Supported GNSS constellations

The embedded FW supports all the GNSS constellations (GPS, GLONASS, GALIELO, BEIDOU and QZSS). The

user can select the active constellations in the firmware configuration based the applications needs; by default the

active GNSS constellations are GPS and Glonass.

2.1

GPS

The Teseo-LIV3FL 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-LIV3FL can receive and process GPS concurrently with

Galileo and GLONASS or BeiDou (the last two are mutually exclusive).

2.2

GLONASS

The Teseo-LIV3FL module can receive and process GLONASS concurrently with GPS and Galileo. The Russian

GLONASS satellite system (ГЛОНАСС; GLObal NAvigation satellite system) is an alternative to US’s GPS and

EU’s Galileo.

2.3

BeiDou

The Teseo-LIV3FL modules can receive and process BeiDou in conjunction with GPS and Galileo. The B1 signals

provided at 1561.098 MHz by the BeiDou navigation satellite system can be tracked by Teseo-LIV3FL positioning

modules. The ability to receive and track BeiDou B1 satellite signals with GPS results in higher coverage,

improved reliability, and better accuracy especially in the difficult urban environment of the significant far east

cities like Shanghai, Taipei, Singapore.

2.4

Galileo

The Teseo-LIV3FL can receive and process Galileo concurrently with GPS and GLONASS or BeiDou (the last two

are mutually exclusive).
