CSP Model of the Relay Satellite Scheduling
GU Zhong-shun · Journal of National University of Defense Technology · 2005
The relay satellite, circulating on the GEO (Geogra phic Earth Orbit), can view the user spacecraft on the LEO (Low Earth Orbit) and the MEO (Middle Earth Orbit) directly as well, and view the ground station dire ctly. T he relay satellite can be seen as the bridge between the user spacecrafts and th e ground station. The scheduling problem within TDRSS (Tracking and Data Relay S atellite System) is a very important problem. It analyses the characteristics an d the constraints of the relay satellite scheduling, and then builds the CSP (Cons traints Satisfaction Problem) model of the problem based on CSP theory. The CSP model is solved with STK (Satellite Tool Kits) and simulation method. Computatio nal experiments indicate that the performance of the CSP model is quite good.
