Add up to 16M bit flash memory
Firmware update possible without backup battery
Provides various support modes such as autonomous STAGPS
STMicroelectronics has launched the Teseo-LIV3F module, extending its Teseo III satellite navigation receiver to a broader designer community. The module integrates essential features to accelerate application development and adds up to 16 MB of flash memory, enabling firmware updates and data logging without a backup battery.

Highly regarded by automotive and industrial professionals, ST's Teseo III multi-constellation receiver boasts high accuracy, fast response time, and low power consumption. The Teseo-LIV3F module allows manufacturers and small engineering teams without extensive in-house RF expertise to leverage the advantages of Teseo III to develop new products for the industrial and consumer markets. That is, it is possible to develop systems for services such as vehicle management, toll collection, car sharing, and public transportation, as well as vehicle trackers, drones, anti-theft devices, and pet locators.

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

The Teseo-LIV3F simplifies application development while delivering high performance, including 163 dBm tracking sensitivity, 1.5 m positioning accuracy (CEP[1]), and low-power operation (17 µW in standby mode, 75 mW when tracking). It also simplifies product testing and accelerates time to market with FCC and CE certifications.

The flexibility of multi-constellation technology enables robust, failure-resistant navigation worldwide, with access to GPS, GLONASS, Galileo, BeiDou, and the Pacific region's Quasi-Zenith Satellite System (QZSS). The module offers assisted modes, including autonomous STAGPS (ST Assisted GPS), which provides free server access to satellite orbit data when satellites are unavailable for fast Time To First Fix (TTFF), and server-based assisted-GNSS. It also supports standardized augmentation systems to improve accuracy, including Satellite-Based Augmentation Systems (SBAS) and Radio Technical Commission for Maritime Services (RTCM) differential GPS from the United States, Europe, Japan, Southeast Asia, and India.

The Teseo-LIV3F is currently available as an 18-pin LLC device.
