The angle with the plumb line could be determined by the deviation of the vertical with spherical trigonometry.
发射点偏差对弹道导弹射击所引起的偏差可归结为垂线、法线与地心矢径的夹角不同和瞄准方位的不同,利用球面三角知识通过垂线偏差求出垂线与地心矢径的夹角,在诸元计算软件中适当修改一下诸元计算方法,使发射坐标系与标准发射坐标系完全重合,可以完全修正垂线偏差的影响,从而可以大大提高弹道导弹的射击精度。

Based on the theories of spherical trigonometry and theoretical knowledge about projection,this paper introduces two ways(the calculation and diagrammatic representation)of finding the shortest path in a flying range and the conditions to ensure a plane to fly in this path.
根据球面三角理论和投影理论知识 ,用计算和图示两种方法给出了求解航程中最短路径和保证飞机在此路径中航行的条件 。
补充资料:球面三角
研究球面三角形的边、角关系的一门学科。从十六世纪起由于天文学、航海学、测量学等方面的发展,球面三角逐渐形成了独立学科。
