STMicroelectronics Teseo-LIV4F GNSS

Compact and powerful Global Navigation Satellite System

The STMicroelectronics Teseo-LIV4F is a compact, cost-effective, and easy-to-use Global Navigation Satellite System (GNSS) standalone low power module. This device provides superior accuracy and robustness thanks to the Teseo single die standalone position receiver IC, which works simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS).

The Teseo-LIV4F compact design measures only 9.7 x 10.1 mm without sacrificing performance. With its on-board Temperature Compensated Crystal Oscillator (TCXO) and reduced Time To First Fix (TTFF) relying on its dedicated Real Time Clock (RTC) oscillator, this device delivers superior accuracy. In addition, the Teseo-LIV4F presents a wide operating temperature ranging from -40°C to 85°C, and Real-Time Assisted GNSS, reducing time to market and making it suitable for a variety of applications.
