- 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.

Use tutorial
Connect to V5+
Please connect it to the flight control CAN1 / CAN2 interface (CAN1 is recommended)
The connection of other PIX flight controllers is the same.
Autopilot parameter settings
You need to set flight control parameters to enable Neo 3 pro; there are different setting methods according to the flight control firmware.
ArduPilot firmware
Set the following parameters in all parameter tables of Mission planner and restart after writing
CAN_P1_DRIVERset to 1.CAN_P2_DRIVERset to 1.NTF_LED_TYPESset to 231.GPS_TYPEset to 9.
