To support the positioning market with state-of-the-art GNSS chipset and modules,STMicroelectronicshas introduced the Teseo-VIC3DA, the latest member of the Teseo module family.
Teseo-VIC3DAcombines ST’s high-performing Automotive Teseo III GNSS IC with the automotive, six-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 six-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.
TheTeseo-VIC3DAmodule 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 CEP for typical automotive use cases.
In addition, a dedicated real-time clock (RTC) oscillator helps ensure fast time to first fix.
Coming with firmware pre-loaded onto built-in Flash memory, the Teseo-VIC3DA can be updated with new firmware as necessary using the freeTESEO-SUITEsoftware. 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.
圣acc Teseo-VIC3DA是测试和认证ording 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.
