Themodule of STK /Scheduler is a scheduling module of STK and offers the function of re- exploitation. This paper studies the application of STK /Scheduler in satellite data transm ission scheduling. At first, based on the analysis of this problem, satellite data transm ission task model and schedulingmodel are established. Then, satellite data transm ission scheduling system based on STK /Scheduler is designed. At last, by using AFIT benchmark, the scheduling result shows thatwhen the task scale isnot very larger, STK /Scheduler is a shortcut for the problem of sat- ellite data transmission scheduling.
