Anyone purchase a DJI Phantom 4RTK yet?

I would like to test a RINEX data file from this drone, for PPK.

No, but I'm experimenting with an Emlid Reach M+ GNSS mounted on the Phantom 4 using a device made by Tuffwing.  I'm using my own Trimble base and processing PPK with RTKLIB.  I had to write some custom software to correct for timing, yaw, pitch, and roll, but results are impressive.

Bill68,

  1. With RTK the Phantom 4RTK uses NTRIP for corrections, what are you using to the send the RTK corrections between the Base and Drone? This normally requires an internet connection via cell service. I'm testing if a peer-to-peer wifi connection will work from Base to Rover where there is no cell coverage.
  2. I have used 1-second epochs, recently I notice others recommended 0.2-second epoch, what EPOCH rate are you using for PPK?

I've just been post processing and recording at 5Hz.  I don't see much advantage to maintaining a real time connection.  Just something else to go wrong.
