1、Matlab与STK连接函数库最新整理Matlab与STK连接函数库(最新整理)Matlab与STK连接函数库整理者：龚德仁2008年10月7日一、Matlab/Simulink、STK联合仿真的优势STK/MATLAB,SIMULINK STK与Matlab联合实现可视化仿真集成，该方案可以适用于航空航天、航海、作战模拟、电子对抗、卫星导航定位、遥感遥测、卫星通信等各个可视化仿真集成案例之中。STK/MATLAB接口为STK和MATLAB提供了双向通讯功能，在MATLAB工作区通过Connect模块以TCP/IP协议打开STK端口。 利用超过150个MATLAB命令增强STK的轨道、弹道、轨

2、迹的分析能力，MexConnect还提供在MATLAB命令行直接使用任意 STK/Connect 命令的功能。MexConnect工具可以建立各种不同级别的STK对象，进行操作并生成报告。所有STK的数据，包括动态位置、速度和姿态数据，可以返 回到MATLAB工作空间，用于数学分析。宇航工具箱让MATLAB用户可以输出多重坐标系，以及符合STK格式的星历和姿态文件用于VO模块的三维可视 化。另外此工具还可以使用STK附加模块的功能如STK/COMM（通信），STK/Coverage （覆盖）和STK/Radar（雷达）。表1 STK模块基本模块基本版专业版三维显示高级三维显示Satellite
