New GNSS Receiver
A new very-low-power multi-constellation GNSS receiver has entered the marketplace.
The 'GM' series GNSS receiver module from US company Linx is a self-contained high-performance GNSS receiver designed for navigation, tracking and positioning applications.
The 99-channel receiver can simultaneously acquire and track multiple satellite constellations, including GPS, GLONASS, Galileo and Japan’s QZSS.
The module claims exceptional sensitivity (tracking -161, cold start -143 dBm) for dense foliage and urban canyons. Hot start time is 1 s in open sky and 30 s indoors, with cold starts of 33 s or 15 s with assistance.
Position accuracy is claimed as 3 m autonomous or 2.5 m using augmentation, with time to ±11 ns. Maximum altitude is 18,000 m (~59,000 ft) and maximum velocity 515 m/s (~1,000 kt).
The very low tracking power consumption of 16 mA helps maximize run-times in battery-powered applications, and built-in duty cycling can be configured to periodically turn-off the module for further power savings.
A standard UART serial interface is used to send and receive NMEA messages in ASCII format and the receiver requires no programming or additional RF components, except an antenna.
