【摘 要】:為了提高大地緯度的解算精度,以Bowring 1976公式為基礎(chǔ),通過減小歸化緯度的偏差,給出兩種大地經(jīng)緯度解法,使得解算精度從[10-3]″量級分別提高到不低于[10-10]″、[10-14]″量級。

【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
將空間直角坐標(biāo)轉(zhuǎn)換為大地經(jīng)緯度坐標(biāo),是大地測量、彈道計算、航空航天、衛(wèi)星測控等工作的基本問題;但由空間直角坐標(biāo)計算大地緯度,沒有直接解算公式。(剩余2794字)
