Design of trajectory generator of triaxial swing based on inertial sensors

Based on the analysis of the sea environment, the trajectory generator of triaxial swing based on inertial sensors under different sea conditions is designed using the inertial navigation system (INS) algorithm and the law of carrier´s motions. The trajectory generator can act as a virtual instrument of navigation, guidance and control systems which can produce trajectory information (attitude, velocity and position) of the carrier under the given movements and the original measurement information of inertial components (gyroscope and accelerator). When the practical experiment is difficult to be conducted, the trajectory generator can create navigation data for the simulation and verification of the methods of navigation, guidance and control. Moreover, the errors of navigation, guidance and control systems influenced by different measurement errors of the inertial sensors (gyroscope and accelerator) can be studied.
