STMicroelectronics TESEO-VIC3D Dead-Reckoning GNSS GPS Module 24 Channels -156 dBm Sensitivity TESEO-VIC3D

STMicroelectronics TESEO-VIC3D is a high-performance dead-reckoning GNSS GPS module designed for precise, standalone global navigation applications. It integrates a TeseoIII single die standalone positioning receiver IC capable of simultaneous multi-constellation operation across GPS, Galileo, Glonass, BeiDou, and QZSS systems, offering reliable positioning accuracy with a 1.5 meter CEP. The module's acquisition sensitivity of -156 dBm and tracking sensitivity of -163 dBm enable robust signal reception even in challenging environments.

This compact module comes in a 24-pin LCC package measuring 16.0 mm x 12.2 mm x 2.42 mm, optimized for automotive and industrial installations. It requires a stable 3.3 V nominal supply voltage, supporting a minimum of 2.97 V and maximum of 3.63 V, ensuring compatibility with various power systems. The cold start time to first fix of 32 seconds minimizes startup delays, improving operational efficiency.

Operating over a wide temperature range from -40 °C to +85 °C, the TESEO-VIC3D is suitable for harsh automotive-grade environments. The embedded flash memory allows firmware upgrades to maintain functionality and integrate future improvements without hardware changes. The module features an integrated 6-axis inertial sensor enhancing dead-reckoning capabilities, making it ideal for automotive navigation systems where GPS signals may be temporarily unavailable.

Supports 24 multi-constellation GNSS channels ensuring accurate and reliable global positioning. High acquisition sensitivity (-156 dBm) and tracking sensitivity (-163 dBm) make it suitable for signal-challenged locations.

Compact low-profile packaging eases integration into space-constrained applications. Embedded flash enables firmware updates for enhanced performance and features. Robust operation across automotive temperature ranges (-40°C to +85°C).

Low power consumption with standby current of 17 μA supports energy-efficient system design. Provides precise positioning accuracy of approximately 1.5 meters CEP. Combines GNSS positioning with inertial sensor data for dead-reckoning to maintain location during signal loss.

This GPS module is predominantly used in automotive navigation, industrial tracking, fleet management, and other applications requiring reliable satellite navigation combined with inertial measurement. It supports integration into embedded systems and can improve overall system efficiency with quick startup and low power standby modes. STMicroelectronics TESEO-VIC3D addresses critical requirements of modern GNSS solutions for demanding environments.
