In order to improve the modeling efficiency,reliability,maintenance ability and expansibility,the object-oriented technology is adopted to design a spacecraft rendezvous GNC simulation system.Based on the UML,GNC system function is conceptually modeled from users' view,and the kernel object,class and the relationship between them are functionally modeled.The key events,flows and the activities are modeled by sequence,state and collaboration chart either.The simulation system is preliminarily implemented and it can meet the simulation requirements of various backgrounds and granularities.The results validate the characteristic of the modeling,and illuminate that the design method is feasible.
