摘  要:
播区经纬度的计算,可用播区的边长、设计宽、短距与真方位角的三角函数关系,从南端的一角起,顺序推算,最后推回起点,使经度、纬度的闭合差均等于零。

摘  要:
The calculation of longitude & latitude in disseminated area can, by means of length of edge, width of design, functional relation of triangle between short distance and real position angle, start from southern end reckoning in order and push back to the starting point, which makes misclosure of longitude & latitude all equal to zero.
