Reach for recording GCPs

hi there,
I would like to as, how difficult would be to use Reach for recording Ground Control Points for drone photogrammetry considering I don`t have background in survey. I fly DJI so I cant use onboard rover, but being able to record GCPs with accuracy 2-5 cm would be great help for my work. Is it as simple as buying Reach RTK kit, setting all up (possibly with 3DR radio) and recording coordinates in a field? Or is some postporcess required too?

Any input would be much appreciated!


Yes, you can get such accuracy in a field with Reach RTK KIT.

For better understanding of the process you can read Reach docs.
Focus on this first part and second one.
