摘要
With the research on space-based detecting space debris, this paper presented the space debris orbital detecting method with satellite-based CCD(Charge Coupled Device) camera. Firstly, CCD photogrammetric observation model and orbit determination of the space debris were set up. The theory of plane adjustment for the CCD camera was analyzed, which shows that the observation data derived from the CCD camera are independent from the attitude of the tracking satellite. The precision of observation data from the CCD camera are just dependent on observation and reference frame transformations, which can be gotten accurately. Then, the paper researched orbit determination of space debris on the LEO (Low Earth Orbit) and GEO (Geostationary Earth Orbit), where the density of the space debris is very high. The results indicated that orbit determination precision with the camera data of two tracking arcs is higher than with one tracking arc; The less distance between the tracking satellite and the space debris, the more accurate for orbit determination; Orbit determination precision of the space debris in LEO is lower than that in GEO.
