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.

The augmentation systems: SBAS and QZSS can be enabled only if GPS operation is configured.
Galileo is not enabled as the default configuration.
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.
