摘要
高分辨率遥感卫星星上载荷原始数据率不断提高,如何将高速载荷数据传输至后端数据处理设备已成为遥感卫星载荷接口设计的关键。在研究高速串行/解串(SerDes)收发器件TLK2711工作原理的基础上,提出了高速串行载荷数据传输接口的设计方案。通过在某卫星星载数据传输系统中的首次应用,实现了星上2Gbit/s的高速串行数据传输,工程试验和在轨验证表明了接口设计的正确性和可靠性,可为其它星载高速数据传输接口设计提供借鉴。
The payload data of high-resolution remote sensing satellite is increasing rapidly, and how to transmit the high-speed data to the posterior processor is of the first importance in the design. According to the technique specifications and characteristics of SerDes TLK2711, a design of high-speed serial data transmission interface is proposed. The high-speed serial transmission interface is first applied in a 2Gbit/s on-board data transmission system. The results of the engineering experiments and on-orbit test indicate that the design is correct and the transmission of the payload data is reliable. The experience can provide a reference for the design of other high- speed data transmission interfaces.
