摘要
如何快速、准确地完成惯导系统的初始对准一直是惯导系统研究的关键技术，方位对准精度和对准时间的矛盾至今未能很好地得到解决。为解决这一问题，本文提出了双全球定位系统（ＧＰＳ）同惯性导航系统（ＩＮＳ）进行深组合的方法。仿真结果表明，该方法使方位对准时间缩短为不到２ｍｉｎ，精度达到１４．６７（″），较好地解决了方位对准问题，同时也提高了导航精度。
It is a key technology all along to realize the initialization of inertial system quickly and preciously. The contradictory of precision and time of head initialization have not been fairly good resolved so far. In order to resolve this problem, the method of the deep integration of double GPS with inertial system is presented. The simulation results show that this method shortens the time of head initialization to less than two minutes and resolve fairly good the problem of head initialization,while the precision of navigation has been also improved.
