Description

The M9N GPS uses multi-constellation GNSS powered by u-blox M9N, a concurrent GNSS receiver that can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture, all four major GNSS constellations, GPS, Galileo, GLONASS, and BeiDou, can be received concurrently.

It also comes with the IST8310 compass, tricolored LED indicator, buzzer, and a safety switch. There are 3 different connector options for different purposes. This module ships with a baud rate of 115200 (38400 previously).

The high-gain 25 x 25 mm2 patch antenna provides excellent performance, and the omnidirectional antenna radiation pattern increases flexibility for device installation. It features active circuitry for the ceramic patch antenna and a rechargeable backup battery for warm starts.
