NEO 3 Pro GNSS DroneCAN Module

Next-generation satellite receiver, u-blox M9N.
Positioning accuracy up to 0.7 meters.
Supports simultaneous reception of signals from four major satellite systems (BeiDou, Galileo, GLONASS, GPS).
DroneCAN bus communication protocol.

Ublox M9N Satellite receiver

New generation satellite receiver Ublox M9N，The actual measurement can reach a maximum accuracy of 0.7m.

RM3100 industrial sensor

Using RM3100 industrial grade sensor, has better anti-interference performance

Simultaneous reception by the four satellite systems

Supports simultaneous reception of BeiDou, Galileo, Glonas, and GPS four satellite systems

GPS

GLONASS

Galileo

BeiDou

Triple filter design

NEO 3 Pro adopts SAW + LNA + SAW triple filter design, effectively avoiding the influence of remote control, data transmission, 4G signal on GPS positioning reception.

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.
