How To Use DJI D-RTK2 Base Station As GNSS Rover (Network)

Introduction


The purpose of this document is to show our users how to connect to a custom network with the D-RTK 2 to acquire latitude, longitude, and height.

What You Will Need

  1. D-RTK 2 on firmware v02.02.0014 or later.
  2. Phantom 4 Remote Controller with GSR application on firmware v02.02.0014 or later. (Make sure the RC has an empty micro SD card inserted.)
  3. USB type C cable
  4. PC


Handheld RTK Mode with NetworkRTK

1: From the main page of the GSR application, select settings (three lines at the top left). If your controller is already connected to the D-RTK 2 in handheld mode skip to step 8






2: Select device management and select “D-RTK 2 handheld Stick” mode.





3: Select “Linking






4: Select “Handheld Stick + Walk with Network RTK”. The RC will need to remain connected to the Internet.





5: Follow the onscreen instructions for turning on the D-RTK 2.





6: Follow the onscreen instructions to change to handheld stick mode.






7: Follow the onscreen instructions for linking the D-RTK 2 to the  remote controller.






(Press the linking button on D-RTK 2. Once linking is complete the device will restart.)





8: Enter your NTRIP host, port, user, password, and mount point information. 

   Please note, this is typically a paid service. 

When setting the mount point check with your service provider to determine the closest Virtual Reference Station (VRS) relative to your location. As an example, the mount point may be in the following format.


VRS_correction format; example: XXX_RTCM3



9: In the main page of the GSR application, select “Fly” and check the RTK status by selecting “RTK” located at the top of the user interface.





Make sure RTK is well connected. The “Position” status has three options:

  1. None – no connection
  2. Float - meter accuracy
  3. Single - decimeter accuracy
  4. Fix - centimeter accuracy


10: Scroll down to the RTK diagnosis and confirm the GSR application is connected to the custom network RTK.




11: To get the coordinates:


1） Within the GSR App mission planning section select “Walk with handheld RTK”




  1. In this page you’ll find the following displayed:
  1. Handheld RTK positioning in degree, minute, second format and standard deviation following the sigma symbol.
  2. Handheld RTK Status
  3. RTK Signal strength and the custom network RTK service signal strength.
  4. Task list
  5. Position




  1. Click Set Point, There will be two options available when a point is set.
  1. Current Coordinate：This will record one time positioning
  2. Average Coordinate Value：This will record 5 times within 2 seconds and take the average




  1. Click C2 or tap on the screen where it has the C2 point Setting. Make sure not to move the D-RTK 2 when the point is being recorded.






  1. Measure and set the D-RTK 2 height to the top of its antenna. Label your point accordingly and select "save".




  1. The point saved will be displayed.




  1. Enter a task name to save your known points.



12: Check the task list to view all available  tasks or to confirm your task has been saved.




13: From the main page, export the data from the SD card icon and open the drop down menu.





14: From the drop down menu select "Export Handheld DRTK Point Task".




15: Select the dataset to export.





16: The data will be available in the following folder /DJI/ EXPORT/RTK_SCOUT/ directory.
17: Connect to the Phantom 4 RTK Controller using a USB-type C cable to a computer. Select the USB icon located at the top left or drag down from the top to copy files to your computer




18: Turn on USB Storage, the device will appear on your computer. Open the following directory to download the files: /DJI/EXPORT/RTK_SCOUT/





19: The data files will be stored in text format. Follow the steps in the instructions to convert data from text to a CSV file.


Go to the following website:

https://json-csv.com/ or http://www.convertcsv.com/json-to-csv.htm


2


Upload JSON File

  1. Upload.txt data file to the website 3） It will atomically convert to CSV file



The data set above includes： Index：PTS No.

Altitude (Unit: meter) Antenna Height (Unit: meter) Latitude （Unit: Degree） Longitude (Unit: Degree) StdAlt (Unit: cm)

StdLat (Unit: cm) StdLon (Unit: cm)
