How Can Your Navigation System Maintain Accuracy in Tunnels and Underground Parking?

The ST-1612r-DBX automatically switches between ADR and UDR modes using built-in 3-axis accelerometers and gyroscopes, delivering continuous positioning when GNSS signals are blocked. With multi-constellation support and MEMS raw data output up to 100Hz, your navigation systems achieve seamless operation in challenging environments. Contact us to integrate this AEC-Q100 qualified module into your next-generation automotive navigation platform.

Engineered for automotive OEM and aftermarket applications, the ST-1612r-DBX outputs both raw inertial sensor data (up to 100Hz) and vehicle altitude parameters including pitch, roll, and heading angles, enabling advanced driver behavior analysis and emergency call (E-Call) functionality for connected vehicles. The module's automatic calibration function and no installation orientation requirement simplify integration, while multiple interface options (UART, CAN Bus ISO 15765-4, USB) and support for various vehicle speed input methods ensure compatibility with diverse automotive systems. Manufactured under LOCOSYS IATF 16949 quality control standards, this compact 16 x 12.2 x 2.3 mm SMD module operates reliably across -40°C to 85°C, making it ideal for automotive navigation, M2M applications, and track patrol vehicles requiring robust, continuous positioning performance.

ST-1612r-DBX

The LOCOSYS ST-1612r-DBX Dead Reckoning (DR) module is the perfect solution for automotive application.
The LOCOSYS ST-1612r-DBX Dead Reckoning (DR) module is the perfect solution for automotive application.

LOCOSYS ST-1612r-DBx dead reckoning (DR) modules are the perfect solution for automotive application. They not only support GPS, BEIDOU, 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-DBx 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.
