Introduction

The Agras MG-1S / Agras MG-1S RTK (abbreviated as “MG-1S” / “MG-1S RTK”) is a batterypowered multirotor aircraft designed for agricultural applications in variety of environments and

terrains, including elds, forests and orchards. It is dust-proof, water-proof (IP43 protection rating, IEC standard 60529) and made of anti-corrosive materials, allowing it to be rinsed clean.

The MG-1S / MG-1S RTK contains DJI’s dedicated A3 redundancy system with dual IMU and dual compass capabilities, ensuring safe and stable operation at all times. The MG-1S RTK has a built-in DJI Onboard D-RTK*, which provides more accurate data for centimeter-level positioning. F-mode,

uses the DJI MG app for automatic intelligent ight planning. Radar Terrain Follow, consists of three

radar modules, one on the front, rear, and underside of the aircraft, measuring distances from all three directions for terrain follow applications.

The remote controller is equipped with a bright, dedicated screen with a built-in Android system that runs the DJI MG app independently. The app features intelligent operation planning functions to

produce ight routes automatically, according to marked operation areas and obstacles. The DJI MG

app is able to display the system status, convenient when your aircraft is spraying far away from you.

Feature Highlights

The MG-1S uses a DJI dedicated ight control system, providing three operation modes: Smart,

Manual, and Manual Plus. This system also includes three flight modes: P-mode (Positioning), A-mode (Attitude), and F-mode (Function).

In Smart operation mode, the aircraft will travel along a pre-planned route and spray its liquid

payload. Users can set the line spacing, ying speed, and other parameters. The MG-1 can cover

an area of 7-10 acres per hour.

In Manual operation mode, users can start and stop spraying manually and also adjust the spray rate.

In Manual Plus operation mode, ight speed is restricted and heading is locked. Except for the

heading, users can control the aircraft's movement via control sticks. Press button C1/C2 and the

aircraft will y one line spacing to the left/right.

The DJI MG app will automatically produce ight routes based on your planned tasks, which the

aircraft will perform once in F-mode.

The MG-1S also includes two intelligent memory features: Operation Resumption and System Data

Protection. When the operation or ight mode is changed from Smart operation mode or F-mode,

Operation Resumption records a set return point for the aircraft when Smart Operation Mode is reinstated. System Data Protection keeps system data for 30 seconds, even when powered off, so users can resume their missions after replacing the battery.

The spraying system includes a spray tank, flow meter, liquid level meter, sprinklers, and other accessories. The four sprinklers placed on the aircraft’s two sides provide evenly distributed spraying and coverage of the liquid payload. The nozzles on the MG-1S / MG-1S RTK can also be swapped out to meet the needs of different applications.

An advanced Radar Terrain Follow System consists of three radar modules located on the front, rear, and underside of the aircraft. It works automatically in Smart or Manual Plus operation mode or F-mode.

The MG-1S RTK has a built-in DJI Onboard D-RTK, providing more accurate data for centimeter-level positioning when used with the DJI D-RTK Base Station. An optional DJI D-RTK Handheld Mapper is

designed for more precise eld planning, enhancing agricultural operations with the Intelligent Operation

Planning System within the DJI MG app.

* This should be used with a DJI D-RTKTM Base Station (purchased additionally). Refer to RTK Functions

(p. 41) for details.

Aircraft

Prole

The MG-1S / MG-1S RTK uses DJI's dedicated A3 Flight Controller to provide three ight modes

and operation modes for various applications. A Radar Terrain Follow System guides the aircraft

to maintain a constant distance above crops in each ight or operation mode. Functions such as

operation resumption, system data protection, empty tank warning, Return to Home (RTH) and low battery level warning are also available. The MG-1S RTK has a built-in DJI Onboard D-RTK, providing more accurate data for centimeter-level positioning to ensure more precise and stable

ight when used with the DJI D-RTK Base Station.

When using your MG-1S / MG-1S RTK for the rst time, activate it in the DJI MG app. Your

DJI account and internet connection are required.

Effective use of pesticides relies on pesticide density, spray rate, spray distance, aircraft

speed, wind speed and wind direction. Consider all factors when using pesticides.

Always y at an appropriate height above crops to avoid damage.

Operation Modes

When the Flight Mode Switch is set to P, the MG-1S / MG-1S RTK provides Smart, Manual, and Manual Plus operation modes. Switch to one of the three modes via the Operation Mode switch on the remote controller.

Smart Operation Mode

In Smart operation mode, the aircraft will travel along a pre-planned route. Operation resumption, data protection, and the Radar Terrain Follow System are available in this mode. Use the Settings dial on the remote controller or app to adjust work efficiency (including flying speed and spray rates). Smart operation mode is recommended for large, rectangular spray areas.

Operation Route

The aircraft will travel along a pre-designated square zig-zag route after recording turning points A and B. Under optimal working conditions, the aircraft maintains distance from the vegetation. The length of the dotted lines, called Line Spacing, can be adjusted in the DJI MG app.

be adjusted in the DJI MG app.

The aircraft cannot be controlled when using the C1 or C2 buttons to steer the aircraft to

the left or right. Switch to Manual operation mode in case of emergency, and the aircraft

will stop ying.

Operation Resumption

When exiting Smart Operation Mode or a route task, the aircraft will record a breakpoint. The Operation Resumption function allows you to pause an operation temporarily (e.g., to refill the spray, change battery, and avoid obstacles manually) and then resume operation at the breakpoint.

Instructions

Recording a Breakpoint

Exit Smart operation mode or F-mode through one of the following methods and the aircraft will record its location as a breakpoint if GNSS signal is strong:

1. Set the Operation Mode switch out of Smart operation mode.

2. Initialize the RTH procedure.

3. Set the Flight Mode switch out of P-mode or F-mode.

4. Push the Pitch or Roll stick in any direction on the remote controller.

Ensure that GNSS signal is strong when using the Operation Resumption function.

Otherwise, the aircraft cannot record and return to the break point.

The breakpoint will be updated as long as you set the Operation Mode switch to any other

mode besides Smart operation mode, the Flight Mode switch to any other mode besides P-mode or F-mode, and you trigger RTH during Smart operation mode or F-mode.

Resume Operation

1. Exit Smart operation mode or F-mode through one of the four above methods. The current

location of the aircraft will be recorded as the breakpoint.

2. Fly the aircraft to a safe location before resuming operation. If the Radar Terrain Follow System

is enabled, adjust the spraying distance between the aircraft and the vegetation to be within

working range (1.5-3.5 m).

Page 36

AGRAS MG-1S User Manual

To avoid risk, ensure that the aircraft has completely avoided the obstacle before

resuming operation.

In the event of an emergency, ensure that the aircraft is in normal status and then y the

aircraft manually to a safe area to resume operation.

Repeat the instructions above to exit and resume operation in the event of an emergency (i.e., whenever obstacle avoidance is required) during the return procedure.

System Data Protection

The System Data Protection feature enables the aircraft to retain vital system data (e.g., Point A, Point B, breakpoint) for about 30 seconds after the aircraft is powered off. Retaining vital system data allows the aircraft to resume operation after a short, temporary pause. Follow the instructions below to use this feature:

1. Exit Smart operation mode or F-mode. The current location of the aircraft will be recorded as the

breakpoint.

2. Land the aircraft and stop the motors.

3. Once the aircraft is powered off, System Data Protection is automatically triggered, indicated by

The Aircraft Status Indicator glowing solid green.

4. Replace the battery within the 30-second window

5. Restart the aircraft and enter Manual operation mode.

6. Ensure that the GNSS signal is strong, then start the motors.

7. Follow the instructions in Operation Resumption to resume the operation.

System data can only be retained for 30 seconds. DO NOT power off the aircraft for more than 30 seconds if you want to resume operation, as system data will be lost.

Radar Terrain Follow System

Prole

The Radar Terrain Follow System consists of forward, rear, and downward radar modules that use microwave technology to follow the terrain. In an optimal operating environment, the system can predict the distance between the aircraft and the crop or other surface in forward, rear, and

downward directions to y at a constant distance to ensure even spraying. The function is enabled by default, and can be disabled in the DJI MG app. When enabled, the aircraft will y above the

crop at a constant spraying distance in Smart and Manual Plus operation modes and F-mode. In Manual operation mode, the system can also measure the spraying distance above the vegetation

or other surface, but the aircraft will not be able to y at a constant spraying distance.

Using the Radar Terrain Follow System

1. Ensure that you have enabled the Radar Terrain Follow System in the DJI MG app.

2. Congure the desired spraying distance (1.5-3.5 m).

3. If using Smart or Manual Plus operation mode, ensure that you have set the Flight Mode switch

to P and the Operation Mode switch to M. If using F-mode, ensure that the Flight Mode switch is set to F. Fly the aircraft above the vegetation and adjust the distance between the aircraft and the

vegetation to a value within the working range (1.5-3.5 m).

Page 38

AGRAS MG-1S User Manual

4. Set the Flight Mode and Operation Mode switches to the desired position to enter the

corresponding mode. If the operating environment is ideal, the aircraft will fly above the vegetation at the preset height.

The Radar Terrain Follow System will only maintain a xed distance from vegetation within

its working range (1.5-3.5 m).

Observe the aircraft’s distance from the vegetation at all times. Operate with extra caution when flying over inclined surfaces (depending on aircraft

speed). Recommended maximum inclination at different speeds: 15° at 1 m/s, 6° at 3 m/s and 3° at 5 m/s.

Obey local radio transmission laws and regulations.

Updating the Home Point

You can update the Home Point in the DJI MG 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 MG > Operation View.

2. Tap > , select in Home Point settings to set the remote controller’s current coordinates

as the Home Point.

3. Tap > , select in Home Point settings to set the aircraft’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.

RTH Safety Notices

The aircraft cannot avoid obstacles during RTH. Users can only control the speed and altitude of the aircraft. If the aircraft is in risk of collision, exit RTH immediately.

Before each ight, it is important to set an RTH altitude that is appropriate for the

given environment. Go to DJI MG > Operation View > > > Set Return to Home Altitude.

15 m

If the aircraft is ying under 15 meters and RTH (including Smart and Failsafe RTH) is triggered, the aircraft will rst automatically ascend to 15 meters from the current altitude. You cannot control the aircraft during this ascent. In Smart RTH, you can

exit RTH to cancel automatic ascent by pressing the RTH button once.

20 m

The aircraft automatically descends and lands if RTH is triggered when the aircraft

ies within a 20 m radius of the Home Point.

The aircraft cannot return to the Home Point when GNSS signal is weak ( displays red) or is unavailable.

When the RTH altitude is set to more than 15 m and the aircraft is ascending between 15 m and the preset RTH altitude, the aircraft will stop ascending and

immediately return to the Home Point if you push the throttle stick.

Low Battery Warnings

There are two low battery warnings:

1. Low Battery Warning: The Aircraft Status Indicator slowly blinks red. Fly the aircraft back and land

it as soon as possible, stop the motors, and replace the batteries.

2. Critical Battery Warning: the Aircraft Status Indicator rapidly blinks red. The aircraft will begin to

descend and land automatically.

Users can set the threshold of both low battery level warnings.

RTK Functions (for MG-1S RTK only)

The MG-1S RTK has a built-in DJI Onboard D-RTK, which provides more accurate data for centimeter-level positioning to improve agricultural operation when using with DJI D-RTK Base Station. The aircraft’s heading reference from the dual antennas of the onboard D-RTK is more accurate than a standard compass sensor and can withstand magnetic interference from metal structures.

Ensure to use RTK functions within the RTK data transmission distance. Refer to

Specications for details.

Enable/Disable RTK

Ensure that the “RTK Module” is enabled and RTK data source is correctly set (D-RTK Base Station) before each use. Go to Operation View in the DJI MG app > > RTK > RTK Module to view and set.

Using with the DJI D-RTK Base Station

1. Refer to the D-RTK Base Station User Guide to complete linking between the aircraft and base

station and setup of the base station.

2. Power on the base station and wait for the system to start searching for satellites. The RTK status

icon on top of the Operation View in the DJI MG app will show to indicate that the aircraft has obtained and used the RTK data from the base station.

exceeding 25 mm or 0.98 in within a 12-hour period), high winds exceeding 17 mph (28 kph),

fog, snow, lightning, tornadoes, or hurricanes.

2. Only y in open areas. Tall buildings and steel structures may affect the accuracy of the compass

and the GNSS signal.

3. Maintain line of sight of the aircraft at all times, and avoid ying near obstacles, crowds, animals,

trees, and bodies of water.

4. Avoid ying in areas with high levels of electromagnetism, including mobile phone base stations

and radio transmission towers.

5. Ensure that there is a strong GNSS signal in the Smart or Manual Plus operation mode or F-mode.

6. DO NOT operate the aircraft indoors.

7. The MG-1S / MG-1S RTK cannot operate in P or F-mode within the earth’s polar regions.

Flight Limits and No-Fly Zones

Users can set ight limits on height and distance.

Unmanned aerial vehicle (UAV) operators should abide by the regulations from self-regulatory organizations such as the International Civil Aviation Organization, the Federal Aviation

Administration, and their local aviation authorities. For safety reasons, ight limits are enabled by

default to help users operate this aircraft safely and legally.

When operating in P or F-mode, the height and distance limits and no-y zones work together to monitor ight. In A-mode, only the height limit prevents the aircraft from going above 50 meters.

Maximum Height and Radius Limits

Users can change the maximum height and radius limits in the DJI MG app. Once complete, your

aircraft will y in a restricted cylinder that is determined by these settings. The tables below show

the details of these limits.

Maximum Flight Altitude

P-mode or F-mode (with strong GNSS signal)

Max Height Flight altitude must be below the preset height. Max Radius No limits.

If you y into a no-y zone, you can still control the aircraft, but cannot y it further.

If the aircraft loses GNSS signal or is in A-mode and flies out of the max radius but

regains GNSS signal or the ight mode is switched from A-mode to other modes (with strong GNSS signal) afterwards, it will y back within range automatically.

No-Fly Zones

Detailed no-fly zones are listed on the DJI official website at http://flysafe.dji.com/no-fly. No-fly

zones are divided into airports and restricted areas. Airports include major airports and ying elds

where manned aircraft operate at low altitudes. Restricted areas include borders between countries

or sensitive sites. The details of the no-y zones are explained below (GNSS required):

R mi around the restricted area (depending on the regulation) is a no-y zone, inside which takeoff and ight are prohibited.

When to Recalibrate

1. Compass data is abnormal, and the Aircraft Status Indicator is alternately blinking red and yellow.

2. Flying in a new location, or a location that is different from your last ight.

3. The mechanical structure of the aircraft has changed.

4. Severe drifting occurs in ight (e.g., the aircraft has difculty ying in a straight line).

Calibrating the Flow Meter

It is recommended to calibrate the ow meter before your rst ight to ensure precision spraying.

Ensure that bubbles in the hoses are completely discharged before calibrating.

Fill the spray tank with 5-10 L water when calibrating. Use a standard measuring cup of 5

L volume to ensure accuracy.

Perform calibration in Smart operation mode or F-mode, with an end-to-end flying

distance of over 100 m.

It is recommended to set the pesticide usage for spray to about 1.7 gal/ac.

Calibration Procedures

1. When calibrating the flow meter in F-mode, plan the field first. Refer to Intelligent Operation Planning System (p. 30) for more details.
