查询词典 ephemeris time

Based on satellite ephemeris and time data of the satellite coordinates of the celestial coordinate system.

详细说明：根据卫星星历和时间数据计算卫星在天球坐标系中的坐标。

To achieve precise ephemeris data to the reader, and interpolation from any point in time the satellite location and can assess the accuracy...

实现对精密星历数据的读取，并能内插出任意时间点卫星的位置，且能评定内插的精度。

By using high-resolution reference data to identify accurate GCPs, considering the spacecraft attitude deviations which TBUS can't supply, and adjusting the epoch time and ephemeris data at the criteria of constraint LeastMean-Square-Error, the geolocation accuracy of navigation for AVHRR data can be improved greatly.

由于采用具有足够定位精度的高分辨率参考图象以提取高精度的地面控制点，考虑了TBUS轨道报所不能提供的卫星姿态偏差，对历元时刻和卫星轨道根数进行有约束条件的参数最优调整，可使整条轨道大范围内的AVHRR导航定位精度有较大提高。

With adjusting the epoch time and ephemeris data at the criteria of constraint Least-Mean-Square-Error, the geolocation accuracy can reach 2 pixels in the whole images; and it can be improved to approximately 1 pixel in the whole images and less than 1 pixel at nadir by considering the spacecraft attitude deviations moreover.

如果进行历元时刻和卫星轨道根数的约束最优调整，导航定位精度在整条轨道大范围内可提高到2个像元左右；如果再加入卫星姿态偏差的校正，导航定位精度在整条轨道大范围内可稳定提高到1个像元左右，在星下点附近小于1个像元。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
