摘要：
The alignment of missile-borne Platform initial navigation, requires higher alignment accuracy and shorter alignment time. The accuracy of traditional alignment technique is low and the alignment time of it is long, because the influence of the east gyro drift and the slow speed of the azimuth misalignment angle's convergence. In order to meet the missile-borne inertial navigation requirements of alignment accuracy and rapidity, this paper proposes the alignment technique of missile-borne platform inertial navigation under arbitrary azimuth misalignment angle. Using platform translocation and three times traditional level alignment to find the north (complete azimuth alignment), this technique eliminates the influence of east gyro drift which leads to a serious decline in the accuracy of the alignment, and shorten the alignment time. The simulation results show that the technique can guarantee the accuracy and the speed of the alignment system. © 2013 Binary Information Press.
