The M9N GPS uses a multi-constellation GNSS powered by M9N, a parallel GNSS receiver that can receive and track multiple GNSS systems.All four major GNSS constellations (GPS, , GLONASS and BeiDou) can be received simultaneously thanks to the multi-band RF front-end architecture.It also comes with an IST8310 compass, a tri-color LED indicator, a buzzer and a safety switch. There are 3 different connectors to choose from for different uses. The module has a baud rate of 115200 (previously 38400).It has an active circuit for the ceramic patch antenna, a rechargeable backup battery for hot start.The high-gain 25 x 25 mm2 patch antenna provides excellent performance, and the omnidirectional antenna radiation pattern increases the flexibility of device installation.
