    STMicroelectronics’ Automotive-Qualified Navigation Module with Dead Reckoning Simplifies Design and Boosts Performance

    To support the positioning market with state-of-the-art GNSS chipset and modules, STMicroelectronics has introduced the Teseo-VIC3DA, the latest member of the Teseo module family.

    Teseo-VIC3DA combines ST’s high-performing Automotive Teseo III GNSS1 IC with the automotive 6-axis MEMS inertial measurement unit (IMU) and dead reckoning software to create a convenient, automotive-qualified navigation module.

    Leveraging ST’s in-house manufacturing and software-development competencies, the Teseo-VIC3DA module enables competitively priced in-car navigation, fleet-management, and insurance-monitoring applications.

    The automotive Teseo III GNSS IC at the heart of the system is proven in high-end systems and is already highly regarded for its accuracy and efficiency. With multi-constellation awareness, Teseo III offers robust positioning capabilities by simultaneously receiving signals from GPS, Galileo, GLONASS, BeiDou, and QZSS constellations.

    The ST 6-axis automotive-grade MEMS IC introduces super-high-resolution motion tracking in advanced vehicle navigation and telematics applications.

    With the combination of ST’s Teseo III, IMU, and dead reckoning, the Teseo-VIC3DA ensures extremely accurate positioning performance in critical environments like tunnels, beneath structures such as bridges or multi-level highways, in covered areas such as underground parking lots, and even in urban canyons between tall buildings.

    The Teseo-VIC3DA module operates from 3.3V, helping to simplify system integration, and has a standby mode that draws just 17µA to minimize demand on the vehicle’s electrical supply. Containing a highly accurate integrated Temperature Compensated Crystal Oscillator (TCXO), the module achieves excellent accuracy of 1.5m CEP2 for typical automotive use cases. In addition, a dedicated real-time clock (RTC) oscillator helps ensure fast time to first fix (TTFF).

    Coming with firmware pre-loaded onto built-in Flash memory, the Teseo-VIC3DA can be updated with new firmware as necessary using the free TESEO-SUITE software. Teseo-VIC3DA can provide up to 30Hz dead-reckoning fix-rate and has very low latency to reduce the UART-channel jitter. Teseo-VIC3DA can autonomously work with and without odometer information.

    The Teseo-VIC3DA is tested and certified by ST according to the EU’s Radio Equipment Directive (RED), applicable ETSI standards, and EN safety standards, helping customers achieve mandatory product-level approvals quickly and efficiently. A standalone, USB-powered evaluation platform, EVB-VIC3DA, is available to jump-start development.
