Does anyone know if any TBC module can process the PPK data from the new DJI Phantom 4 RTK?

We would like to use the PPK functionality (no mobile coverage) without the DJI base station. We also don't want to purchase anymore software as we are already TBC users.

The 4 attached files prefixed 100_004 are the files from the Phantom 4 RTK. The other 2 files prefixed 'auck' are RINEX files from a nearby CORS station.

Our DJI reseller said the following about the 4 files:

  • PPKRAW has the satellite observations in RTCM3.2 MSM5 format.
  • EVENTLOG has the time log in binary
  • Rinex has the rinex observations 
  • Timestamp contains the following, in ASCI
    • 1. Photo number
    • 2. Exposure time of GPS seconds of the week
    • 3. Exposure time of GPS week
    • 4. Phase compensation between north antennae to CMOS centre (mm)
    • 5. Phase compensation between east antenna to CMOS centre (mm)
    • 6. Phase compensation between up/down antenna (downward is positive) to centre of CMOS (mm)
