Miniature multi-constellation satellite navigation receiver speeds application development

September 14, 2018 // By Julien Happich
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 speed application development and also adds up to 16Mbit of Flash memory for firmware updating or data logging without a backup battery.

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 ultra-stable temperature-controlled crystal oscillator (TCXO), and 32kHz 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 geo-fencing to aid development of value-added functionality. While simplifying application development, Teseo-LIV3F delivers high performance, including -163 dBm tracking sensitivity and 1.5m positioning accuracy (CEP) and low-power operation (17µW in standby mode and 75mW when tracking). FCC and CE certifications streamline product testing and accelerates time to market.
