Promotion Product-MC-1612-DG

LOCOSYS MC-1612-DG is a single-band multi-system with an ARM base processor. It not only supports GPS, GLONASS, GALILEO, QZSS and SBAS, but also has a flash memory, TCXO, RTC crystal, LNA and SAW filter, and embedded MEMS sensors (6-axis accelerometers gyros), 1-hole pressure (option) Micro-Electro-Mechanical Systems (MEMS) sensor, equipped with DR software. The extended Kalman filter algorithm combines GNSS and MEMS sensor data with a weighting function that relies on GNSS signal quality. With adverse GNSS conditions in urban canyons, tunnels, or parking garages where DR boosts the accuracy, and the software fills the gaps. It supports three dimensional DR, Standard NMEA output, fully supports various map mapping demand.

DR Module


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

LOCOSYS 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.
