Resources minimization in the satellite navigation process

There is no doubt that orbit determination (OD) is one of the most important aspects of controlling satellite motion. Minimizing the resources and observation data, which are required to navigate the satellite motion, will make the navigation process more reliable, and robust. In this paper, the methods of orbit determination and estimation will be analyzed from the point of view of the resources and observation tracking available. The paper will make a comparison among possible solutions using combinations of the available tracking data. The different combinations of the tracking data will be analyzed and optimized to define and state the minimum possible data that should be sufficient to handle the problem of orbit determination
