Hi everyone,


I have to do a survey and my M3E will be 20km far from the closest know point where I'll put my DRTK2


Obviously, it won't be any connection between the D RTK2 and the RC/M3E.

I would like to :

Put this D RTK2 above the know point, fly my drone, and some PPK for position corrections


Anyone would have an idea of the workflow ?

Thank you !!

Hi there, I am sorry that the distance is too far, the accuracy can not be assured. It is suggested to use it within a range of 15KM. Thank you.

Good morning,

I'm not asking you the maximum distance from the base station I can work.

I ask how we go about correcting the position of the drone when the base is too far away for it to be able to provide corrections in real time.

In other words: How to do PPK with the D RTK2

PPK or RTK, the problem is the same.  
The further the rover is from its base, the poorer the correction.  

Using PPK only removes network latency.  As DJI Susan told you, it is not recommended to use a DRTK-2 base station more than 15km away.

From experience I would even say that 10km is already a lot because at the time of doing PPK, when it will be necessary to enter the calibration of the antenna, well there is none!  

Once again, you may be using equipment that is not suited to your needs.  You still have one option, which is to place your DRTK-2 closer to the site, and PPP to find its coordinates to be able to PPK more precisely.  There is a thread about this somewhere in the pro system section.

Hi...

Thanks for your answer but again you're not answering my question.

Just looking for the technique to do PPK with the D RTK2. If it's exists.

Regards,

Ah ok you're only there.  well... you extract the RTCM3 files and then that's it.  With dedicated software (DJI doesn't make any, although Terra has a PPK function, China Mainland only) you do the rest.  

But again, when you have completed this step you will come back to what was written previously, 20km is a bit far.
