Abstract:
In this paper, the accuracy of the satellite on board orbit calculation is compared with a ground based system calculation. The objective is to determine whether the on board satellite orbit propagator software is sufficient enough for Optical Intersatellite Link communication between a Low Earth Orbit and Geosynchronous Earth Orbit satellites and figuring out the possible reasons of any inaccuracy if any. The study is done by using TURKSAT 3A Geostationary satellites’ data. Even the software on board the TURKSAT 3A does not intend to provide fine orbital position for intersatellite communication, this study is done in order to conclude the convergences and open points on the onboard orbit propagator. First, a quick summary is given for TURKSAT 3A satellite and its’ station keeping philosophy. In the following sections, comparisons are done between on board and on ground orbit calculations with different time intervals of the year 2010. The possible root causes of the differences between these two calculations are discussed at the end.
