As an interfaces instance of observation plan service between the virtual constellation and the small satellite systems, this paper proposes a practical method applied in rapid interface modeling in the design phase. An UML sequence diagram is used to describe the application scenes, the request and response parameters, the communication performance, the parameters source of each service-side interface and the timing constraint between interfaces. On this basis, this paper defines the XML schema for every interface parameters. An UML static structure is used to analyze interface type to form interface methods tree. In conclusion, this study promotes the change of service mode from single satellite programming to multi-satellites collaborative observation.
