How Can You Maintain Accurate Vehicle Tracking When GPS Signals Are Lost in Tunnels or Underground Facilities?

The MG-1612AD-DR's untethered dead reckoning delivers position accuracy within 3% of distance travelled without GNSS signals, using integrated 6-axis MEMS sensors. Your fleet tracking system maintains continuous location data through tunnels, underground parking, and urban canyons—eliminating blind spots and ensuring complete route visibility. Contact us to integrate seamless navigation into your fleet management platform.

Designed specifically for automotive navigation, location-based services, vehicle remote monitoring, and intelligent traffic systems, the MG-1612AD-DR features vehicle dynamics monitoring system (VMDS) capabilities that detect abnormal driving behaviors and vehicle status changes. The module requires no specific installation orientation and includes automatic calibration functions for simplified integration. With multiple interface options (UART/CAN BUS/USB), operating temperature range of -40°C to 85°C, and comprehensive certifications including CE approval, EU Radio Equipment Directive 2014/53/EU, RoHS compliance, and ISO/IATF 16949 manufacturing standards, this dead reckoning module delivers reliable, seamless navigation performance for mission-critical automotive applications worldwide.

MG-1612AD-DR

LOCOSYS MG-1612AD-DR is using an Airoha AG3335AD chip, dual-frequency multi-constellation solution GNSS with sensor fusion dead reckoning module.
LOCOSYS MG-1612AD-DR is using an Airoha AG3335AD chip, dual-frequency multi-constellation solution GNSS with sensor fusion dead reckoning module.

LOCOSYS MG-1612AD-DR is using an Airoha AG3335AD chip, dual-frequency multi-constellation solution GNSS with sensor fusion dead reckoning module. It not only supports GPS, GLONASS, GALILEO, BEIDOU and QZSS, but also has inertial sensors (3 axis accelerometers and 3-axis gyros) to provide untethered dead reckoning function.

In addition to DR, an inertial sensor can detect the vehicular dynamics when it is attached firmly on the vehicle. Consequently, abnormal driving behaviors and the vehicle status can be detected and the alarm status will be enabled to remind the users. No requirement of installation orientation and automatic calibration function make it easy to use. With these features, MG-1612AD-DR 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 navigation.
