Solution Description

Navigation systems, tolling, fleet management, insurance black box, and emergency call applications can benefit from improved location accuracy offered by dead reckoning systems to compensate for inadequate or absent GNSS data.

This dead reckoning solution is based on the standalone Teseo-VIC3D GNSS offering 1.5 m CEP positioning accuracy. The module houses a Teseo III chip with multi-constellation awareness and an embedded 6-axis inertial measurement unit (IMU) to supply accelerometer and gyroscope data when satellite connection is compromised or interrupted. The module is complete with an RF signal conditioning block for incoming satellite data, power management circuitry, flash memory, and two clocks to ensure fast GPS connection and high accuracy. 

The dead reckoning firmware installed on the module outputs position, velocity, and time (PVT) data from GNSS data fusion with readings from the embedded IMU and optional odometer and temperature inputs.

The STM32 microcontroller receives the PVT data for custom applications and interacts with the Teseo-VIC3D using NMEA instructions via UART or I2C ports.
