Real-time assisted GNSS support with free server access ensures uninterrupted positioning data for dependable navigation

STMicroelectronics has enlarged its GNSS product offering with the Teseo-LIV3R ROM-based module.

ST’s new GNSS module provides odometer functionality with 3 trip counters and reached-distance alert, along with geofencing capabilities with up to 8 configurable circles and crossing-circles alarm.

Simultaneous tracking of GPS, Glonass, Beidou, and QZSS constellations, with Satellite-Based Augmentation System (S-BAS) and Radio Technical Commission for Maritime Services (RTCM) V3.1 differential positioning ensures excellent accuracy to within 1.5 meters (50% Circular Error Probability (CEP). Time-to-first-fix faster than one second ensures high performance for demanding applications.  The module is easy to use and responds to proprietary National Marine Electronics Association (NMEA) commands.

With a support for multiple low-power modes, Teseo-LIV3R is an ideal choice for battery-sensitive applications. The low-power modes include continuous-fix with adaptive and power-saving cycled modes, periodic-fix with GPS only, and fix-on-demand with the device in permanent standby.

Key Features

  • Tracking sensitivity of -163dBm
  • Scalable power consumption according to accuracy, average current, and frequency of fixes
  • Sub-15µA standby mode with RTC backup

To simplify and accelerate new-product development, the module is FCC certified and is supported by the STM32 Open Development Environment. STM32 applications for advanced geolocation, smart tracking, and server-assisted GNSS are available, while the EVB-LIV3x evaluation board and X-NUCLEO-GNSS1A1 expansion board provide a head-start with hardware.

The Teseo Suite PC tool helps easily configure settings and fine-tune performance.

Availability

The Teseo-LIV3R is in volume production. The 9.7mm x 10.1mm LCC18 module is priced from $7.3 for orders of 1000 pieces.
