High-Precision GNSS RTK Dead Reckoning Solution for Smart Driving & Lane Level Navigation

LOCOSYS RTK-4671-MHDR is a high-precision RTK solution targeting for the smart driving and lane-level navigation markets. The latest designed LOCO II engine architecture is optimized to offer a seamless experience in dense urban canyons. RTK-4671-MHDR takes the shortest time to fix position and
continues to work where GNSS signals are poor or not available.


Centimeter-Level Positioning & Dead Reckoning / Support Rover

RTK-4671-MHDR is a cost-effective RTK receiver for cm-level positioning and accurate raw measurements output, which can be integrated into autopilots and inertial navigation units.

RTK-4671-MHDR supports multiple constellations, including GPS, GLONASS, BeiDou, GALILEO, QZSS and SBAS to improve the continuity and reliability of RTK solution even in harsh environment. It features powerful compatibility with other GNSS boards in the market by flexible interfaces, smart hardware design and popular log/command formats.

RTK-4671-MHDR not only supports multi-constellation RTK, but also has inertial sensors (3-axis accelerometers and 3-axis gyros). It can provide dead reckoning with or without odometer connection. The centimeter-accurate position, dead reckoning and low power consumption meet the requirement of lane-level car navigation and other location-based applications.
