查询词典 satellite

Currently we have no accurate ephemeris for Charon and no ephemeris for Neptunian satellites at all. The other satellite ephemeris should be correct.

基於目前我们尚未拥有Charon精确的星历表以及海王星的所有卫星也没有任何的相关资料，所以在显示的时候将会有这样的情形发生。

That means satellite data can be used to predict epidemics without having to collect any flies on the ground.

这就意味着，可以用卫星数据来预测流行病，因而不需要在地面上采集任何的苍蝇。

The application of DVB system which started with satellite living broadcast system was adoptted by CATV gradually. By the growing up of Internet, DVB system based on llnternet became the research object of researchers and engineers. However, narrow band and high error rate of Internet limited the application of DVB system which should transport lots of data on network.

DVB体系的应用起始于直播卫星系统，后来逐渐被有线电视系统采用，由于Internet的崛起，有人开始了基于Internet的DVB系统的研究，可是Internet带宽低，错误率高，这些Internet网络固有的局限性，限制了需要大量数据的传播的DVB系统的广泛应用。

The mathematical models of the delay of the GPS signal in the circumstance are put forward respectively. The computation of orbital arc of the two satellite constellations is based on two body problem and perturbations models. An algorithm based on the IRI model and thin layer model is used to simulate the ionospheric delay of the GPS signal. The error models of observation, multipath, relativity and antenna phase center bias are also researched. Under the consideration of the autocorrelation of the electronical measurements, the autoregressive model of time series is introduced into the noise models.

在信号仿真中，研究了利用二体运动和摄动法计算LEO卫星至GPS卫星星座的几何距离的问题；在信号的误差模型中，研究了电离层时延的IRI2001模型和单层投影模型；讨论了观测误差、多径效应、相对论效应和天线相位中心偏移的误差模型；结合电子测量噪声的具有自相关特性的经验，研究了观测误差的AR模型；结合实测数据分析，讨论了接收机钟差和卫星钟差的误差建模问题。

Error-control coding technology is very important to reduce error probability and improve dependability in satellite communication.

在卫星通讯中，差错控制编码技术对降低误码率、提高通信的可靠性具有非常重要的作用。

This will be the first time ESA has launched a satellite into this orbit, notes Detain.

这将会是第一次 ESA 发射一座人造卫星进入这个轨道之内， Detain记录到。

The Modulation Transfer Function is an essential parameter in satellite imaging system.

MTF是反映卫星成像系统性能的重要参数。

Modulation transfer function is an essential parameter which characterizes imaging quality of satellite optical camera.

1引言调制传递函数是对卫星光学相机成像性能进行评估的一个重要参数，该函数反映了相机的两个重要特性，即所成图像的分辨率和对比度，它是目前评价光学相机空间特性最好的参数[1]。

This is an essential point for the interpretation of satellite remote sensing data.

这是一个重要的一点解释卫星遥感数据。

Though a fictional country, Chernarus is also modelled exactingly on real terrain from satellite imagery.

虽然是个虚构的国家，Chernarus也参照真实的地形和卫星图片建模。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
