火箭弹制导化中的坐标转换问题

摘要

Space-earth coordinate is commonly used in navigation and positioning, but in navigation system of missile emission coordinate is usually used. After the correlative coordinate of earth is detailed, in virtue of the earth-rectangular coordinate, the position, velocity and attitude angle of the missile can be converted from space-earth coordinate to emission coordinate.%地球导航定位通常采用空间大地坐标系,导弹发射通常采用发射坐标系.详细定义相关地球坐标系后,可借助大地直角坐标系,将弹体位置、速度、航姿角从空间大地坐标系转换到发射坐标系.
