卫星多路信号收发端机的设计

概述了卫星通信的特点，论述了卫星特种多路信号收发系统的设计。此收发端机是一个将光纤通信技术应用于卫星地测信号传输的设备，其作用是将卫星地测设备中的多路检测信号通过光纤系统传输到远处的控制中心进行检测，以改善卫星姿控系统监测信号质量。此方案与现今已采用的一些方案相比，在系统易用性、可靠性、安全性和降低软硬件投资等方面具有相当大的优势。同时由于采用时分复用及解复用技术，该收发端机传输信号量大、体积小，因此具有极强的需求背景。

Transceivers for Satellite Multichannel Signals

The features of satellite communications are overviewed, and the design of special transceiver system for satellite multichannel signals is described. This transceiver employs optical fiber communications technlogy in the transmission of satellite earth telemetering signals. Its function is to transmit the multichannel signals detected by satellite earth telemetering apparatus through optical fiber system to the remote control center for detection, so as to improve the monitoring signal quality of the satellite posture control system. Compared with some existing schemes the present transceiver has such advantages as easier usage, higher reliability, better security, lower cost. Furthermore owing to use TDM and D-TDM technology the transceiver features larger traffic, smaller volume, and has better demand prospect.
