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.
Nice to be able to use other batteries in field, but cautious because of the failure, I’ve decided to use only on freestyle type flying where recovery is possible, but I don’t use it over water etc because it can’t be trusted now
