Overview

The TESEO-LIV3R is a compact, multi-constellation GNSS receiver module designed for simultaneous reception of GPS, GLONASS, and BeiDou signals. Operating within a wide voltage range of 2.1V to 4.3V, it features a -163dBm tracking sensitivity and a dedicated RTC for fast time-to-first-fix. This module is optimized for low-power tracking, consuming only 70mW during active tracking operations.

Why Choose This Part

The module offers a 1.5m CEP positioning accuracy and supports simultaneous multi-constellation tracking for improved reliability in urban canyons. Its embedded ARM-based architecture handles server-based assisted GNSS and includes built-in geofencing and odometer features to reduce host CPU load.

Applications

Asset Tracking
Utilizes 1.5m CEP accuracy and integrated odometer functionality for monitoring mobile equipment and logistics containers.
IoT Geofencing
Integrated geofencing support allows the module to alert the host system when a device enters or leaves a predefined boundary without constant polling.
Wearable Devices
Ultra-low standby current of 17uA and a small 9.7mm x 10.1mm LCC footprint make it suitable for battery-constrained wearable technology.
Insurance Telematics
Provides accurate positioning and distance data via I2C or UART interfaces for usage-based insurance logging systems.

Getting Started

Designers can interface with the module using standard NMEA protocols over UART or I2C. Evaluation is typically performed using the X-NUCLEO-GNSS1A1 expansion board which allows for rapid prototyping within the STM32 ecosystem. Ensure a stable 2.1V to 4.3V supply and provide an external antenna as the module does not include an integrated antenna element.
