1.5 Supported GNSS constellations

ZOE-M8 GNSS SiPs are concurrent GNSS receivers which can receive and track multiple GNSS

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

either GLONASS or BeiDou can be processed concurrently with GPS and Galileo signals, thereby

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,

GLONASS or BeiDou and disabling QZSS and SBAS. The ZOE-M8 SiPs can be configured to receive

any single GNSS constellation or any one combination from the set of permissible combinations

shown below.

1.5.1 GPS

The ZOE-M8 positioning SiPs are designed to receive and track the L1C/A signals provided at

1575.42 MHz by the Global Positioning System.
