Abstract
In order to calibrate the error coefficients of the gimbaled platform inertial navigation system on precision centrifuge precisely and effectively, a six-position calibration scheme is provided. Firstly, the error models of the platform inertial navigation system are established and the applied acceleration equation is given. Then, the redundancy of the error coefficients is analyzed and a method of studying the observability based on the correlation coefficients is proposed. Finally, the optimal calibration scheme is obtained using the genetic algorithm. Simulation results show that the error coefficients can be effectively calibrated through the proposed scheme.
