通讯卫星

Telstar, the first satellite to carry TV broadcasts was launched.

通讯卫星，首枚电视转播卫星被发射。

Wireless' communications took a giant leap forward in 1962 with the launch of Telstar, the first satellite capable of relaying telephone and satellite TV signals.

1962年Telstar通讯卫星的发射使无线通讯技术跃进一大步，该卫星为首颗能够传送电话和电视信号的卫星。

Today, many, many telephone users regard international calls as routine, and overseas service, thanks largely to underseas cables and communications satellites , has undergone extraordinary improvement.

今天，许许多多电话用户对国际长话已习以为常了，全球通讯服务的极大改善主要是由于海底电缆和通讯卫星。

The International Telecommunications Satellite Organization, usually referred to as Intelsat, is responsible for all international nonmilitary satellite communication.

国际通讯卫星组织，又称Intelsat，从事所有全球非军事卫星通讯服务，另外还对一些国家提供国内通讯服务。

It is concluded that we can make a communication constellation to become satellite communication web. We then calculate the azimuth, elevation and distance between the two links satellites by using STK.

再利用STK卫星模拟软体，算出气象观测与通讯卫星星系分别应用卫星之间的方位角、仰角及距离关系。

For hundreds of millions of years, turtles have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings down to the water's edge lest they become disoriented by headlights and crawl towards a motel parking lot instead.

在数亿年前的时间里，海龟一直在挣扎着离开大海道海滩上产卵，时间远远遭遇自然纪录片的赞扬，或全球定位通讯卫星和海洋生物学家的追踪，又或者志愿者们用手把幼龟放在海边以避免它们受到光线的影响迷失方向，爬向汽车旅馆的停车场。

"Typically they move in geosynchronous orbit s about 22,300 mi (35,900 km) above the earth and operate at frequencies near 4 gigahertz for downlinking and 6 GHz for uplinking."

&典型的通讯卫星位于地球同步轨道，约在地球上方35，900公里处，操作频率向地传输4吉赫，向上传输为6吉赫。&

Based on the convolutional coding and decoding, an implementation with retired communication satellites is brought up for use in transmitting the buoy's position information.

提出了一种应用于基于退役通讯卫星的浮标定位信息回传通讯系统的删余卷积编解码方案。

Though geostationary satellites are not the only type of communications satellite,they are certainly the most important at the present time,and they are used in many different ways.

虽然同步卫星不是通讯卫星的唯一的种类，它们无疑是当前最重要的，而且被以不同的方式应用着。

China's plan to cut energy intensity by 20 percent and pollutant discharges by 10 percent between 2006 and 2010 is a case in point.

中国计划在2006年到2010间降低20%的能源强度和减少10%的主要污染物排放，就是一个这样的例子。
