Ardupilot M2 RTK post processing

Reach Module / M+ / M2 RTK / PPK configuration
1

Hi everyone, I’m using M2 on my drone. I have well intergrated M2 with Ardupilot and camera by following this tutorial: ArduPilot Integration | RTK Modules.
I would like to perform a RTK survey for my drone, what I have done is:

  • Configuring Mission Planner to inject RTK corrections (NTRIP) into telemetry
  • Configuring Reach M2 to work with ArduPilot

My question is:
Can M2 be used as RTK mapping instead of RTK navigation?
If so, what we should do to post-process the data in RTK mode? (I didn’t use a base for my flight but only NTRIP)
As in RTK mode, we don’t need to do any post-processing, which data should I use? Raw data or Position data?
How can I get corrected position of each image for geotagging?

Thanks in advance
