不同大地坐标系的转换。七参数转换模型的基本过程，内涵高斯正反算。

本程序可以自动将标定的框标坐标系到像平面坐标系的转换，实习坐标系转换的自动化。-The program can automatically block the calibration standard coordinate system to the image plane coordinate conversion, coordinate transformation practice automation

将J2000惯性系下的坐标转换到RTN卫星坐标系下。-It is a coordinate conversion program J2000 to RTN.

利用已知点在不同坐标系下的坐标值，根据最小二乘法的原则，求出七参数，实现不同空间直角坐标系的转换。(According to the principle of the least square method, seven parameters are obtained by using the coordinate values of known points in different coordinate systems to realize the transformation of dif
