STMicroelectronics (ST), Europe's leading chipmaker has launched its new GNSS product offering, the Teseo-LIV3R ROM-based module, which the company says is a competitively-priced module that comes with ST’s full GNSS algorithm capability for cost-conscious tracking and navigation devices.
The new GNSS module features odometer functionality with three trip counters and reached-distance alert, along with geo-fencing capabilities with up to eight configurable circles and crossing-circles alarm. The chipmaker will also provide support for real-time assisted GNSS with free server access, which it says will ensure uninterrupted positioning data for dependable navigation.
The simultaneous tracking of GPS, Glonass, Beidou, and QZSS constellations, with Satellite-Based Augmentation System (S-BAS) and RTCM V3.1 differential positioning ensures excellent accuracy to within 1.5 meters (50% CEP). Tracking sensitivity of -163dBm and time-to-first-fix faster than one second ensure high performance for demanding applications. The module is easy to use and responds to proprietary NMEA commands.
With scalable power consumption according to accuracy, average current, and frequency of fixes, a sub-15µA standby mode with RTC backup, and support for multiple low-power modes, Teseo-LIV3R is suited 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.
To enable accelerate new-product development, the module is FCC certified and is supported by the STM32 Open Development Environment. STM32 applications for advanced geo-location, 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.
