| Abstract: | This paper studys the scheduling problem of muti-satellite, muti-data reception station with muti-rate, considering the time constraints, mission privilege and the maximum uses of the resources.We give a programming model and a corresponding algorithm to solve this problem. At last, we validate the model and algorithm through the scheduling problem of two satellite case. |
