The Scheduling Model and Solving Algorithm of the Satellite Data Receiving

Satellite data transmission and receiving is one of the two important stages on earth observation satellite executing the tasks of users,and it is an optimization problem with multi-time windows and multi-resources constrains. As the important component of data transmission system,the relay satellite can provide the possibility that the data can transmit all-weather and real-time. The paper mainly expounds these two jobs about the data relay data relay system. Firstly,we set a data transfer containing risk control scheduling model. Secondly,we combine the Tabu Search and Gene Algorithm to solve the model. Furthermore,we adopt distributed parallel computing strategy to improve the convergence rate and robustness of the algorithm. Finally,the distributed simulation system validates the effectiveness of the algorithm and data transfer scheduling model.
