Application of Relay Satellite Scheduling based on STK/X

Tracking and Data Relay Satellite (TDRS) has been seen as bridge not only between user spacecrafts in LEO (Low Earth Orbit) or MEO (Middle Earth Orbit), but also between user spacecraft and groundstation. The paper firstly introduces the main function of STK and its components. Then based on the characteristics of Relay Satellite Scheduling, a scheduling system is designed with vc++/STK/X and validated by a set of typical operation datas. The result shows that the model can resolve small-scale relay satellite scheduling problems and reduce exploitative difficulty of application.
