基于STK的微小卫星姿态控制可视化演示与验证

Visualized Demonstration and Confirmation of Microsatellite Attitude Control Based on STK

为了探索微推进器用于微小卫星姿态控制的可行性方案,需要开发微小卫星姿态控制过程的可视化演示与验证平台。以某型号微小卫星为仿真对象,利用Matlab设计了卫星俯仰通道和滚动/偏航通道的姿态控制模型,并实现了卫星姿态控制的数据仿真。基于STK中的STK/Connect模块,实现了卫星姿态控制过程的可视化演示。在可视化过程中,结合某型号微小卫星的案例数据,验证了所设计的卫星姿态控制模型与可视化程序。

In order to offer a visualized demonstration tool to the feasible project of the microsatellite attitude control using micro-thruster,being one kind of microsatellite as simulated object,firstly,the microsatellite attitude control model of pitch channel and roll/yaw channel is designed using matlab software,and the data simulation of satellite attitude control is realized.Secondly,based on the STK/Connect module,the visual demonstration and confirmation of the microsatellite attitude control process is realized.In the visualized process,through proven by some case data of one kind of microsatellite attitude control,the designed models and codes are correct and feasible.
