Teseo-LIV4F GNSS modules of "1 plus 1 is greater than 4" .

Featuring an ultra-compact form factor and low power consumption, Teseo-LIV4F also extends multi-constellation compatibility, including Indian constellation navigation (NavIC or IRNSS, Indian Regional Navigation Satellite System).

The module comes with Teseo-LIV4FSW firmware, allowing users to utilize the Teseo Suite PC-based application for free firmware configuration and updates. A proven evaluation environment saves development time, while the small module size and low cost make the Teseo-LIV4F ideal for a variety of positioning, navigation and timing (PNT) applications.

The Teseo-LIV4F has an on-board temperature compensated crystal oscillator (TCXO) and a dedicated real time clock (RTC) oscillator that provide excellent accuracy and fast time to first fix (TTFF). It also provides real-time assisted GNSS, allowing satellite data to be predicted based on previous observations.

Operating from 49mA GNSS L1 and L5 tracking current and 10µA standby current extends battery run time in power-conscious applications. Tracking sensitivity at -162dBm helps maintain accuracy at low signal strength.

The Teseo-LIV4F module is officially certified under CE, FCC and ICES regulations, simplifying the path to market for end applications. The operating temperature range is -40°C to 85°C, allowing use in harsh environments such as outdoors and factories.

Application examples

The Teseo LIV4F is now in production, packaged in a 9.7mm x 10.1mm LCC-18 pin, and backed by ST's extended product lifetime guarantee for industrial ICs. Also introduced is the Teseo-LIV4FM dual-band GNSS measurement engine module with the same dimensions and pinout as the Teseo-LIV4F. It provides GNSS raw measurements using the RTCM v3 protocol.

Teseo-LIV4FM provides centimeter-level accuracy by using MCU-hosted RTK/PPP algorithms, meeting the needs of precise positioning applications such as micro-mobility, agriculture, and navigation.

Engineering samples of the Teseo-LIV4FM are available now. Production is planned for late 2023.
