轉發通信衛星 的英文怎麼說
中文拼音 [zhuǎnfātōngxìnwèixīng]
轉發通信衛星
英文
repeater communication satellite-
Ncaps is a novel satellite navigation system presented by scientists of cas recently, which is based on the prin ciple that the land control station transmits the navigation signals via communication satellites, other than special navigation satellites, to the ncaps receivers, in which the received signals are processed to obtain its detailed positioning information
空基導航系統代表有美國的gps和俄國的glonass衛星導航系統。 ncaps系統是我國科學家最近提出的一種新的衛星導航系統。其主要原理是：地面控制站利用通信衛星（而不是專用的導航衛星）轉發導航電文給接收機，接收機利用導航電文解算出本地位置。Sinosat - 2, mainly developed and manufactured by the chinese academy of space technology, weighs about 5. 1 tons and has 22 transponders
由中國空間技術研究院開發研製的「鑫諾二號」通信衛星重約5 . 1噸，星上載有22個轉發器。Entering a geosynchronous transfer orbit. sinosat - 2, mainly developed and manufactured by the chinese academy of space technology, weighs about 5. 1 tons and has 22 transponders
由中國空間技術研究院開發研製的「鑫諾二號」通信衛星重約5 . 1噸，星上載有22個轉發器。Its main function is to amplify and transmit the upconvertor ' s signal. it is applied to various kinds of ground equipment and satellite transponder. there was captured by foreign brand basically in the market of mobile communications in our country
眾所周知，功率放大器模塊是微波通信發射機的重要組成部分，它完成對上行鏈路信號的放大發射功能，廣泛的應用於各種地面設備和衛星轉發器中。On - board processing ( obp ) is an important direction in satellite communications, where on - board conversion from fdma to tdm is very useful in raising channel efficiency and decreasing cost of earth stations. basing on extensive research of the fdma ? dm conversion, this thesis proposes a new way for such conversion, i. e. fdma ? wtdm conversion, which is based on a china invention patent ? a time division multiplexing transmission technique for band - limited signals
星上處理是衛星通信技術發展的重要方向，其中星上頻分多址至時分復用（ fdma - tdm ）多址/復用方式的轉換是一個研究熱點，因為它能用於構成一種通道利用率很高、地面站成本很低的fdma / tdm體制的衛星通信系統。分享友人
