How we picked these items
We kept only steps that a rule, a maker's manual or a federal guideline actually asks for. FAA items come from 14 CFR Part 107 and Part 89. Drone steps come from the DJI Matrice 4 Series manual. Rover and base steps come from the NGS User Guidelines for Single Base Real Time GNSS Positioning and Emlid's Reach RS3 docs. If your own receiver or drone manual says something different, follow your manual.
The DJI Pilot 2 list uses menu names from the Matrice 4 manual. Other DJI Enterprise drones that use DJI Pilot 2 have the same RTK menu, but check your model's manual.
Accuracy classes on the rover list
The rover list quotes two NGS accuracy classes. RT3 is typical for topo and stakeout work: about 0.04–0.06 m (1.6–2.4 in) horizontal. RT2 is tighter: about 0.02–0.04 m (0.8–1.6 in) horizontal, and asks for a repeat shot at a different time of day. NGS gives these as 95% confidence numbers measured from the base.
