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.

Table 2: Permissible GNSS combinations (• = enabled)
The augmentation systems: SBAS and QZSS can be enabled only if GPS operation is also configured.
Galileo is not enabled as the default configuration.
BeiDou reception is not supported by SAM-M8Q module.
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).
1.5.2 GLONASS
The SAM-M8Q GNSS patch antenna module can receive and process the GLONASS satellite system as an
alternative to the US-based Global Positioning System (GPS). The SAM-M8Q is designed to receive and track the
L1OF signals which GLONASS provides at 1602 MHz + k*562.5 kHz, where k is the satellite’s frequency channel
