Research of Time Zero Method in SINS/GPS Data FusionWANG Zhong-tao, WANG Ji-bing China Airborne Missile Academy, Luoyang 471009, ChinaAbstract:
In practice, the data fusion must be on the same time point, but the datum come from SINS and GPS are not on the same time point, and so it is essential to calibrate these datum to the same time point before data synchronization fusion. By comparing the different methods of data fusion, subsection linear imterpolation method is used to calibrate the datum of SINS and GPS. The simulation results show that this method meets the requirement for the system.[著者文摘]
