August 1, 2023 /SemiMedia/ — STMicroelectronics lately launched the Teseo-LIV4F GNSS module, which leverages ST’s Teseo IV single-chip receiver expertise and contains L1 and L5 band assist to supply higher than one-meter positioning accuracy in embedded geolocation programs. That includes an ultra-compact type issue and low energy consumption, Teseo-LIV4F additionally extends multi-constellation compatibility, together with Indian constellation navigation (NavIC or IRNSS, Indian Regional Navigation Satellite tv for pc System).

The modules include Teseo-LIV4FSW firmware, permitting customers to leverage the Teseo Suite PC-based software totally free firmware configuration and updating. The confirmed analysis setting saves growth time, whereas the small module measurement and low price make the Teseo-LIV4F preferrred for all kinds of place, navigation, and timing (PNT) functions. These embody insurance coverage, items monitoring, tolling, anti-theft programs, individuals and pet location, car monitoring, emergency calls, fleet administration, car sharing, diagnostics and public transportation.

With an on-board temperature-compensated crystal oscillator (TCXO) and devoted real-time clock (RTC) oscillator, the Teseo-LIV4F delivers superior accuracy and quick time to first repair (TTFF). It additionally gives real-time assisted GNSS that enables prediction of satellite tv for pc knowledge based mostly on earlier observations. Working with 49mA GNSS L1 and L5 monitoring present and 10μA standby present extends battery runtime in power-conscious functions. Monitoring sensitivity of -162dBm helps preserve accuracy when sign energy is low.

The Teseo-LIV4F module is formally licensed in accordance with CE, FCC, and ICES laws, which simplifies the trail to marketplace for the ultimate software. The working temperature vary from -40°C to 85°C permits use in harsh environments corresponding to outside and in factories.

The Teseo LIV4F is in manufacturing now, in a 9.7mm x 10.1 mm LCC-18 pin bundle and is roofed by ST’s prolonged product-longevity assurance for industrial ICs.

Additionally now accessible, the Teseo-LIV4FM dual-band GNSS measurement engine module with the identical measurement and pin-out of Teseo-LIV4F gives GNSS uncooked measurements utilizing the RTCM v3 protocol. Teseo-LIV4FM addresses exact positioning functions like micro mobility, agriculture, and navigation by delivering centimeter stage accuracy utilizing the MCU-host RTK/PPP algorithm. Engineering samples of Teseo-LIV4FM can be found now. Manufacturing is scheduled for the top of 2023.
