The film uses images captured by the solar and heliospheric observer soho to generate film images for the giant screen , providing audiences with a spectacular sense of actually being there 片中将太阳轨道卫星搜集的太阳影像转为大银幕影像，让观众有身历其境的快感。
Compared with the conventional pictures from geostationary satellites , pictures from polar - orbiting satellites have higher resolution because they fly much closer to the earth 由于极地轨道卫星较接近地面，所以拍摄到的云图分辨率比一般大家熟识的地球同步卫星云图为高。
This paper mainly focuses on the front - end of the leo satellite system based on cdma , presents the system architecture , the algorithms employed hi the system and the implementation 本文研究了整个低轨道卫星cdma传输系统的数字前端，介绍了其结构、算法原理及具体实现。
Also spotted by other skywatchers , the mystery cloud was quickly recognized as a fuel dump from a booster rocket used to place a satellite in geosynchronous orbit 这个画面同样被其他天空观测者发现，很快地，这条神秘的云带被认为是用来发射地球同步轨道卫星的助推火箭脱落燃料箱后造成。
The pentagon ' s defense threat reduction agency ( dtra ) attempted to predict the results of various hypothetical scenarios involving the use of hanes against leo satellites in 2001 美国五角大厦的防恐怖威胁署（ dtra ）于2001年尝试预测高空核爆影响低轨道卫星所造成的各种假设状况，结果相当令人震惊。
In order to transmit an event such as the olympics via satellite , television signals are first changed into radio waves , which are then sent from a station on earth to an orbiting satellite 为了通过卫星传送像奥运会这样的事件，先要把电视信号变成无线电波，然后把无线电波从地面站发射到轨道卫星上。
Chapter 3 proposed a constellation scheme for a regional satellite navigation system . the constellation is consist of geosynchronous satellites and synchronous satellites with elliptical orbit 第三章在分析了适用于构造区域卫星定位系统的卫星轨道类型后,提出了利用静止卫星和同步椭圆轨道卫星构造星座的方案。
According to press accounts , china can use probable low - energy lasers to “ blind ” the sensors on low - earth - orbiting satellites , although whether this claim extends to actua l facilities is unclear 根据新闻媒体的报道，中国可能能够用低能量激光，使近地轨道卫星的传感器“致盲” ，虽然还不清楚这种说法是否涉及实际的设备。
Among his other professional activities , doney serves on the nasa orbital carbon observatory science team and is chair of the ocean carbon and climate change scientific steering group , which is a part of the u . s 唐尼从事许多科学研究，他是美国航太总署轨道卫星碳观测站的科学小组成员，也是海洋碳与气候变迁科学指导小组的主席。
Low earth - orbit satellites have become indispensable for u . s . military communications , gps navigation for smart bombs and troops , and for real - time surveillance . the chinese test highlights the satellites vulnerability 低地球轨道卫星对美国军事通讯、精确炸弹和士兵的gps导航及制导和实时侦察至关重要。中国这次试验凸现了卫星的脆弱性。
