MATLAB/STK Joint Simulation Method and GUI Design

摘要:

详细介绍了MATAB(矩阵实验室)与STK(卫星工具箱)软件互联的方法;STK提供了相应的二次开发接口,可供MATLAB等软件进行二次开发;利用MATLAB和STK软件组合搭建仿真环境,以某Walker星座的设计与优化算法为例,具体介绍了联合仿真步骤流程及GUI界面的设计方法,并综合考虑了卫星轨道、传感器以及卫星编队等相关参数对星座最优设计的影响;结果表明,利用MATLAB和STK组合仿真能够以图像及数据列表的形式方便直观的给出最优结果,通过联合仿真,较大程度上减小了MATLAB的编程工作量,同时通过GUI界面的设计,以可视化的形式对主体程序进行集成,只需输入参数,便可快速进行相应的轨道仿真与数据输出,避免了在进行卫星星座设计时需反复对STK参数进行调整的工作；在对卫星星座设计与运行轨道的问题分析中,MATLAB/STK联合仿真相较于使用单一软件进行问题分析而言,要更加便利、形象直观。

Abstract:

This paper introduces the method of MATLAB (Matrix Laboratory) and STK (Satellite Tool Kit) software interconnection. STK provides MATLAB the corresponding interface for further development. Using MATLAB and STK software to build simulation environment, the algorithm design and optimization of a constellation of Walker as an example, introduces the steps of the joint simulation process and the design method of GUI interface, and considering the influence of the satellite orbit, sensor, satellite formation and other related parameters on the optimal design of constellation. The results show that the combination of MATLAB and STK can be used to obtain the optimal results in the form of image and data list. The workload of MATLAB programming were greatly reduced by joint simulation. The corresponding track simulation and the data output can be completed when it comes to input parameters. It avoids the need to repeatedly adjust the STK parameters in the design of satellite constellation. In the analysis of the design of the satellite constellation, the MATLAB/STK joint simulation is more convenient and intuitive than a single software.
