Dynamic leveling method under independent work mode for airborne remote sensing stabilized platform

According to the installation characteristics of gyroscope and accelerometer on the frame for airborne remote sensing stabilized platform, a dynamic angle measurement scheme is presented, in which the accelerometer is the main component, and gyroscope is the support. A correction method for handover frequency of complementary filter is raised according to statistical characteristics of the measurement noise, and a Kalman filter is designed based on complementary filter. To validate the performance, the complementary Kalman filter was experimented for airborne remote sensing stabilized platform principle proto made by our research group. The results show that the leveling accuracy of the platform has been greatly improved in both static and dynamic condition, laying the foundation of improving the working time and leveling precision of the stabilized platform under independent work mode.
