The Teseo-LIV3R ROM-based module provides GNSS algorithms for tracking and navigation devices, along with odometer features such as geofencing, three-point trip meters, and distance alerts.

STMicroelectronics announced on the 18th that it has added the Teseo-LIV3R ROM-based module to its GNSS product line.
The new product brings ST's GNSS algorithm capabilities to cost-sensitive tracking and navigation devices.

ST's new GNSS module offers odometer functionality, including three trip counters and distance reached alerts, along with geofencing capabilities with up to eight configurable circles and crossing circle alarms.

Real-time GNSS support with free server access ensures reliable navigation with uninterrupted positioning data.

Simultaneous tracking of GPS, GLONASS, Beidou, and QZSS satellites with S-BAS (Satellite-Based Augmentation System) and RTCM (Radio Technical Commission for Maritime Services) V3.1 differential positioning, achieving 1.5 meters (50% CEP (Circular Error Probability))y)) ensures accuracy within .

Additionally, a tracking sensitivity of -163 dBm and a fast Time-to-First-Fix (TFF) of less than 1 second ensure high performance even in demanding applications. The module is easy to use and can also respond to proprietary National Marine Electronics Association (NMEA) commands.

Teseo-LIV3R is suitable for battery-sensitive applications because it supports sub-15µA standby mode and multiple low-power modes with RTC backup, along with scalable power consumption based on accuracy, average current, and data acquisition frequency.

Low-power modes include continuous position fixes in adaptive and power-saving cycled modes, periodic position fixes using GPS only, and on-demand position fixes for devices in permanent standby.

The new module has received FCC certification to simplify and accelerate new product development and is supported by the STM32 Open Development Environment.

STM32 applications for advanced geolocation and smart tracking, server-assisted GNSS, are available, and hardware development time is accelerated with the EVB-LIV3x evaluation board and X-NUCLEO-GNSS1A1 expansion board.

The Teseo Suite PC tool allows for easy configuration and fine-tuning of performance. Developers can join the ST GNSS community to share information and enhance field understanding.

The Teseo-LIV3R module is currently sampling as a 9.7mm x 10.1mm LCC18 module, with pricing starting at $7.30 for orders of 1,000 pieces.
