| Abstract: | Tracking and locating of Mars probes for hundreds of millions kilometers away is one of the key technologies of the Mars exploration. Now China＇s deep space network hasn＇t been constructed and the location accuracy of MEX by Chinese VLBI Network is only 0. 1 as, which is difficult to provide security for precise orbit determination of Mars probes. A new method of locating mars probes by using remote sensing images is proposed, which adopts strict sensor imaging geometric model through matching of ground control points and the corresponding image points. Result of positioning experiments on Odyssey shows that the new method makes the accuracy up to 2. 93 mas, providing theory and technical support for the location of Mars probes. |
