Introduction
HWA-RLG5100 ( Ring Laser Gyro) strap-down inertial positioning and orientation system adopts laser gyro and quartz flexible accelerometer, which is a strap-down system scheme. It can realize independent positioning and orientation by combining with odometer and altimeter, and can form an integrated navigation system with Beidou / GPS composite receiver, which can meet the requirements of vehicle carrier for north finding, azimuth maintenance, horizontal attitude determination and elevation.
In the initial alignment and north seeking stage, the Kalman filter technology is used to realize the initial alignment and the error compensation of inertial elements by using the position, elevation and zero speed information; in the moving process, the Kalman filter is used to estimate and compensate the system error in real time by using the output information of odometer and altimeter, so as to provide higher horizontal positioning accuracy and azimuth maintenance Accuracy. According to the system configuration and needs, it can also form an integrated navigation system with Beidou/GPS composite receiver.
