多路高速遥感数据记录快视与格式化系统设计与实现

Design and Implementation of Recording,Quick-look and Formatting for Multi-channel,High-Code-Rate Remote Sensing Data

针对亚米级分辨率商业遥感卫星吉林一号A星数据传输的多通道和高码速率特点,以及数据记录、快视和格式化处理的需求,采用"平台+插件"的技术体制,以通用的服务器作为计算平台,以商用GPU卡作为数据并行处理的加速硬件,以插件式的思想设计系统软件模块。系统已在机动式遥感接收站中得到了验证和应用,取得了较好的效果。结果表明,系统设计在硬件方面具有一定的通用性,软件方面具有一定的可扩展性。

In view of the characteristics of multi-channel and high-code-rate data transmission and the requirement of data recording,quick-look and formatting for sub-meter high resolution commercial remote sensing JILIN-1 A satellite,this article adopts the technology system of ＂Platform ＋ Plugins＂,and uses general server computer as the computing platform,and uses commercial GPU as acceleration hardware of data processing parallelly,and designs the software modules with the idea of plug-in type.This system has been verified and applied in a certain mobile remote sensing data receiving station,and achieved a good result.The practice indicates that the design of hardware has definite generality,and the design of software has definite extendibility in this system.
