Satellite Orbit Determination and Tracking Model Using Two-Line Elements Set

Satellites play great role in our life; they are used to perform many tasks that couldn't be achieved without them. When the satellite launch to its orbit and in order to achieve its mission, the satellite needs to communicate with the ground station to receive the commands and instructions and also send its information to the ground station, but the ground station can't communicate with the satellite directly before precisely determine its location. Hence, the objective of this research is to design and implement satellite tracking model to determine and track precisely the position of the satellite in its orbit in order to allow the ground station to communicate directly with it using the Two Line Elements Set which are unique for each satellite and need to be accurately specified. This tracking model was designed and developed in three phases: inputs phase, prediction phase and outputs phase. It include graphical user interface that shows illustration of satellite position in its orbit and also shows the value of all necessary data that are required to track the satellite and to predict its motion track.
