STMicroelectronics is making its Teseo III satellite-navigation receiver accessible to a wider designer community by introducing the Teseo-LIV3F module, which integrates essential features to accelerate application development and also adds up to 16 Mb of Flash memory for firmware updating or data logging without a backup battery.

The Teseo III multiconstellation receiver features fast response time and low power consumption. The Teseo-LIV3F module now enables makers and small engineering teams without extensive in-house RF expertise to leverage Teseo III’s advantages in creating products in the industrial and consumer market segments like vehicle trackers, drones, anti-theft devices, pet locators and systems for services such as fleet management, tolling, vehicle sharing and public transport.

The easy-to-use, 18-pin, 9.7 x 10.1 mm module contains the Teseo III receiver with on-chip power management, UART and I²C interfaces, alongside the Flash memory, an ultrastable temperature-controlled crystal oscillator (TCXO) and 32 kHz real-time clock (RTC). The documentation and tools delivered with the module contain all the C code needed to drive the module using the STM32 microcontroller, including the use of data logging, odometer and geofencing to aid development of value-added functionality.

While simplifying application development, the product delivers high performance, including -163 dBm tracking sensitivity and 1.5 m positioning accuracy (CEP) and low-power operation (17 µW in standby mode and 75 mW when tracking). FCC and CE certifications streamline product testing and accelerate time to market.

Multiconstellation flexibility ensures robust, failure-resistant navigation worldwide, with access to GPS, GLONASS, Galileo and Bei Dou constellations, as well as the Pacific-region QZSS. The module supports assisted modes including autonomous ST Assisted GPS and Server-Based Assisted-GNSS with free server access, to retrieve ephemeris data if satellites are unavailable for fast TTFF (time to first fix). There is also support for standardised augmentation systems to enhance accuracy, including the US, European, Japanese/South-East Asia and Indian Satellite-Based Augmentation Systems (SBAS) and the Radio Technical Commission for Maritime Services (RTCM) differential GPS.
