STMicroelectronics Teseo-VIC3DA Automotive GNSS Dead-reckoning Module

With embedded 6-axis IMU inertial sensor, Superior Accuracy, Automotive AEC-Q100 Qualified

Teseo-VIC3DA module is an easy to use dead-reckoning Global Navigation Satellite System (GNSS) standalone module, embedding TeseoIII single die standalone positioning receiver IC working simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS).

The Teseo-VIC3DA module brings the proven accuracy and robustness of TeseoIII chip to the reach of everyone: the embedded firmware and the complete evaluation environment save development time.

Within its 16.0 mm x 12.2 mm size, Teseo-VIC3DA is offering superior accuracy thanks to the on board Temperature Compensated Crystal Oscillator (TCXO) and a reduced Time To First Fix (TTFF) relying to its dedicated Real Time Clock (RTC) oscillator. Thanks to the embedded flash Teseo-VIC3DA offers many extra features such, 7 days Autonomous Assisted GNSS, Predictive Assisted GNSS and Real-Time Assisted GNSS.

Teseo-VIC3DA supports FW configurability as well as FW upgrades. Teseo-VIC3DA module, being a certified solution, optimizes the time to market of the final applications with a temperature operating range from -40 °C to +85 °C.
