HJ-1A/1B卫星远程播报系统的实现

Research and Implementation of Remote Broadcasting System of HJ-1A/1B Satellite

基于环境与灾害监测预报小卫星星座中的HJ-1A、1B卫星遥感数据,提出一种卫星影像数据与矢量数据在远程播报系统中快速叠加匹配的方法与技术流程。在此基础上,实现了HJ-1A、1B卫星宽覆盖CCD相机的数据远程播报。系统测试表明,远程播报系统对HJ-1A、1B卫星数据空间定位准确,数据处理速度快,满足远程播报实时显示数据的要求。

The Satellite Data Remote Broadcasting System is a kind of presentation system which is used to display and monitor the remote sensing satellite data.At present,remote broadcast system can only display data with moving window mode and cannot overlay display of satellite data and vector data.The paper analyzed the data characteristics of HJ-1A and HJ-1B and proposed a technical process of quick overlay algorithm of satellite image with vector data in the Remote Sensing Satellite Broadcast System.Based on this,the remote broadcast of HJ-1A,1B satellite data on wide-coverage CCD camera is realized.System test results indicate that,for the HJ-1A and 1B data,the Remote Broadcast System achieved the accurate spatial orientation and fast data processing,and met the requirements of data real-time display in the broadcasting system.
