ST-1612r-DGx dead reckoning (DR) modules are the perfect solution for automotive application. They not only support GPS, GLONASS, GALILEO and QZSS, but also have inertial sensors (3-axis accelerometers and 3-axis gyros) to provide dead reckoning. They will detect if there is an odometer connection or vehicle speed input, and then automatically operate in ADR or UDR mode.

Both raw data of the inertial sensors and vehicle’s altitude including pitch, roll and heading angles are outputted for the driver behavior analysis. For example, the internet connected vehicles can automatically send emergency calls (i.e. E-Call) for help based on the vehicle’s altitude. No requirement of installation orientation and automatic calibration function make them easy to use. With these features, ST-1612r-DGx can reduce position errors in multipath environment and continue to work where GNSS signals are poor or not available, such as tunnels and indoor parking lots, as well as deliver seamless car navigation.
