high performance INS based on MEMS inertial navigation RTK INS for
unmanned driving
INS570D is a high performance integrated navigation product based
on MEMS inertial navigation technology, which integrates satellite
navigation information (supporting RTK) and vehicle information
(wheel speed, gear, etc.), and adopts vehicle design. It has the
ability to accurately provide attitude, heading, position, speed,
sensor data and other information to vehicles through data bus in
various scenarios (highway, bunker, viaduct, tunnel, city street,
port, etc.). The product adopts good man-machine design, which can
indicate power supply status, satellite information access status,
vehicle information access status, equipment status and other
information to the user through the indicator light. The hardware
(connector) interface adopts error-proof design, which is
convenient for user production, scientific research and debugging.
