【Abstract】:In order to improve the accuracy of geodetic latitude calculation, based on the Bowring 1976 formula and by reducing the deviation of normalized latitude, this paper proposes two methods for geodetic latitude calculation, which increase the accuracy of geodetic latitude calculation from the order of 10-3"to no less than 10-10" and 10-14", respectively.
【Key words】:geodetic latitude; iterative solution; direct solution; Bowring formula; calculation accuracy
将空间直角坐标转换为大地经纬度坐标,是大地测量、弹道计算、航空航天、卫星测控等工作的基本问题;但由空间直角坐标计算大地纬度,没有直接解算公式。(剩余2794字)
