Supported GNSS constellations Teseo-LIV3R 2 Supported GNSS constellations
The embedded FW supports the following GNSS constellations (GPS, GLONASS, BEIDOU and QZSS). The user can select what the application needs by FW configuration. GPS+GLONASS are selected by default.
2.1 GPS
The Teseo-LIV3R GNSS module is designed to receive and to track the L1C/A signals provided at 1575.42 MHz by the Global Positioning System (GPS). The Teseo-LIV3R can receive and process GPS concurrently with GLONASS or BeiDou (the last two are mutually exclusive).
2.2 GLONASS
The Teseo-LIV3R module can receive and process GLONASS concurrently with GPS. The Russian GLONASS satellite system (ГЛОНАСС; GLObal NAvigation Satellite System) is an alternative to US’s GPS.
2.3 BeiDou
The Teseo-LIV3R module can receive and process BeiDou concurrently with GPS. B1 signals provided at 1561.098 MHz by the BeiDou Navigation Satellite System can be tracked by Teseo-LIV3R positioning modules. The ability to receive and track BeiDou B1 satellite signals in conjunction with GPS results in higher coverage, improved reliability and better accuracy especially in the difficult urban environment of the big far east cities like Shanghai, Taipei, and Singapore. 8/30 DS12821 Rev 2 Document Outline Table 1.
