STMicroelectronics' Teseo-LIV4F GNSS module leverages ST's Teseo IV single-array receiver technology, including L1 and L5 frequency band support, to provide better than one meter positioning accuracy 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 the Indian constellation (NavIC or IRNSS, the Indian Regional Navigation Satellite System).
The modules come with Teseo-LIV4FSW firmware, allowing users to take advantage of the PC-based Teseo Suite application for free firmware configuration and updates. The proven evaluation environment saves development time, while the small module size and low cost make Teseo-LIV4F ideal for a wide variety of position, navigation and timing (PNT) applications. This includes insurance, merchandise tracking, tolls, anti-theft systems, tracking people and pets, vehicle tracking, emergency calls, fleet management, car sharing, diagnostics and public transport.
With an integrated temperature-compensated crystal oscillator (TCXO) and a dedicated real-time clock oscillator (RTC), the Teseo-LIV4F offers superior accuracy and fast time to first correction (TTFF). It also provides real-time assisted GNSS that allows forecasting of satellite data based on previous observations. Operating at 49mA GNSS L1 and L5 tracking current and 10μA standby current extends battery runtime in power-intensive applications. -162dBm tracking sensitivity helps maintain accuracy when signal strength is low.
The Teseo-LIV4F module is officially certified according to CE, FCC and ICES regulations, which simplifies the path to market for the final application. The operating temperature range of -40° to 85° C allows use in harsh environments such as outdoors and factories.
The Teseo LIV4F is in production now, in a 9.7 x 10.1mm LCC-18 package, and is covered by ST's extended product longevity warranty for industrial ICs.
