We are now studying high accuracy reentry guidance algorithms for reentry capsule. In this paper, we propose a real-time prediction guidance using numerical integration. The real-time prediction guidance is an explicit guidance law using numerical integration for range prediction during reentry flight. One of technical issues of the real-time prediction guidance using numerical integration is that navigation error and wind error lessens the navigation accuracy. Especially, errors in the last phase of reentry flight affects the navigation accuracy. So we researched that mechanism by investigating the navigation ability (ability of range adjustment) of several navigation segments.
