precise ephemeris

基本解釋

The broadcast ephemeris, which is the basic of satellite navigation, must be precise and real time.
衛(wèi)星導(dǎo)航定位的基礎(chǔ)，要求有較高的精度和實時性。
The thesis uses the generalized extended interpolation method in precise satellite ephemeris and clock bias interpolation and GPS height fits.
本文采用廣義延拓法進行衛(wèi)星精密星歷插值、衛(wèi)星精密鐘差插值和GPS高程轉(zhuǎn)換。
On the basis of the periodicity of the designed orbit of GPS satellite, trigonometric function polynomial interpolation method is used to interpolate the IGS precise ephemeris.
考慮到GPS衛(wèi)星的設(shè)計軌道具有明顯的周期性，用三角函數(shù)多項式方法進行精密星歷插值，并與經(jīng)典的拉格朗日插值方法進行了比較。

精密星歷
Since the availability of GLONASS precise ephemeris and clock products, the combined GPS/GLONASS precise point positioning has become possible. In this thesis, the main research contents are as follows.
隨著GLONASS精密星歷和衛(wèi)星鐘差數(shù)據(jù)產(chǎn)品的出現(xiàn),組合GPS/GLONASS精密單點定位已成為可能。
