查询词典 satellite

Satellite in elliptic orbit has a low velocity near apogee and will flight over a particular geographical area for a substantial part of its orbital period ("apogee dwell").

由于运行于椭圆轨道上的卫星在其远地点附近有较长的停留时间，如果选择轨道远地点位于覆盖区域上空，则采用椭圆轨道卫星星座以进行区域性覆盖以取得很好的覆盖效果。

But, the energy that fuel wastes when emissive satellite should be a calm value, it and consult the choice of content did not concern.

可是，发射卫星时消耗燃料的能量应该是一个定值，它和参照物的选择没有关系。

This method provides an alterative way to obtain energy spectra of precipitating particles, and may also act as the complement of the lowertimeresolution limitations of satellite energetic particle observations. It is of high value in both academic and applied fields to establish models of space environment disturbance.

该方法开辟了获取沉降粒子能谱特征的一条新途径，可以弥补卫星能量粒子观测数据磁地方时分辨率的不足，对于建立空间环境扰动模式具有重要的学术意义和应用价值。

We study the effect of the solarcycle and geomagnetic activity on the composition and their maximum positions of the ring current ions by using the energetic particle data obtained by MICS instrument on board CRRES satellite and other research results of AMPTE.

根据CRRES卫星上MICS离子成分探测器的观测资料以及前人有关AMPTE卫星的观测数据，研究了地磁活动和太阳活动性对环电流成分以及各种环电流离子的最大通量位置的影响。

Proton events in general only occur in SAA region while electron events appear at both SAA and polar regions.Electron flux of 0 5～2 0?MeV in polar regions is dominant over that of 2～15?MeV,while at SAA,fluxes from the two channels are about the same.There is a close correlation between energetic particle radiation inside and outside the satellite.

与现有理论模型和国外大致相同轨道上的空间高能辐射环境直接观测资料对比还表明，卫星舱内的辐射与舱外的空间辐射环境是完全相关的，积累的有关资料不但是航天设计和环境应用研究所需的重要参量之一，也是空间物理基础研究特别是辐射带研究的重要数据。

The other satellite ephemeris should be correct.

但是其他卫星的位置是正确的。

Then comparisons of calculating of satellite coordinate with broadcast ephemeris and with precise ephemeris are made.

根据导航电文中的广播星历和IGS提供的精密星历对GPS共视比对结果中的几何时延误差进行了改正。

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。

The ephemeris of satellite, data format, products and function of IGS and application combining GPS and GLONASS are discussed.

讨论了卫星的星历、数据格式、 GPS 和 GLONASS 的综合应用。

Ephemeris data are broadcasted by the Satellite every 30 sec, over the duration of 30 sec.

我不反驳，全球定位系统卫星信号的需要，这是显而易见的。

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