Ublox M9N Satellite receiver
It is a new generation satellite receiver based on Ublox M9N, the actual measurement can reach a maximum accuracy of 0.7m.
Simultaneous reception by the four satellite systems
It supports simultaneous reception of Beidou, Galileo, Glonas, and GPS four satellite systems. Also, it has the high-performance processing unit STM32F412 built-in and using RM3100 industrial grade sensor, has better anti-interference performance.
Triple filter design
Featuring a SAW+LNA+SAW triple‑filter design, the NEO 3 Pro effectively mitigates interference from remote‑control signals, data‑transmission signals, and 4G cellular signals for GPS positioning reception. With the SBAS augmentation system enabled, the module delivers a nominal horizontal accuracy of 1.5 m by default; this figure changes to 2.0 m once SBAS is disabled. For differential work, it accepts RTCM3.3 input but cannot output RTCM messages. The receiver supports pseudorange differential positioning for meter‑level results yet lacks carrier‑phase differential (RTK) capability, requiring a base station capable of RTCM3.3 output.
