Abstract�� Satellite data transmission scheduling problem based on multi-satellite combined reconnaissance is such a problem that studies how to assign ground resources and data transmitting time for every single data transmission task belonged to satellite data transmission task.A study of the problem-s model was made. To this problem, the models of single data transmission task and satellite data transmission task were constructed firstly. Based on these models, the model of this problem was constructed, and the object function and main constraints were analyzed especially. For solving the problem, a heuristic scheduling algorithm named double complex priority algorithm (DCPA) was presented and validated by an example lastly. The studying results realize formalizing description of the problem, and give a valid solving algorithm for it.
