A new initial alignment method of MIMU based on CCD

A new initial alignment of MIMU based on CCD is proposed in this article to overcome problems of time consuming and low accuracy of the traditional HMS. By utilize the attitude information provided by CCD, MIMU can achieve initial alignment process and output real-time head attitude to compute line of sight. Simulation results indicated that the CCD measurement system can effectively reduce the wasting time of initial alignment and improve attitude measurement precision.
