Turn the Mapper On/Off
Press the power button of the mapper, then again and hold to turn it on or off. The mapper will turn off automatically if it is idle (i.e. there are no button inputs on the operation panel) for 30 minutes.
Activation
Make sure to activate the mapper using DJI ASSISTANT 2 before first-time use.

Visit the official DJI website. Download and install the latest version of the DJI Assistan software. http://www.dji.com/mg-1s/info#downloads
Turn on the mapper. Connect it to your computer via a Micro USB cable.
Run DJI Assistant 2 and click “MG-1S RTK”. Activate the device following the instructions in the pop-up window.
Restart the mapper manually after activation.

DO NOT change any of the settings in DJI Assistant 2. Use the product under the default settings.
Linking

Turn on the D-RTK Base Station. “GNSS” in the lower left corner of the screen indicates a successful start.
Turn on the mapper. “GNSS” in the lower left corner of the screen indicates a successful start.
Ensure that the upper left corner of the screen shows “BS”, which indicates Base Station RTK Mode. If it shows “RC”, press and hold the Mode button to switch to “BS”.
Press and hold the Link button on the mapper. “Linking with BS” on the screen indicates that the mapper has initiated linking.
Press and hold the Link button on the base station and it will beep for five seconds. “Linking Successful” on the screen of the mapper during beeping indicates successful linking.

If there is no device linked with the base station when beeping, it will exit linking and stop beeping automatically
Press the power button on the base station or mapper once to cancel when linking is initiated.
Linking is required only for first-time use with the same mapper and base station. The two will connect to each other automatically during future use.

Usage

Field Planning

Ensure that the mapper has adequate power, sufficient free space on the Micro SD card (max capacity 16 GB) and that it is inserted into the slot on the mapper correctly.
Press the power button once, then again, and hold to turn on the mapper.
Ensure that the upper left corner of the screen shows “BS”. If it shows “RC”, press and hold the Mode button to switch to “BS”.
Wait for initialization to complete. The lower left corner of the screen shows “GNSS” and the center shows “Ready” if RTK data is obtained and used.
Press and hold the Start/Stop Measurement button to start.
The center of the screen will show “Edge X-Y”. “X” means the recorded point number for the edge measurement and “Y” means the recorded calibration point number.
Walk alongside the boundary of the field and press the Add Waypoint button once to record a point. The corresponding number will increase by one.
If any obstacles are in the operating area, press the Obstacle Measurement button once to enter Obstacle Measurement mode. The center of the screen will show “Obstacle Z-N.” “Z” is for the recorded point number around the obstacle. Walk alongside the boundary of the obstacle and press the Add Waypoint button once to record a point. Z will increase by one. “N” refers to the Nth obstacle being measured, meaning that each time you enter Obstacle Measurement mode N will increase by one. After obstacle measurement, press the Obstacle Measurement button once to exit from the mode and continue edge measurement.
Calibration points are required to rectify measurement bias caused by the positioning difference between the mapper and aircraft. Ensure that the screen displays “Edge”. If it displays “Obstacle”, press the Obstacle Measurement button once to switch. Choose at least one fixed reference point for calibration like a metal peg or obvious marker. Then press and hold the Add Waypoint button. The mapper will beep for one second to indicate that the calibration point has been recorded.
After measurement complete, press and hold the Start/Stop Measurement button. The screen will display “Ready”.

More than one calibration point can be recorded for the field, but at least one is required. Measurement cannot be stopped by pressing and holding the Start/Stop Measurement button. The mapper will sound an alarm if no calibration point is recorded. Record at least one calibration point and then stop measurement by pressing and holding the button.
Try to keep the mapper upright and level during measurement by monitoring the bubble level. When the bubble is within the black circle, the mapper is vertical.

Importing Data
Measurement data is saved to the Micro SD card in the mapper. Export it to the remote controller for use.

After a measurement is complete, turn off the mapper. Take out the Micro SD card and insert it into the Micro SD card slot on the remote controller.
Power on the remote controller and go to the DJI MG app.
Select “Handheld RTK Task” in the pop-up box. Data in the Micro SD card will be listed and sorted by time. Select the data corresponding to the desired field and tap “Import”.
After importing, enter Operation View. Tap the Task List and sort by time. Here you can find the last imported task.
