球面上两点之间的最短连线的长度,就是经过这两点的大圆在这两点间的一段劣弧的长度。(大圆就是经过球心的平面截球面所得的圆)
并且通过对模型的分析,采用MATLAB编程计算球面距离。
By analyzing the model, we calculate the spherical distance in MATLAB programming method.
用解球面三角形的方法,通过两天体的球面距离,求得星位角,从而求得船位的经纬度。
Through the solution, the star position angle can be found with so - called "star distance" (Short for the spherical distance between two stars)determined So as to have the fix solved.
在其他情况下使用球面模型,所使用的主要距离计算为大圆弧长(参见参考资料)。
In other cases, a spherical model is used, and the primary distance calculation used is the great-circle distance (see Resources).
