The STMicroelectronics Teseo-LIV4F GNSS module leverages ST’s Teseo IV single-die receiver technology, including L1 and L5 frequency-band support, to provide positioning accuracy better than one meter in embedded geolocation systems.
With an ultra-compact form factor and low power consumption, Teseo-LIV4F also extends multi-constellation compatibility to include navigation with Indian constellation (NavIC or IRNSS, the Indian Regional Navigation Satellite System).
The modules come with Teseo-LIV4FSW firmware, allowing users to leverage the Teseo Suite PC-based application for free firmware configuration and updating. The proven evaluation environment saves development time, while the small module size and low cost make the Teseo-LIV4F ideal for a wide variety of position, navigation, and timing (PNT) applications. These include insurance, goods tracking, tolling, anti-theft systems, people and pet location, vehicle tracking, emergency calls, fleet management, vehicle sharing, diagnostics, and public transportation.
With an on-board temperature-compensated crystal oscillator (TCXO) and dedicated real-time clock (RTC) oscillator, the Teseo-LIV4F delivers superior accuracy and fast time to first fix (TTFF). It also provides real-time assisted GNSS that allows prediction of satellite data based on previous observations. Operating with 49mA GNSS L1 and L5 tracking current and 10μA standby current extends battery runtime in power-conscious applications. Tracking sensitivity of -162dBm helps maintain accuracy when signal strength is low.
The Teseo-LIV4F module is officially certified in accordance with CE, FCC, and ICES regulations, which simplifies the path to market for the final application. The operating temperature range from -40° to 85° C permits use in harsh environments such as outdoors and in factories.
The Teseo LIV4F is in production now, in a 9.7 x 10.1 mm LCC-18 pin package and is covered by ST’s extended product-longevity assurance for industrial ICs.
