This product is built with high-precision three-axis single-fiber
gyroscopes, high-precision quartz flexible accelerometers, and a
mobile mapping-grade multi-mode and multi-frequency GNSS receiver
supporting independent Beidou functions. Through advanced
intelligent integrated navigation algorithms and Kalman filtering,
and optimized design for GNSS occlusion and multipath interference,
it can achieve high-precision measurement of heading, attitude,
speed, and position of moving carriers.
This inertial navigation system has a variety of sensor interfaces
such as GNSS/odometer/DVL/barometric altimeter, which can well meet
the needs of long-time, high-precision and high-reliability
navigation applications in complex environments such as urban
canyons, and can be used for the navigation and control of various
unmanned systems.
