The GNS41xsLP from GNS Electronics is a GNSS module that supports GPS, GLONASS, SBAS, QZSS, BeiDou and Galileo. This low-power module integrates a complete GNSS receiver enabling RF to NMEA solutions that minimize the load on the host processor. It has a GNSS tracking and navigation sensitivity of -161 dBm and consumes 22.5 mW of power with GPS 8-ch tracking. The device features an internal power-on reset circuit which enables autonomous startup without external reset control by the system.
This module contains all input circuitry needed to connect a passive GPS antenna directly to the module. Depending on the application, patch or chip antennas, or combo antennas (combination of GPS and Bluetooth) can be used. The GNS41xsLP provides standard NMEA message output from the solution to the host, where the module can be connected to the host system via a UART. This module is available in a 36-pin surface-mount package that measures 10 x 9.3 x 2 mm. It is ideal for use in in-vehicle navigation equipment, dynamic navigation, portable (“nomadic”) devices, netbooks, tablet PCs, mobile phones, precision timing via GPS logger, GPS tracker, security devices, and camera equipment.
