Product details
Overview
TESEO-LIV4FTR from STMicroelectronics is a standalone dual-band GNSS module integrating the Teseo IV single-die receiver IC, supporting simultaneous GPS/Galileo/GLONASS/BeiDou/QZSS and IRNSS-ready operation. It delivers submeter horizontal accuracy (CEP 50%, 24h static), -162 dBm tracking sensitivity with external LNA, 10 Hz max fix rate, and operates from -40 °C to +85 °C in a 9.7 × 10.1 mm LCC-18 package - deployed in vehicle tracking, fleet management, and emergency call systems.
For engineers reviewing the TESEO-LIV4FTR datasheet, TESEO-LIV4FTR pinout, TESEO-LIV4FTR application, or TESEO-LIV4FTR equivalent, key selection considerations include its real-time assisted GNSS (RT-AGNSS) capability, embedded TCXO for <1.5 s hot TTFF, dual UART/I²C NMEA interface support, VCC/VBAT dual-supply architecture (3.0–3.63 V), and integrated antenna short/open-circuit detection on VCC_RF.
Technical Context
The TESEO-LIV4FTR implements a multi-constellation, multi-frequency (L1+L5) GNSS baseband engine with dedicated RTC oscillator and temperature-compensated crystal oscillator (TCXO) to minimize time-to-first-fix and stabilize tracking in weak-signal environments. Its firmware supports runtime configuration of constellation selection, SBAS (WAAS/EGNOS/GAGAN/MSAS), and RTCM v3 differential corrections.
It features two independent power domains: main digital logic (VCC) and backup domain (VBAT) enabling 10 μA standby current with RTC persistence. The RF front-end includes integrated LNA and SAW filter, with VCC_RF (pin 14) providing regulated 3.3 V antenna supply and built-in open/short-circuit detection per ETSI EN 303 413.

Applications
| Vehicle Tracking | Fleet Management |
|---|---|
Use Scenario: Real-time location logging for commercial vehicles across national borders with mixed GNSS coverage. IC Role / Device Role / Timing Role: Standalone positioning engine delivering NMEA GGA/RMC sentences over UART at 10 Hz with submeter CEP accuracy.

IC Role / Device Role / Timing Role: Raw measurement data provider (pseudorange, carrier phase) for sensor fusion with IMU and barometer. Use Value: Support for BeiDou B2a and Galileo E5a improves multipath rejection and vertical accuracy - critical for low-altitude precision landing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standalone GNSS module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| u-blox NEO-M8N-0-10 | L1-only, no L5; -160 dBm sensitivity; no embedded TCXO (requires external); 16.0 × 12.2 mm LCC-32 | Lacks dual-band resilience and submeter accuracy in challenging RF environments | Select when cost sensitivity outweighs L5 performance and board space allows larger footprint |
| Quectel L96-M33 | GPS/GLONASS only; -165 dBm sensitivity; no RTC or VBAT domain; 10.1 × 9.7 mm LCC-18 | Missing Galileo/BeiDou/QZSS limits global interoperability and SBAS augmentation (EGNOS/WAAS) | Select for legacy GPS/GLONASS-only deployments where regional coverage suffices and RTC persistence is unnecessary |
Compared with NEO-M8N-0-10 and L96-M33, TESEO-LIV4FTR uniquely combines L1+L5 dual-band, embedded TCXO+RTC, VBAT-backed standby, and full multi-constellation support - making it optimal for next-gen eCall, insurance telematics, and high-integrity drone navigation requiring submeter accuracy and fast reacquisition.

FAQ
What GNSS constellations and frequency bands does TESEO-LIV4FTR support?
TESEO-LIV4FTR supports GPS L1C/A and L5C, Galileo E1 and E5a, GLONASS L1OF, BeiDou B1i and B2a, QZSS L1/L5, and is IRNSS-ready via firmware update. It processes signals across L1 (1575.42 MHz) and L5 (1176.45 MHz) bands simultaneously, enabling multi-band, multi-constellation positioning for improved accuracy and reliability in obstructed environments.
How does the embedded TCXO and RTC improve time-to-first-fix and system reliability?
The integrated temperature-compensated crystal oscillator (TCXO) stabilizes the RF downconversion clock, reducing thermal drift and enabling -162 dBm sensitivity. Combined with the always-on RTC domain powered by VBAT, it maintains precise time and ephemeris data during sleep, achieving 1.44 s hot TTFF and ensuring rapid reacquisition without full satellite search - critical for battery-powered trackers and eCall systems.
Can TESEO-LIV4FTR operate with an active antenna, and how is antenna health monitored?
Yes - TESEO-LIV4FTR supplies 3.3 V to active antennas via VCC_RF (pin 14) and includes hardware-level open/short-circuit detection. It reports antenna status (OPEN/OK/SHORT) in real time via NMEA messages based on measured current: ≤1 mA (open), 2–40 mA (normal), >40 mA (short). This eliminates need for external monitoring circuitry and prevents damage from faulty antenna connections.
Is firmware update supported, and what tools are required?
Yes - firmware updates are fully supported using the free Teseo-Suite PC tool from STMicroelectronics. The module accepts new firmware images over UART or I²C, and supports runtime configuration changes (e.g., constellation enable/disable, SBAS region, fix rate) via standardized NMEA commands. Latest firmware (e.g., GNSSLIB_8.6.x.xx_ARM) is hosted on www.st.com with release notes and migration guides.
