Teseo-VIC3DA and Teseo-VIC3D modules are 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-VIC3Dx 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-VIC3Dx is offering superior accuracy thanks to the on board Temperature Compensated Crystal Oscillator (TCXO) and a reduced Time To First Fix (TTFF) relying on its dedicated Real Time Clock (RTC) oscillator. Thanks to the embedded flash Teseo-VIC3Dx offers many extra features such as 7 days Autonomous Assisted GNSS, Predictive Assisted GNSS and Real-Time Assisted GNSS. Teseo-VIC3Dx supports FW configurability as well as FW upgrades. Teseo-VIC3Dx 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. Teseo-VIC3DA is AEC-Q100 qualified for automotive application.
