Radio Schematic
The Phantom can be flown in different modes. These modes can be selected by using the
flight mode switch on the top left of remote control. A brief description of each mode is
provided below: (for other modes, refer to the Dji Phantom Manual)
P-Mode : This mode allows for fully autonomous flight including taking off and landing. The
Phantom automatically takes off when the “Start mission” . The Phantom will fly along a
predefined mission path which is setup on and downloaded from the Ground Station. Once
the mission is completed the phantom will automatically land where it took off from.
Return to Launch: This mode automatically flies the Phantom back to its launch location
where it will land automatically.

Calibrations
Dji Phantom 4 - Compass
•Compass Calibration Procedures
•Choose an open area to carry out the following procedures.
•Ensure that the compass is calibrated. If you did not calibrate the compass as part of your pre-flight preparations, or if you have
moved to a new location since the last calibration, tap the Aircraft Status Bar in the app and select “Calibrate”, then follow the on-
screen instructions.
•Hold the aircraft horizontally and rotate 360 degrees.
The Aircraft Status Indicators will display a solid green light.
•Hold the aircraft vertically, with nose pointing downward, and
rotate it 360 degrees around the center axis. Recalibrate the
compass if the Aircraft Status Indicator glows solid red.

Calibrations
Dji Phantom 4 - IMU
•Choose a very flat surface for the Phantom 4 IMU calibration (very important)
•Remove the propellers before you start the compass calibration
•Have your batteries fully charged in the Phantom 4 quadcopter, the Remote Control and your tablet of smart cellphone
•Next, start up the Phantom 4 Remote Controller
•Start the DJI Go App
•Start up the Phantom 4 quadcopter
•In the DJI Go App, click on the “Camera” settings
•Up in the left hand corner, click on the little quadcopter (attitude) button which is the main settings page
•Scroll down and click on the “Advanced Settings”
•Click on “Sensors”
•Click on “IMU Calibration”
•Click on “Start Calibrating”
•A popup message will appear saying “Calibration Requires Approximately 5 Minutes. Do Not Move Aircraft During
Calibration”
•Click Ok and the IMU calibration will start
•Then next page will show you the IMU calibration progress. Stay on this page during the Phantom 4 IMU calibration.
•When the calibration reaches 100%, a popup message will appear stating “Calibration Complete. Restart Aircraft”
•Click ok
•Power down and then restart the Phantom 4 to complete the calibration process
•You will need to power down the Phantom 4 again and then put back on the propellers

Flight Controls (Manual Mode)
It is important to learn to fly the Phantom in Manual mode.
During any automated flight, the pilot should be ready and able
to take manual control if required.

Led Status and Battery level

Charging the Batteries
Notes
• You must fully charge the battery before your first flight
• Always turn off the battery before inserting it or removing it from the Phantom 4
• Never insert or remove the battery when it is active
Charging the Battery
• Connect the Battery charger to a power source
• Open the protection cap and connect the Intelligent Flight Battery to the Battery
Charger
• The Battery Level Indicator (LEDs) will display the current charge level
• The battery is fully charged when all of the LEDs have turned off
• Air-cool the battery after each flight, allowing it to reach room temperature before
storage
Notes
• Batteries must be charged using a DJI approved adapter (warranty will be voided if a
non-DJI charger causes issues)
• Wherever possible, don’t leave the battery unattended during charging

Flight Procedure
1. Plan a mission on the Aerobotics Mission Planner app.
2. Choose an appropriate place to takeoff and land. This area should be free of obstacles and near the highest
point of your mission.
3. Switch on your remote control (Press the power button briefly, press it again and hold it until it powers on).
4. Install the battery (fully charged)
5. Turn on the Phantom (Same procedure remote control).
6. Connect your ground station (tablet) to the remote control using the supplied usb cable.
7. Plug in the battery to the Multispectral camera.(wait for the green light on the sunshine sensor)
8. Double press the button on the Multispectral camera to start taking pictures.
9. Press the Start button on aerobotics app..
10.The phantom will automatically take off
11. Monitor the mission from the ground station.
12. Once the mission is completed the Phantom will return home and automatically land and disarm
13.Stop the mapping camera and unplug
14.Upload data. This can be done after multiple flights.

Planning an Autonomous Mission with!
Aerobotics Mission Planner

Planning an Autonomous Mission
Open the Aerobotics Mission Planner App on your
tablet. Sync you Aeroview Boundaries to the flight App
Select a block you want to fly by tapping on it, to fly a bigger
Boundary, select multiple blocks.
Generate Mission by tapping the Generate Mission
Button

Planning an Autonomous Mission
To draw a custom mission tap on the “pen icon”, and draw
the custom boundary with your finger.
Once your finger is released it will generate a boundary,
usually not following the blocked needed to fly.
Adjust the boundary by holding onto the blue markers and
drag them where best suited. To save custom mission, tap on the save button in flight
parameters.

Planning an Autonomous Mission
Once it says “Ready to Go(good)” Click Start, and the drone
will automatically Take off, Fly the Mission, Return and
then Land.
To access the parameters, click on the mission icon
Recommended Flight Paramters:
1. Camera Type: Select Drone Type
2. Hatch Angle: Boundary Dependent(See next Picture)
3. Flight altitude: 80m -120m Crop age dependent
4. Overlap: 70%
5. Sidelap: 75%
6. Flight Speed: 9m/s - 12m/s Height dependent
Hatch Angle is dependent to the Boundary. Adjust the hatch
until the flight path is parallel to the longest sides of the
boundary.

Planning an Autonomous Mission
To delete a mission, tap on the “delete mission” icon.
Telemtry icons in order from the left. Battery percentage, flight
mode, radio signal strength, distance from home, altitude and gps
status.

Ensuring Correct Overlap: Take off from near highest point
Do NOT take off from the low part
of your mission.
This will reduce overlap between
images where the terrain is higher
than takeoff point.
Take off from near the highest
part of your mission.
This will increase overlap as the
terrain gets lower than the takeoff
point.
Getting the correct overlap of the images is important to ensure successful data processing. Aerobotics requires at least
75% overlap and sidelap (set through the mission planning app). However, this overlap is set relative to your takeoff
point, thus where you take off from is important.

Extreme Cases: Steep slopes
If you are worried about lower resolution imagery when flying steep slopes, break the mission up into separate flights
with different takeoff points.
When flying areas of steep slopes, it is best to fly along the contour of the slope.
