摘要

RASAT将是土耳其设计和制造的第一颗卫星，计划于2011年发射。RASAT是一颗低地球轨道(LEO)观测微卫星，质量约为100公斤。这次任务的主要目的是利用高分辨率光学成像仪进行遥感。通信子系统是对地观测卫星的主要系统之一。除了下行数据传输外，它还用于遥控/遥测信令。在卫星通信子系统中，主要有五个模块。在调试阶段和下行/上行操作的备份时，使用UHF (Ultra High Frequency) /甚高频(Very High Frequency)模块。主上行链路由s波段接收器提供，主下行链路由机载s波段发射器提供。x波段发射机模块由TUBITAK-UZAY公司的工程师设计和开发，是RASAT通信子系统的实验有效载荷。

Communication subsystem of RASAT

RASAT will be the first satellite designed and manufactured in Turkey and it is planned to be launched in 2011. RASAT is a Low Earth Orbit (LEO) observation microsatellite with a mass of around 100 kg. The main purpose of this mission is remote sensing with use of a high resolution optical imager. The communication subsystem is one of the primary systems for Earth observation satellites. It is used for telecommand/telemetry signaling besides downlink data transfer. In RASAT's communication subsystem, there are mainly five modules. For commissioning phase and as back-up of the downlink/uplink operations, Ultra High Frequency (UHF) / Very High Frequency (VHF) modules are used. The primary uplink is provided by the S-Band receivers and the primary downlink is provided by the S-Band transmitters on-board. X-Band transmitter module, which is designed and developed by engineers at TUBITAK-UZAY, is the experimental payload of RASAT communication subsystem.
