Just got this from DJI Support. It appears to be a new draft or in-house manual documenting the use and functions of the D RTK-2, with previously un-documented methods and functionality (including "Mode 3" AKA handheld mapping use! requires the MG app).


This is clearly a pre-release version and not even available on https://www.dji.com/d-rtk-2/info#downloads yet.

Enjoy!

Just tried the Mode 3 thing and couldn't get it to link to RC after switching modes. Ran out of time, I'll try again later.

Hi patiam,

following the instructions of the draft D-RTK 2 user manual you have shared with us, after setting the D-RTK2 in mode 3, I have been able to start a "Walk with handheld RTK" session in the DJI GS RTK app. Moreover I was able to save some point coordinates.

The point now is that I am not able to find the saved data file, both in P4RTK Remote Controller and in the D-RTK2 receiver. I suppose I have to look for it into the Remote Controller internal memory or into the SD card, but I do not know how to list the memory content.
Do you have any suggestion?

Moreover, did you manage to save and dowload any RAW data (RINEX) from the D-RTK2 ?

Thanks,
Maurizio

P.S.
I have installed last firmware version (v02.02.0014).

Hi,


from what I read, it seams that the D-RTK2 Mobile Station stores the raw GNSS data (satellite observation and broadcast ephemeris ??) into RTKnnn.DAT files.  

You can find them into the following directories:
\log\rtcmraw (read the D-RTK2 internal memory as an USB storage device)
log_export (use DJI Assistant 2 for Phantom > Log Export)

The files should be in RTCM3.2 MSM5 binary format and it should be possible to convert them in RINEX format using a thrird-party tool.

I have found such info in the following document:  https://shop.quadrocopter.com/assets/images/P4RwhitePaperV2.pdf

I will furder investigate the topic and let you know.

Maurizio

Hi,

thanks a lot for sharing the link.

I agree that the best free tool for data format conversion and pos-processing are RTKlib and RTKlib demo5.

You can find useful materials in the following  web sites too:
http://rtkexplorer.com/
https://www.aerotas.com/phantom-4-rtk-ppk-processing-workflow/

I did not opened the D-RTK2 Mobile Station but I suspect that its GNSS chipset is an u-blox ZED-F9.
