对于平台式惯导系统来说，初始对准就是要将平台坐标系向导航坐标系对准。工程文件夹下新建如下6个文件夹，分别用于放置源文件和生成的文件。（其中list和obj文件用于存放相应类型的生成文件，可以使编译完的工程文件夹内文件整洁，不至于有太多文件混在一起）(For the platform inertial navigation system, the initial alignment is to alignment the platform coordinate system to the navigation coordinate system. Under the engineering folder, the following 6 folders are built to place the source files and the generated files, respectively. In which list and obj files are used to store corresponding types of generated files, so that the files in the compiled engineering folder will be clean, without too many files mixed together.)
