NEO 3 GNSS Modules
NEO 3 uses a hardware design similar to NEO V2, and upgrades the GNSS navigation module to the M9N module that supports the four mainstream satellite systems of Beidou, GPS, Galileo and Glonass. The positioning accuracy has been significantly improved. It is a high Cost-effective unmanned system positioning and navigation module. It integrates compass, barometer, flight controller status light, buzzer, and safety switch in one; it has the characteristics of high sensitivity and strong anti-interference.
Features
Buzzer prompt
safety switch
CAN Bus
MS5611 Barometer
RGB Status Light
CROCOMM custom four-star high gain antenna
Ublox M9N Satellite receiver
New generation satellite receiver Ublox M9N，The actual measurement can reach a maximum accuracy of 0.7m.
Simultaneous reception by the four satellite systems
Supports simultaneous reception of Beidou, Galileo, Glonas, and GPS four satellite systems
RM3100 industrial sensor
Using RM3100 industrial grade sensor, has better anti-interference performance
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 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.
