STMicroelectronics Teseo-LIV3FL

Tiny GNSS low power module

The Teseo-LIV3FL module is an easy to use global navigation satellite system (GNSS) standalone module. It embeds the Teseo III single die standalone positioning receiver IC working simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS). The Teseo-LIV3FL modules bring the proven accuracy and robustness of the Teseo chips within everyone's reach. The embedded firmware and the complete evaluation environment save development time. The compactness and economy of this solution make it ideal for multiple applications.

Teseo-LIV3FL contains compensated crystal oscillator (TCXO) and a reduced time to first fix (TTFF).
