1.5 Supported GNSS constellations

The SAM-M8Q GNSS module is a concurrent GNSS receiver which can receive and track multiple

GNSS systems: GPS, Galileo and GLONASS. Owing to the dual-frequency RF front-end architecture,

GLONASS can be processed concurrently with GPS and Galileo signals, thus providing reception of

three GNSS systems. By default, the M8 receivers are configured for concurrent GPS and GLONASS,

including SBAS and QZSS reception. If power consumption is a key factor, then the receiver should be

configured for a single GNSS operation using GPS, Galileo or GLONASS and disabling QZSS and SBAS.

The module can also be configured to receive any single GNSS constellation.

1.5.1 GPS

The SAM-M8Q GNSS patch antenna module is designed to receive and track the L1C/A signals

provided at 1575.42 MHz by the Global Positioning System (GPS).
