Accuracy Analysis of Orbit Determination of Space Objects for Wide Field-of-View Photoelectric Telescope
Based on electro-optical sensor array, the accuracy of space objects precise orbit determination (POD) and orbit prediction (OP) are studied in this paper for the wide field-of-view photoelectric telescopes. The reference orbit of Jason-3 and Cryosat-2 obtained by using satellite laser ranging data from the International Laser Ranging Service, which are used to analyze the POD and OP accuracy of the wide field-of-view photoelectric telescope observations. The calculation results show that the POD root mean square (RMS) position error of the wide field-of-view photoelectric telescope observation data is better than 250 m and the RMS of the velocity error is less than 0.25 m/s. The accuracy of the 3-day orbit prediction based on the POD results is better than 20". The results indicate that the wide field-of-view photoelectric telescope can not only improve observation efficiency, but also obtain accurate orbit information of space objects through post-processing of its observations, which can provide data support for related work and space missions with orbit information.
