摘要：

COMPASS-GEO is equipped with orbit measurement of the C band transponder and the L band pseudo-range. These two types of observation data of COMPASS-GEO navigation satellite is pre-processed and the orbit determination is tested in the paper. The result shows that without synchronous time information the orbit determination accuracy is poor by using the L band pseudo-range data singly. But high orbit accuracy is abstained with the C band transponder data if the observation stations system bias is accuracy and the satellite transport time-delay is stable. However, the clock error with satellite and station, the satellite trajectory and the satellite transport time can be detemined with the union of two types of observation data. The accuracy of one day's orbit detemination is 6.67m compared with the long arc transponder data determination results.
