Abstract: For the poor extensible characteristics of existing satellites scheduling systems, a high-extensible satellite scheduling system named HES3 (High-Extensible Satellite Scheduling System) was designed and implemented based on the framework similar to High Level Architecture (HI_A). A two-stage scheduling process which is composed of expert system and scheduling algorithm with constraints independence was proposed to promise the high-extensible character of HES3. Then a Graphical Uscr Interface (GUI) was designed to illustrate the scheduling result in the form of a view similar to Gantt and a view based on Geographic Information System (GIS). Finally,a demonstration was conducted to show how HES3 works.

Key words: Satellites scheduling, Scheduling system, High-extensible
