| Abstract: |
| In order to improve hit accuracy, inertial/celestial integrated guidance system of single star is researched. Through the establishment of the connection between the star sensor observables, platform disorders angle and impact point deviation, the celestial navigation correction model is built. Through numerical method on the orientation of the optimal single star is determined. Mathematical simulating results show that celestial navigation of single star can reduce guidance instrument error. It is an effective means to improve the hit accuracy. |
