NEO 3 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 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.
When you connect NEO 3 to autopilots of other brands (non-CUAV autopilots), the buzzer will not work. If you need to use it on autopilots of other brands, please select NEO 3 Pro.
Autopilot parameter settings
Neo 3 is a plug-and-play module without parameter settings.
