Research on the conversion technology of landing points motion attitude based on limited sensor parameters
For large surface ships using the deck as a helicopter takeoff and landing platform,the installation position of the shipborne inertial navigation device is far from landing points,and the lever arm effect has a significant impact on the parameters identification of the extremely short-term prediction model for ship motion,seriously affecting the accuracy of heave motion prediction.This article uses real-time roll,pitch and heave information collected by limited attitude sensors,combined with relevant ship coordinates,to derive the heave speed of landing points from theoretical analysis,and uses ship model test data to verify the heave conversion error and the accuracy of heave short-term prediction.The test results indicate that the conversion of landing points heave motion is of great significance for improving the accuracy of heave short-term prediction and assisting in guiding helicopters landing.
