Özet:

Abstract: Many different observational systems have been used to determine orbits of artificial satellites and space debris The leading systems on this topic can be summarized as;optics, RADAR and LIDAR. This study aims to establish the orbit determination of artificial satellites and space debris in the Low Earth Orbit (LEO) based on observational methods with no dependence on any geographical coordinate by using COTS (Commercial off-the-Shelf) products, instead of employing expensive and complex systems. The observational system established in this study allows the observer to record dimmed objects up to 4.5 magnitude by using the Surveillance Method. Subsequently, by the use of Gauss and Gibbs Methods (Curtis 2005), which enables the utilization of the data in three different coordinates, the position and the velocity vectors of the objects and also the Keplerian Elements in connection with them are able to be calculated. The observational system has an accuracy of 0.1° in position, of 0.5 to 1.0 seconds in timing, and of 4.5 magnitude in brightness.
