Tiny, dual-band, multi-constellation GNSS module for precise positioning

Easy-to-use, dual-band GNSS module for sub-meter accuracy positioning using multiple constellations simultaneously

The Teseo-LIV4F modules bring the proven accuracy and robustness of multi-band Teseo IV GNSS chips within the reach of everyone: the embedded firmware and the complete evaluation environment save development time, while the compactness and cost-effectiveness of this solution make it ideal for many applications including insurance, asset tracking, drones, tolling, anti-theft systems, people and pet location, vehicle tracking, emergency calls, fleet management, vehicle sharing, diagnostics and public transportation.

With its compact size (9.7 x 10.1 mm), the Teseo-LIV4F offers superior accuracy thanks to the on-board Temperature Compensated Crystal Oscillator (TCXO) and a reduced time-to-first-fix (TTFF) relying to its dedicated real time clock (RTC) oscillator. It also supports the real-time assisted-GNSS to reduce TTFF down to 4 seconds.

A certified solution, the Teseo-LIV4F optimizes the time to market of final applications with a temperature operating range from -40 to 85°C.
