1.5 Supported GNSS Constellations

The MAX-M8 GNSS modules are concurrent GNSS receivers that 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 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. QZSS, IMES and SBAS, GAGAN

augmentation systems share the same frequency band as GPS and can always be processed in conjunction with

GPS.

The module can be configured to receive any single GNSS constellation or within the set of permissible

combinations shown below.

Table 2 Permissible GNSS combinations (• = enabled)

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 MAX-M8 positioning modules are designed to receive and track the L1C/A signals provided at 1575.42 MHz

by the Global Positioning System (GPS). The MAX-M8 series can receive and process GPS concurrently with

GLONASS or BeiDou.
