The prediction and positioning of impact sites are based on the extrapolated orbiting data together with the real time orbiting data and observations from ground based telescope provided by TT ＆ C System. As most lunar missions carded cameras onboard, a new method of positioning of CE-1 impact site is put forward. It is based on the CCD image data photographed during the con- trolled impact and the existing lunar terrain data. Test results from this new method also validate the published impact site po sition.展开更多
