is a global information system committed to providing real-time airspace information within the scope of international laws and regulations. GEO provides flight information, flight times and location information to assist Unmanned Aerial Vehicle (UAV) users in making the best decisions related to their personal UAV use. It also includes

a unique Regional Flight Restrictions feature which provides real-time ight safety and restriction updates and blocks UAVs from ying in restricted airspace. While safety and obeying air trafc

control laws is a paramount concern, DJI recognizes the need for exceptions to be made under special circumstances. To meet this need, GEO also includes an Unlocking feature that enables users to unlock flights within restricted areas. Prior to making their flight, users must submit an unlock request based on the current level of restrictions in their area.

GEO Zones

DJI’s GEO System designates safe flight locations, provides risk levels and safety concerns for

individual ights, and offers restricted airspace information, which can be viewed by users in real

time on the DJI GS RTK app. The locations designated by GEO are called GEO Zones. GEO Zones

are specic ight areas that are categorized by ight regulations and restrictions. GEO Zones that prohibit ight are implemented around locations such as airports, power plants, and prisons. They can also be temporarily implemented around major stadium events, forest res, or other emergency

situations. Certain GEO Zones do not prohibit flight but do trigger warnings informing users of

potential risks. All restricted ight areas are referred to as GEO Zones, and are further divided into

Warning Zones, Enhanced Warning Zones, Authorization Zones, Altitude Zones, and Restricted Zones. By default, GEO limits flights into or taking off within zones that may result in safety or security concerns. There is a GEO Zone Map, which contains comprehensive global GEO Zone

information on the ofcial DJI website: https://www.dji.com/ysafe.

Phantom 4 RTK User Manual

The GEO System is for advisory purposes only. Individual users are responsible for checking ofcial sources and determining which laws or regulations may apply to their ight. In some instances,

DJI has selected widely-recommended general parameters (such as a 1.5-mile radius at airports) without making any determination as to whether these guidelines match regulations that apply to

specic users.

Authorization Zones:

Authorization Zones can be unlocked by authorized users with a DJI-verified account. SelfUnlocking privileges must be applied for online.

Altitude Zones: Restricted Zones:

obtained permission to y in a Restricted Zone, please go to https://www.dji.com/ysafe or contact ysafe@dji.com to unlock the zone.

DJI GEO Zones aim to ensure the user’s flight safety, but it cannot be guaranteed to be in full compliance with local laws and regulations. Users should check local laws, regulations, and

regulatory requirements before each ight and are responsible for the ight safety.

All intelligent ight features will be affected when DJI aircraft y nearby or into GEO Zones. Such interference includes, but is not limited to, decreased speed, takeoff failure, and ight termination.

Users receive a warning message with information relevant to their ight.

Users receive a prompt from the GEO System at the time of ight. They

Users receive a warning message and the flight is prohibited by default.

Flights are limited to a specic altitude.

Flights are completely prohibited. UAVs cannot y in these zones. If you have

Flight Restrictions

Introduction

UAV operators should abide by all ight regulations established by the relevant government and

regulatory agencies, including the ICAO and the FAA. For safety reasons, flights are restricted by default, which helps users operate DJI products safely and legally. Flight restrictions include altitude and distance limits, and GEO Zones.

When Global Navigation Satellite Service (GNSS) is available, altitude limits, distance limits, and

GEO Zones are all taken into account to ensure ight safety. Otherwise, only altitude limits take

effect.

Maximum Altitude & Radius Restrictions

Maximum flight altitude restricts an aircraft’s flight altitude, while maximum radius restricts its distance. These limits can be set using the DJI GS RTK app.

Max Radius No limit. N/A

When an aircraft exceeds a specied limit, the pilot can still control the aircraft but it will be unable

to y any farther.

When an aircraft exceeds the max radius it automatically ies back within range when GNSS

signal is strong.

For safety reasons, do not y near airports, highways, railway stations, railway lines, city centers,

or other sensitive areas. Only y aircraft in areas that are within your direct line of sight.

GEO Unlocking

Due to differing laws and regulations between countries and regions, and differing ight restrictions

between GEO Zones, DJI provides users with two methods for unlocking GEO Zones: Self-Unlocking and Custom Unlocking. Self-Unlocking is used for Authorization Zones, where the user is required to submit an unlock request by authenticating their phone number for a registered DJI account. This feature is only available in certain countries. Users can choose whether to submit their unlock request via the website

at https://www.dji.com/ysafe (Scheduled Self-Unlocking), or through the DJI GS RTK app (Live

Self-Unlocking).

Custom Unlocking is based on special requirements for individual users. It sets a special ight

Phantom 4 RTK User Manual

area that users can unlock by providing ight permission les according to their specic GEO

Zone and other requirements. It is available in all countries and can be applied for on the website:

https://www.dji.com/ysafe.

7. Ensure that the sensors for the Vision System and Infrared Sensing System are clean.

Calibrating the Compass

Only calibrate the compass when the DJI GS RTK app or the status indicator prompt you to do so. Observe the following rules when calibrating your compass:

DO NOT calibrate your compass where there is a chance of strong magnetic interference, such as

magnetite, parking structures, and steel reinforcements underground.

DO NOT carry ferromagnetic materials with you during calibration such as cellular phones.

The DJI GS RTK app will prompt you to resolve the compass issue if the compass is aected by

strong interference after calibration is complete. Follow the prompted instructions to resolve the compass issue.

Calibration Procedures

Choose an open area to carry out the following procedures.

1. Tap the Aircraft Status Bar in the app and select “Calibrate”, then follow the on-screen instructions.

2. Hold the aircraft horizontally and rotate 360 degrees. The Aircraft Status Indicators will display a solid

green light.

3. Hold the aircraft vertically, with nose pointing downward, and rotate it 360 degrees around the center

axis.

Phantom 4 RTK User Manual

4. Re-calibrate the aircraft if the aircraft status indicators glows blinking red.

If the Aircraft Status Indicator blinks red and yellow after the calibration procedure, move your

aircraft to a dierent location and try again.

DO NOT calibrate the compass near metal objects such as a metal bridge, cars, scaolding.

If the aircraft status indicators are blinking red and yellow alternately after placing the aircraft on

the ground, the compass has detected magnetic interference. Change your location.

Starting/Stopping the Motors

Starting the Motors

A Combination Stick Command (CSC) is used to start the motors. Push both sticks to the bottom inner or outer corners to start the motors. Once the motors have started spinning, release both sticks simultaneously.

Stopping the Motors

There are two methods to stop the motors. Method 1: When the aircraft has landed, push the left stick down , then conduct the same CSC that was used to start the motors, as described below . Motors will stop immediately. Release both sticks once motors stop. Method 2: When the aircraft has landed, push and hold the left stick down. The motors will stop after three seconds.

Method 1 Method 2

Stopping Motors Mid-flight

Perform the CSC to stop the motors. It can be enabled in the app. Go to Camera View > > > Ad-

vanced Settings to set the Urgent Stop Mode. Only stop motors mid-ight in emergency situations when

doing so can reduce the risk of damage or injury.
