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 Teseo III multi-constellation receiver combines high accuracy with 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 the Teseo III advantages in creating
new 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, or public
transportation.
The easy-to-use 18-pin, 9.7mm x 10.1mm 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 -163dBm tracking
sensitivity and 1.5m positioning accuracy and low-power operation (17µW
in standby mode and 75mW when tracking). FCC and CE certifications
streamline product testing and accelerates time to market.
Multi-constellation flexibility ensures robust,
failure-resistant navigation worldwide, with access to GPS, GLONASS,
Galileo, and Bei Dou constellations, as well as the Pacific-region
Quasi-Zenith Satellite System (QZSS). The module supports assisted modes
including autonomous ST Assisted GPS (STAGPS) 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 standardized 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.
The Teseo-LIV3F module is available now as an 18-pin LLC device.
