NEO 3 Pro GNSS module

Overview

NEO 3 Pro uses a hardware design similar to NEO v2 Pro, 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.

NOTE

Ardupilot 4.0/PX4 1.13.0 and above support NEO 3Pro.

Product features

• Integrated Ublox latest generation GNSS module (NEO-M9N)
• Support the concurrency of four mainstream satellite systems to adapt to more complex environments
• Dedicated antenna supporting four major satellite systems
• UAVCAN standard protocol, high real-time, strong anti-interference
• Industrial grade sensor (RM3100), better anti-interference performance
• High-performance processing unit STM32F412
• Internal high-precision barometer to meet the needs of different application scenarios
• Open source program, support custom program
• Adopting SAW+LNA+SAW double filter design, effectively avoid 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.

Connection to V5+

• Please connect it to the flight control CAN1 / CAN2 interface (CAN1 is recommended)

NOTE The connection of other PIX flight controllers is the same.

Enable

you need to set flight control parameters to enable Neo V2 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_DRIVER set to 1.
• CAN_P2_DRIVER set to 1.
• NTF_LED_TYPES set to 231.
• GPS_TYPE set to 9.

PX4 firmware

Open QGroundControl>Parameters and modify the following parameters

• UAVCAN_ENABLESet to Sensors Automatic config .
• UAVCAN_SUB_GPS Set to Enable.
