The principle of single-station orbit determination using astrometric positioning and SLR techniques is to add a laser ranging unit onto the optoelectronic telescope system, so as to conduct laser ranging and astrometric positioning angle measurement at the same time. By melting and processing all the data together, the new technique will achieve single-station orbit determination of the objects. In this paper, the actual measurement data of satellite Ajisai is analyzed for its single-station single-lap and multi-lap orbit determination. However, due to the limited amount of actual measurement data, objects of three types of orbit altitude have to be simulated and the single-station orbit determination analysis is just based on them in order to make the conclusion more universal. After studying the actual and simulated data, it turns out that for single-station single-lap orbit determination, the ranging measurement data (measurement duration longer than 4 min) will improve the orbit determination accuracy from several kilometers to tens of meters and the 24-h prediction accuracy from thousands of kilometers to several kilometers.
