CUAV NEO 3 GPS Module | GNSS U-blox M9N Drone Hardware

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.

Use Tutorial

Connect with V5+

Connect to [GPS&SAFETY] interface.

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.
