Space and Ground TT&C Resource Integrated Scheduling Model

The integrated scheduling of TTC resources is an optimization problem with complex constraints such as multi-time windows and long-time windows.The requirements for orbit determination and orbit keeping of middle and high orbit satellites are analyzed,then according to the task requirement description of low orbit satellites,a normalized requirement description for all types of satellites suitable for scheduling algorithm design is proposed.Following the performance constraints of TTC resources from space and ground,an integrated scheduling model is established,with maximizing the weight satisfaction rate as an objective,and then a genetic algorithm-based scheduling strategy is formulated.Simulation results demonstrate that the presented model and algorithm are feasible.
