The Generic Resource, Event & Activity Scheduler (GREAS(R)) is a resource allocation modeling tool that extends the aerospace analysis capabilities of Analytical Graphics' Satellite Tool Kit (STK(R)). Given a set of tasks that you define, which can differ in duration and importance, and a limited set of resources, which can contain satellites and ground stations defined in STK, GREAS can generate a conflict-free schedule of the tasks which optimally utilizes your limited resources.
