| 1. | The first thing this satellite needs is a low orbit 卫星的第一道关是需要一条低空运行轨道。 |
| 2. | The same storm caused the atmosphere to inflate and dragged a satellite to a lower orbit prematurely 该次太阳风暴也令地球大气受热膨胀,导致空气阻力增加,使一个星提早跌至较低轨道。 |
| 3. | In the lower orbit , scientists will be able to distinguish surface objects as small as 3 feet 1 meter wide , mcewen said 麦克尤恩说,在这个较低的轨道上,科学家们甚至能够看清火星表面上3英尺1米宽的物体。 |
| 4. | For example , it can be used to drag make - up and solar pressure cancellation of low orbit spacecraft , formation flying and precise positioning of small satellite , repos 同时, mpt也可用于低轨道( 300 500km )航天器的大气阻力补偿,星际航行航天器的主推进,以及星座和小型卫星的编队飞行和精确定位等,具有广阔的应用前景。 |
| 5. | The space station system inosculates the technology of satellite and manned flight vehicle . it can realize manned flight in the low orbit with more reliability , maintainability , expandability and usability 空间站系统融合了卫星和载人飞船的技术,可以长期在空间低轨道上作载人飞行,而且具有较高的可靠性、维修性、可扩展性和实用价值。 |
| 6. | Radio tracking of the trajectory of lunar prospector , which traveled in a low orbit that came as close as seven kilometers to the lunar surface , showed stronger than expected gravity above some of the youngest impact basins 月球探勘者号以靠近月表七公里的距离沿低轨道运行,无线电追踪月球探勘者号的轨迹显示,部份最年轻的撞击盆地上,其重力高于预期。 |
| 7. | According to the characteristic of high vacuum thermal environment in low orbit , it builds the theoretical modeling of the thermal analysis of thermal distortion in optical reflector of antennas system . making use of the results reached by ansys software , it analyzes and compare the stress and distortion of reflector under the static temperature 论文建立了在轨运行空间高真空热环境下的天线镜面热变形分析模型,利用有限元分析软件ansys仿真得到的结果,分析比较了稳态温度场条件下潜望式天线系统反射镜面的应力及变形情况。 |
| 8. | Soon light - weight phones outfitted with high - resolution screen ? which can be embedded in everything from wristwatches to palm - held units ? will be connected to series of low orbit satellites enabling people to talk , send and receive e - mail , or take part in video conferences any time , anywhere 译文:不久以后,装有高清晰度屏幕的轻型电话? ?这种电话能安装在从手表到手持装置等任何东西上? ?降雨一系列低轨道卫星相连,使人在任何时间和任何地点都能交谈、发送和接收电子邮件或参加电视会议。 |
| 9. | Such tdrss system can significantly reduce the use of ground - based monitors as well as increasing medium - low orbit coverage , hence enhance the efficiency of the usage of space along medium - low orbit . “ space target capturing and tracking ” ( stct ) is an important technique in data relay satellite system , and is the preliminary requirement to establish the space link . “ performance of analyzing and simulating on tracking receiver in data relay satellite capturing and tracking system ” plays an important role of stct 数据中继卫星系统是为中、低轨道的航天器与航天器之间、航天器与地面站之间提供数据中继、连续跟踪与轨道测控服务的系统,使用数据中继卫星可以大量减少地面测控站的数量,增大对中、低轨道的覆盖率,有效的利用中、低轨道资源。 “星间目标捕获与跟踪”是数据中继卫星系统的一项关键技术,是建立星间链路的首要条件。 |
