Utilizing a Reach M2 Module as a Data Collection Device for Positioning of Ground Control Points

In short, yes. You can use one M2 with a CORS or, I would suggest two M2’s. I only have RS+ and M+'s so it may be different with the M2, but the M’s are definitely do not reach as far or deal with tough terrain as well as my RS’s. Having a base and rover is most definitely the way to go when surveying GCP’s and droning. Unless you want to take a chance that a service isn’t available or not functioning correctly. I also prefer PPK because I can verify 100% that the data I am pushing is correct whether it be good or bad. I can also adjust the correction stream after the fact in case any particular satellites or constellations had issues that day. See the thread below for the home-build I did on the Yuneec H520. The GNSS kit on it can be unmounted in about 5 seconds, the antenna tilted and mounted to a pole to act as a rover.
