ST's Teseo family of Global Navigation Satellite System receiver ICs provide high positioning accuracy processing capabilities to simultaneously support multi-band and multiple global navigation systems (BeiDou, Galileo, GLONASS, GPS, Navic and QZSS).

The Teseo family of GNSS ICs includes ASIL-B compliant devices ideal for autonomous driving and advanced driver-assistance systems (ADAS) in addition to e-call and telematics systems, 5G base station timing, V2X and C-V2X as well as handheld, marine and in-car navigation systems.

Teseo GNSS receiver ICs can also provide carrier phase data to enable the use of RTK-PPP positioning algorithms on customer software or through solutions developed via the ST Partner Program.

Teseo V (STA8100GA) is the latest generation of GNSS receiver ICs, offering on-chip, multi-frequency (L1 and L5), multi-constellation, carrier-phase tracking for higher accuracy and precise positioning and autonomous position, velocity and time (PVT) calculations on a single chip.

Teseo V in conjunction with the fully integrated STA5635 RF front-end  family devices adds L2 capability as well as dual- (L1 and L2) and triple-band (L1, L2 and L5) measurement engine solutions for automotive-grade and industrial applications. Thanks to its programmable and flexible RF-IF chain driven by a fractional PLL, this solution makes it possible to manage all the GNSS constellations currently available and those planned for the near future.

TeseoAPP (STA9100) is our first ASIL-B GNSS receiver measurement engine IC to address challenging safety-critical applications including autonomous driving and advanced driver-assistance systems (ADAS). When used with fully integrated STA5635S RF front-end, TeseoAPP is a complete multi-band ASIL-B GNSS receiver measurement engine solution.

Our Teseo III series of standalone GNSS-L1 receiver ICs (STA8090xx and STA8089xx) offers reduced power consumption, carrier-phase tracking for higher accuracy, and support for Read-only Memory (ROM).

In addition to a full development ecosystem including a complete standalone GNSS module evaluation and prototyping platform, developers will appreciate the user-friendly Teseo-Suite software tool, X-CUBE-GNSS1 expansion software for STM32Cube, and the AndroidHAL-Teseo HAL device driver for Android/Linux systems.

Teseo GNSS solutions come with different package options compatible with the Teseo  Dead-reckoning Automotive Way (Teseo-DRAW) multi-sensor fusion firmware for automotive dead-reckoning and assisted navigation applications and Teseo Dead Reckoning Unplugged Mode (Teseo-DRUM) multi-sensor fusion firmware for dead-reckoning in industrial and IoT applications.

Moreover, members of the ST Partner Program offer a wide range of solutions to provide custom GNSS data correction, assisted GNSS and cloud-offloading services.
