Basic Theory

GAIA 160AG agriculture spraying drone is a high performance aircraft capable of offering comprehensive solutions for agricultural care. GAIA 160AG is made of carbon fiber material which features light weight and high strength, the top cover of the fuselage and the tank are made of glass fiber. The frame weight if about

7.25kg. The arm of GAIA160 series hexacopter is pluggable, both the cover and arms can be locked with the quick locking hooks.

The big fuselage of GAIA 160AG makes it possible to install many equipments eg. battery, Gps, flight control system. And all the wires are built into the fuselage. The closed fuselage structure can protect the GAIA 160AG hexacopter from the rain and dust, and also protect other load equipments.

This GAIA 160AG is equipped with a 2.8 meter long tube with four nozzles. The new water-saving nozzles could save the pesticide and improve the efficiency of spraying at the same time. This GAIA 160AG has a grid pesticide container which can prevent the liquids sloshing in the flight. The capacity of pesticide tank is 22.5L, so do not need to add pesticide frequently. The propeller vortex can help the GAIA 160AG evenly spraying the pesticide on the front and back of the plant leaves.

The GAIA 160AG is equipped with powerful motor and high efficiency 30 inch folding propeller, the max lift of one rotor can reach 13kg. The total thrust is over 70kg. The GAIA 160AG supports both manual and automatic flight, it can achieve automatic spraying by the planned flight paths. The motor and ESC use the water-resistant design, and can be applied in different weather conditions. Because of the large liquids load the efficiency of GAIA 160AG is twice as much as other aircraft with 10L payload.

The GAIA 160AG DJI AG 2.0 Version adopts N3-AG 2.0 flight controller and radar sensing system, combined with the new spraying system and intelligent operation planning system, agricultural plant protection efficiency is significantly improved. All these additions make plant protection more accurate and efficient. The downward radar module adopts microwave technology which provides high-precision altitude, so 160AG will fly above the crops at a constant spraying distance to ensure uniformity of the pesticide spraying.

SystemFunctions

Flight Modes

The flight control system includes two flight modes: P-mode (Positioning) and A-mode (Attitude). Toggle the Flight Mode switch on the remote controller to one of the two modes. P-mode (Positioning): The aircraft uses GNSS for positioning and it can only maintain attitude stabilization when GNSS signal is weak. In P-mode, users can start the motors, record Point A and B, and enter Smart operation mode (A-B Route) when the GNSS signal is strong. If using the D-RTK*, it can provide centimeter- level positioning accuracy. A-mode (Attitude): GNSS is not used for positioning, and aircraft can only maintain altitude using the barometer. Aircraft can still record its position and return to the Home Point if a GNSS signal is present.

Attention in Attitude mode

The aircraft will enter attitude mode in the following two situations:

Passive mode: GNSS satellite signal difference or compass is disturbed.

Active mode: The user cuts the remote control flight mode to A position.

In attitude mode, the aircraft is susceptible to external interference, which will cause drift in the horizontal direction; and some functions will not be available. Therefore, in this mode, the aircraft itself cannot achieve fixed-point hovering, and the user needs to manually control the remote controller to realize the aircraft hovering. In this mode, the handling difficulty of the aircraft will be greatly increased. If you want to use this mode,must be familiar with the behavior of the aircraft in this mode and be able to control the aircraft skillfully. Do not fly the aircraft too far away, that will cause the lost of judgment of the aircraft attitude and cause a risk. Once passively entering this mode, it should land to a safe place as soon as possible to avoid an accident. At the same time, should avoid to fly at narrow space where the the GNSS satellite signal is weak,to avoid passive entry into the attitude mode, resulting in flight accidents.

Operation Modes

The system provides Smart, Manual, and Manual Plus operation modes. Switch to one of the three modes via the Operation Mode switch on the remote controller.

Route Planning Mode

In Smart operation mode, the aircraft will travel along a pre-planned route. Operation resumption, data protection, and the Altitude Stabilization System are available in this mode. The spray rate will be adjusted automatically according to the flying speed. Smart operation mode is recommended for large, rectangular spray areas.

Be sure to takeoff in open areas. The task will be automatically cancelled if the motors are started before beginning the task. You will need to recall the task in the task list. Once started, the aircraft will fly to the starting point of the route and lock its heading in the direction of the first turning point for the duration of the flight path. During the task, the aircraft automatically sprays liquid while flying forwards or backwards, and it doesn’t spray liquid while flying left and right. Users can adjust work efficiency (flying speed and spray rate included) and height above the crops in the DJI MG app. During the execution of the job, the user can stop the operation by dialing the emergency stop switch. The aircraft will hover in place and record the breakpoint coordinates, at which point the user is free to manipulate the aircraft. After that, the user can click the Continue button in the App, and the aircraft will automatically fly back to the break coordinate point to continue the job. It is important to pay attention to flight safety during the flight back to the interrupted coordinate point. If the option to allow the switching of the flight mode is turned on in the assistant software, the emergency stop switch is used as the flight mode switch, and the toggle switch may enter the attitude mode, and the aircraft must be carefully operated. The aircraft will hover at the ending point of the flight route after the task is completed.

GAIA 160AG-Agricultural Spraying Drone User Manual

A-B Point Mode

In the A-B point mode, the aircraft can fly and spray pesticides according to specific routes, with job recovery and data protection functions, and can use the radar module for height Fixed and obstacle avoidance. Users can adjust working efficiency (including aircraft speed and spray flow) in real time on the App interface. This mode is suitable for working in a large area with a shape close to a rectangle.

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 for the Altitude Stabilization System, the aircraft maintains distance from the vegetation. The length of the dotted lines, called Operation Gap (Line Spacing), can be adjusted in DJI Assistant 2 or the DJI MG app.

Operation Procedure

Maintain line of sight of the aircraft at all times. Set the Flight Mode switch to P when GNSS signal is strong. Otherwise, Smart operation mode may be unreliable. Always inspect operating environments before flying.

Make sure that the GNSS signal is good, the DJI MG App's working mode toggle button is selected as the “M” manual mode, and the interface displays the manual job (GNSS). Then aircraft is then taken off to the appropriate height.

1. Record Points A and B in Order Users cannot set the Operation Mode switch to Smart operation mode until they have recorded points A and B. Fly the aircraft to the starting point, depicted as Point A/B, hover, and then press Button A/B on the remote controller or tap Point A/B onscreen. The icon for Point A/B will change from gray to purple and the Aircraft Status Indicator will blink red/green after recording the starting points.

GAIA 160AG-Agricultural Spraying Drone User Manual

Points A and B can only be recorded when the aircraft is hovering in Manual operation mode. Update Point B by flying the aircraft to a new position to record. Note that if you update Point A, you must also update Point B. It is recommended to keep the direction of Point A to B parallel to one side of the rectangular spray area for optimal effect. After recording Point A, there will be a menu prompt for work type settings. Set the amount of pesticide per acre and work type. Use the slider to adjust work efficiency. During the task, tap the icon at the top of the screen to adjust parameters. You can also adjust work efficiency via the Settings dial on the remote controller. The DJI MG app will display an icon of line spacing. Tap to adjust the value. The line spacing cannot be adjusted during operation. Switch to Manual or Manual Plus operation mode to adjust the value, then go back to Smart operation mode.

2. Select the Route Press the C1 or C2 buttons on the remote controller to select the operating pattern. Press C1 for Route L and C2 for Route R. The default route pattern is Route R if no selection has been made.

Users can select the route in Manual operation mode only. If the aircraft is in Smart operation mode, select the route after switching to Manual operation mode.

3. Configuring Aircraft Altitude Click on the icon above the App interface to set the desired relative crop height. After the A-B point operation is performed, if the working conditions are met, the radar module will automatically set the height so that the aircraft remains at the same height as the crop while flying.

4. Performing task Click "Start" in the lower right corner of the App interface and slide to automate the job.

If, after recording Points A and B, you fly the aircraft more than five meters away from Point B. Tap Resume, and the aircraft will automatically fly to Point B to re-enter route. During the operation, if the GNSS signal is weak, the aircraft enters the attitude mode and exits the A-B point operation. Users need to carefully control the aircraft. When the GNSS signal is restored, the user can choose to continue the job. During the A-B point operation, if the A or B key is pressed when the aircraft speed is less than

0.3 m/s, the data of points A and B on the current working route will be cleared and the aircraft will hover. The job line spacing defaults to 5 meters and can be set in the app from 3 - 10 meters. In the A-B point mode, the aircraft nose will always remain in the direction from A to B by default, and the user can switch in the apps to always follow the flight direction (coming soon). However, during the whole process of the operation, the user cannot control the heading of the aircraft. When using the control sticks to control the aircraft during the operation, the aircraft will automatically switch to Manual operation mode, complete corresponding flight behavior, and then hover. To resume the A-B point task, tap Resume onscreen. The aircraft will return to operation route, then resume flying along the operation route. During the operation, if the radar module obstacle avoidance function is not turned on, the user can using stick to control the front, rear, left and right direction of the aircraft and the throttle to avoid obstacles on the working route. In the process of operation, the aircraft will not spray pesticides when flying along the route of the operating line spacing, and spray pesticides automatically when flying on the rest routes.

GAIA 160AG-Agricultural Spraying Drone User Manual

5. Starting the Operation a. Press the remote controller’s C1 and C2 buttons simultaneously. The aircraft will align with the line between Points A and B with its heading pointing toward Point B. Fly laterally from Point B to L1/R1, then hover at Point L1/R1 and wait for further instructions. b. Repeat the previous step and the aircraft will fly to the next turning point along Route L/R and hover. c. Enable Continuous Smart operation mode by pressing and holding the C1 and C2 buttons simultaneously for 2-4 seconds when the aircraft is hovering at any given turning point. The Aircraft Status Indicator will turn solid purple for one second. The aircraft will then fly along Route L/R continuously. The DJI MG app will display the A-B Route. d. To exit Continuous Smart operation mode, press and hold the C1 and C2 buttons simultaneously for 2-4 seconds. The aircraft will fly to the next turning point and hover.

If GNSS signal is weak during operation, the aircraft will automatically switch to Attitude mode. Exit Smart operation mode and control the aircraft manually. When the aircraft regains a strong GNSS signal, it will automatically fly to the next turning point. If you press the A or B buttons during operation, the data for Points A and B of the current route will be erased and the aircraft will hover in place. The line spacing can be customized from 3-10 m in DJI MG. It is set to a length of 5 m by default. Even though the heading of the aircraft cannot be adjusted, use the control sticks to avoid obstacles. Refer to Manual Obstacle Avoidance for details. The aircraft automatically sprays liquid when flying forwards or backwards, and does not spray when flying left or right or when hovering.

Manual Operation Mode

Set the Operation Mode switch to M to enter Manual operation mode. You can control all the movements of the aircraft, spray liquid via the remote controller’s Spray switch/button, and adjust the spray rate via the remote controller’s Spray Rate knob/dial. Manual operation mode is ideal when the operating area is small.

Manual Plus Operation Mode

Set the Operation Mode switch to M+ to enter Manual Plus operation mode. The aircraft's' Maximum flying speed is 7m/s (customizable in DJI Assistant 2 or the DJI MG app), the heading is locked, and all other movement can be manually controlled in this mode. Press the C1 or C2 buttons on the remote controller to steer the aircraft left or right. The aircraft sprays liquid automatically when flying forward or backward, and does not spray when flying left and right. Manual Plus operation is ideal for irregularly-shaped operating areas.

1. If using the Altitude Stabilization System, elevate the aircraft to the desired altitude within the working range of the Altitude Stabilization System (2-3.5 m) before entering Manual Plus operation mode. The Altitude Stabilization System starts working automatically by maintaining the spraying distance between the aircraft and the vegetation below. Refer to Altitude Stabilization System for details.

2. Set the Operation Mode switch to M+ to activate Manual Plus operation mode.

The user needs to set the job spacing before operating the task. The job spacing is not adjustable during the operation. When using the App or remote control button to make the aircraft fly to the left or right automatically, the left and right areas of the aircraft may be in the blind area of the radar module, and obstacles cannot be detected. Users must be careful. Spray rate will be adjusted automatically according to the flying speed. Maximum spray rate, maximum flying speed, line spacing, and height above the crop can be adjusted in the DJI MG app. The aircraft cannot be controlled when using the C1 or C2 switches/buttons to steer the aircraft to the left or right. Switch to Manual operation mode in case of emergency, and the aircraft will stop flying.

GAIA 160AG-Agricultural Spraying Drone User Manual

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. Click the “Pause” button or the “End” button in the lower right corner of the App; (Note: Clicking the “End” button during A-B point work will end the job directly, and will not record the interrupted coordinate points, nor can you continue the operation.)

2. The aircraft enters the return process in any way;

3. Push the emergency stop switch / flight mode switch;

4. The remote control pitch or roll stick has a striking action;

5. Obstacles are detected and the aircraft's emergency brake enters the obstacle avoidance mode;

6. The radar module obstacle avoidance function is turned on, but the radar abnormality is detected and cannot work normally;

7. The aircraft reaches a limit value of height or distance;

8. No pesticide in working box;

9. If the GNSS signal is weak, the aircraft enters the attitude mode, exits the route operation or the A-B point operation, and records the position of the time when the last GNSS signal is good.

Ensure that GNSS signal is strong when using the Operation Resumption function. Otherwise, the aircraft cannot record and return to the break point.

Resume Operation

1. Exit the route operation mode or the A-B point operation mode by any of the above methods, and the aircraft records the interruption coordinate point.

2. After the aircraft has been operated or if the conditions for triggering the recording of the break coordinate point have been removed, the aircraft is maneuvered to the appropriate position.

3. Click the "Continue" button in the lower right corner of the app to continue.

4. Return route of the aircraft If the current position of the aircraft is in the work area, the App will pop up the option, and the user can choose to fly back directly to the break coordinate point or along the path of the vertical work route to return to the original route ( fly back to the projection point). If the current position of the aircraft is not in the work area, the aircraft directly flies back to the break coordinate point and continues the work.

5. If obstacle avoidance is required during the return procedure, users can control the aircraft forwards, backwards, left, and right. Refer to Manual Obstacle Avoidance for details.

GAIA 160AG-Agricultural Spraying Drone User Manual

Typical Applications

In Smart operation mode or F-mode, users can control the aircraft forward, backward, left, and right, avoiding obstacles along the operation route, or in an emergency (e.g., abnormal aircraft behavior). The following instructions describe how to avoid obstacles manually:

Manual Obstacle Avoidance

1. Exit Smart Operation Mode or F-mode In the two modes, when using the control sticks to control the aircraft forward, backward, left or right (i.e., push the pitch or roll stick), the aircraft will automatically exit the current mode, pause the task and record the current position as a breakpoint (Point C), then complete the corresponding flight behavior and hover.

When pushing the control sticks to exit Smart Operation mode, the aircraft will need a braking distance. Ensure that there is a safe distance between the aircraft and any obstacles.

2. Avoid an Obstacle After switching to Manual operation mode, users can control the aircraft to avoid the obstacle from Point C to D.

3. Resume Operation Enter the corresponding mode, and then tap Resume in the DJI MG app. If the aircraft is in the operating area, there will be a prompt in the DJI MG app. Select Fly to Project Point. If the aircraft is out of the operating area, it will return straight to the breakpoint and resume the operation.

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 fly 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.

GAIA 160AG-Agricultural Spraying Drone User Manual

Data Protection

In the route operation and A-B point operation mode, the user can suspend the operation midway and disconnect the power supply of the aircraft to replace the battery or add pesticide. The job progress, the A and B coordinates of the history record, and the break coordinate point recorded by the job recovery function will be saved. After the user reconnects the aircraft power, the operation can be continued according to the “job recovery” procedure.

Empty Tank Warning

Profile

If using the DJI Delivery Pump, when the spray tank is empty, the aircraft will move according to the current operation or flight mode and will ascend 3 m* and hover (Smart or Manual Plus operation mode), or hover in place (Manual operation mode or F-mode). * The feature for hovering at 3 m must be enabled in DJI Assistant 2 or the DJI MG app. If not enabled, the aircraft will hover in place at its current altitude and position until you manually control it.

Using the Empty Tank Warning

1. The App prompts that there is no medicine and the aircraft will automatically close the nozzle to stop spraying.

2. Make sure the aircraft is in manual mode, maneuver the aircraft to land and turn off the motor, then add the medicine to the work box and tighten the cover of the work box.

3. Perform the mast action takeoff in manual mode. Fly the aircraft to the appropriate position and then enter the desired mode to continue the operation.

Return to Home (RTH)

Home Point: The default Home Point is the first location where your aircraft received strong GNSS signals that are required for positioning. The Aircraft Status Indicator will blink several times after the Home Point has been recorded. RTH: The Return to Home (RTH) function brings the aircraft back to the last recorded Home Point. When using System Data Protection, the Home Point will not be updated if you restart the aircraft after changing the battery.

There are three events that will trigger RTH procedure: Smart RTH, Failsafe RTH and Low Battery RTH.

Smart RTH

Press and hold the RTH button on the remote controller when GNSS is available to enable Smart RTH. Both Smart and Failsafe RTH use the same RTH procedure. With Smart RTH, you may control the aircraft’s speed and altitude to avoid collisions when returning to the Home Point. The Aircraft Status Indicator will show the current flight mode during RTH. Press the Smart RTH button once to exit Smart RTH and regain control of the aircraft.

Failsafe RTH

Failsafe RTH must be enabled in the DJI Assistant 2 or DJI MG app. If Failsafe RTH is not enabled, the aircraft will hover in place when the remote controller signal is lost.

GAIA 160AG-Agricultural Spraying Drone User Manual

Failsafe RTH activates automatically if the remote controller signal is lost for more than three seconds, provided that the Home Point has been successfully recorded, the GNSS signal is strong (white GNSS icon), and the compass is working normally. Users can interrupt the Return to Home procedure and regain control of the aircraft if the remote controller signal is recovered. Press the RTH button or toggle the RTH switch on the remote controller once to cancel RTH.

RTH Illustrator

Low Battery RTH

The low battery RTH or critical low battery landing is triggered when the LiPo battery voltage is low.

The Low Battery RTH is disabled by default. The Flight Status Indicator will blink red slowly when battery voltage is low. RTH or landing can be set in the DJI Assistant 2 or the DJI MG app. Control the aircraft through the remote controller during RTH or landing if the remote controller signal is strong. Users can set the threshold of both low battery and critical low battery levels in the DJI Assistant 2.

When battery voltage is low, motor output may be not enough for flight. Users are advised to land the aircraft immediately. Otherwise the aircraft will crash leading to damage or other dangers. The flight control system will automatically determine whether the battery voltage is adequate based on the current aircraft altitude and its distance from the Home Point. (Refer to the Figure 5 and 6 in “Failsafe Illustration” for RTH action.)

1. The Flight Status Indicator slowly blinks red if the battery voltage is low. The low battery RTH will be triggered. Users can change the settings to LED blinking only or hovering in the DJI Assistant 2.

2. The Flight Status Indicator quickly blinks red if the battery voltage is critical low. The critical low battery land will be triggered. The aircraft will begin to descend and land automatically which cannot be cancelled. Users can change the settings in the DJI Assistant 2 so that the aircraft will not automatically descend and land when the Flight Status Indicator LED blinks red.

Update Return Point

During the flight, the return point can be updated via the DJI MG App. There are two options for updating your return point:

1. Use the current position of the aircraft as the return point.

2. Use the current position of the remote control as the return point.

GAIA 160AG-Agricultural Spraying Drone User Manual

When using the built-in GNSS module of the remote control for the relevant return point setting function, please try to ensure that the GNSS module (the position with the DJI mark) is unobstructed and there are no tall buildings around it.

Follow the steps below to update your return point:

1. Run DJI MG App to enter the job interface.

2. Click××× > to select “ ” in the return point setting, and the current coordinates of the aircraft will be updated to the return point.

3. Tap ×× ×> to select “ ” in the return point setting, and the current coordinates of the remote will be updated to the return point.

4. After the return point is set successfully, the aircraft status indicator will flash green.

RTH Safety Notices

The aircraft cannot avoid obstacles during RTH. Users can only control the speed and altitude of the aircraft. Before each flight, 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.

If the aircraft is flying under 15 meters and RTH (including Smart and Failsafe RTH) is triggered, the aircraft will first 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.

The aircraft automatically descends and lands if RTH is triggered when the aircraft flies within a 5 m radius of the Home Point.

The aircraft cannot return to the Home Point when GNSS signal is weak 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.

Attitude Control When One Motor Output Fails

For 6-rotor and 8-rotor, the flight control system can control the aircraft’s attitude when one motor fails:

1. During flight, the aircraft with this flight control system is attitude controllable when one motor output fails.

2. The motor will not start before take-off. (DJI Intelligent ESCs are required for communication.)

GAIA 160AG-Agricultural Spraying Drone User Manual

Propulsion System Protection

Low voltage and overweight aircraft warnings are provided.

Altitude Stabilization System

Profile

To ensure that the spray is evenly dispensed, the aircraft uses the radar module on the Altitude Stabilization System to maintain the same distance above the crops at all times.

Radar Module

Users can use one radar module to mount under the aircraft for a fixed height. Three radar modules can also be installed in the front, rear and lower directions of the aircraft respectively, and the front and rear radar modules can predict the terrain and better simulate the flight. The radar function can be turned on or off in the app. If enabled, the fixed/predictive function is automatically enabled in the route mode, AB-point mode and enhanced manual mode. In the manual mode, the radar module can measure the altitude, but the aircraft cannot fly in a fixed altitude by using the measurement data.

How to Use

1. Make sure that the radar function is turned on in the App.

2. Enter the desired operation mode and set the relative crop height in the App.

3. After starting the operation, if the working conditions of the radar module are met, the aircraft will always maintain a relative height to the crop when it is flying.

The Altitude Stabilization System will only maintain a fixed distance from vegetation within its working range. There are large height differences (> 1m) in vegetation (i.e. nearby ditches or ponds, above sparse trees or shrubs, terraced fields). 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.

The radar status will be prompted in the DJI MG App. Users should always pay attention to the prompt information. If an exception occurs, please fix it in time.

High-precision radar obstacle avoidance module (optional)

Overview

The high-precision radar obstacle avoidance module uses microwave ranging technology to realize obstacle sensing, and can adapt to harsh working environments such as dust and spray, and supports night work. The obstacle avoidance module can sense obstacles within 30 m of the front or rear according to the flight direction of the aircraft and display corresponding information in the DJI MG App to improve the safety of the plant protection operation.

GAIA 160AG-Agricultural Spraying Drone User Manual

The built-in stabilization gimbal ensures that the radar detection angle is not affected by the attitude change of the aircraft, and at the same time, the front or rear obstacle detection is switched according to the front or rear flight of the aircraft.

Use App settings

After ensuring that the obstacle avoidance module is installed correctly, turn on the remote control and connect the aircraft to the power supply. Go to the app's homework interface > > and make sure that the obstacle avoidance feature is turned on.

Aircraft action

1. During the flight, if an obstacle is detected in the detection range 6 meters away from the aircraft, the aircraft will decelerate and then hover approximately 6 meters from the obstacle.

2. During the flight, if an obstacle is detected within the detection range within 6 meters from the aircraft, the aircraft will immediately brake to hover. The complete stopping of the aircraft requires a certain braking distance. In this case, the user should always pay attention to the distance between the aircraft and the obstacle. If necessary, the aircraft can be operated to fly in the opposite direction to avoid collision.

3. If the aircraft is in line operation or A-B point mode, the aircraft pauses the current task and records the break coordinate point during deceleration. After the user manipulates the aircraft to bypass the obstacle, the job can be resumed.

2. Only fly 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 flying near obstacles, crowds, animals, trees, and bodies of water.

4. Avoid flying 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 system cannot operate in P or F-mode within the earth’s polar regions.

Flight Limits and No-Fly Zones

Users can set flight 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, flight 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-fly zones work together to monitor flight. 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 DJI Assistant 2 or the DJI MG app. nce complete, your aircraft will fly in a restricted cylinder that is determined by these settings. The tables below show the details of these limits.

4. The Flight Status Indicator shows the current flight mode when calibration is complete. If the Flight Status Indicator blinks red, repeat the steps above to recalibrate the compass.

GAIA 160AG-Agricultural Spraying Drone User Manual

Using DJI MG (Datalink 3 is required): Tap the Aircraft Status Bar in the Operation View of the DJI MG app and select Calibrate in the Aircraft Status List, then follow the on-screen instructions.

The DJI MG app will prompt you to calibrate the compass if needed. The prompts will disappear after successful calibration.

When to Recalibrate

1. When compass data is abnormal, and the Aircraft Status Indicator is blinking red and yellow.

2. When flying in a new location, or a location that is different from your last flight.

3. When the mechanical structure of the system has changed, i.e. the mounting position of the compass has changed.

4. When severe drifting occurs in flight, i.e. the aircraft does not fly in a straight line.

Flow Calibration

When spraying for the first time, be sure to perform flow calibration, otherwise it will seriously affect the operation. Always use the measuring cup in the package for water injection to ensure accuracy. The entire calibration process takes approximately 6 - 14 minutes, please be patient.

1. Preparation before calibration: Exclude pipe air (if it is excluded, flow calibration can be performed directly) ×(1) Add approximately 2 L of water to the work box. ×(2) 2 Turn on the remote control and connect the aircraft to the power source. ×(3) Open the four pressure relief valves, short press the remote control spray button to turn on the spray until the air in the pipe is exhausted*, then close the pressure relief valve and stop spraying. * If the air cannot be removed for a long time, completely unscrew the pressure relief valve cover to remove it, and drain the air before replacing the cover.

2. Flow calibration ×(1)×level gauge calibration Add approximately 1 L of water to the pesticide tank. Go to the App's job interface, click > , and click the “Calibrate” button on the right side of the flow.

GAIA 160AG-Agricultural Spraying Drone User Manual

In the pop-up menu, select “Nozzle Model” (recommended to use the nozzles listed in the menu, otherwise the calibration may be biased), then click “Start Calibration”, the aircraft will automatically spray until the App prompt to enter the liquid pump L calibration. ×(2)×liquid pump L calibration Accurately measure 1 - 5 L of water using a measuring cup and add it to the pesticide tank.

Enter the amount of water in the pesticide tank on the App. It is important to ensure that the actual amount of water is the same as the input value, otherwise the calibration will be biased. Click “Start Calibration” and the aircraft will automatically spray to the App to enter the liquid pump R calibration. ×(3)×liquid pump R calibration Same as the liquid pump L calibration procedure. App prompt Pump R calibration is complete, wait for a while until the App prompts “Flow Calibration Complete” and the entire calibration process is complete.

3. Perform the steps to remove the duct air again and then start the normal spray operation.

During the calibration process, click > to cancel the calibration. The flow accuracy is the data before this calibration.

Need to recalibrate

1. Replace the nozzles of different models. Note: After replacing the nozzle, you need to select the corresponding nozzle in the App option. Enter the operation interface, click > to select the nozzle model.

2. Replace the liquid with different consistency.

3. After the first task is completed, the error between the actual working area and the theoretical working area is more than 15%.
