Abstract:

The performance of high precision inertial navigation system (INS) depends on not only the quality of inertial sensors, but also the accuracy of the gravity information. The accuracy of inertial navigation system can be improved by deflection of vertical (DOV) compensation which is suitable for ready-made systems and almost free of cost. In this paper, the impact of initial alignment on compensation for deflection of vertical is investigated, the completed compensation method is proposed and confirmed by shipborne inertial navigation experiment, and the precision of INS is maximally increased by about 12% after the proposed deflection of vertical compensation.
