- NEO 3 Pro level accuracy when the SBAS enhancement system is turned on, the nominal accuracy is 1.5m (default); when the SBAS enhancement system is turned off, it is 2.0m
- NEO 3 Pro supports RTCM3.3 injection, but does not support RTCM output; it can achieve pseudorange differential (meter-level positioning) but does not support carrier phase differential (RTK), and it needs a base station that supports RTCM3.3 output.
Ardupilot 4.0.0 and above firmware supports NEO 3 PRO, and PX4 firmware is still in the adaptation stage.
