| Abstract: | The analysis methods of the influence of the gravity anomaly field on long-range rocket are firstly introduced as well as their influence mechanism. Then, the progress on methods for rapid reconstruction of the gravity anomaly field is also reviewed. Finally, three kinds of compensation methods for the influence of gravity anomaly field, namely the trajectory data compensation method, guidance data compensation method and onboard real-time compensation method, are compared and evaluated. The work in this paper provides support for improving the accuracy and rapid response capability of long-range rocket under gravity anomaly field. |
