本文首先介绍 NOAA 极轨气象卫星和 GMS 静止气象卫星的地面接收设备,重点说明微机实时接收处理系统的构成和特点:1)与接收机联结的接口板是双星共用的(GMS 和 NOAA 卫星共用),用不同软件接收不同卫星的信号。2)系统配备了小型,13.3cm(5.25时),全高,高速,10Mbit/s,大容量310M 字节,硬盘。3)信号采集和显示过程是实时的。4)采集的信号分别是 NOAA 星的全 HRPT 数字信号和 GMS 星的展宽数字信号,S-VISSR。5)具备通用图象处理能力。6)系统是业务化的,自1988.9.15.投入准业务运行以来,一运行是可靠的。7)系统应用兼顾定量的数值处理和定性的图象处理两部分,定量部分精度为:地理定位精度小于5km(未经地面校正),海面温度测量小于1℃。然后介绍卫星遥感资料的处理,应用,效益等方面,例如:东,黄海渔场海温速报,为中央电视台提供海冰实况和预报分析录象等,最后叙述对将来发展的设想。
This paper first introduces the ground receiving equipment of the NOAA polar orbiting weather satellite and the GMS stationary weather satellite, and focuses on the composition and features of the real-time microcomputer receiving and processing system. 1) The interface board connected with the receiver is dual-shared (shared by GMS and NOAA satellites) , With different software to receive signals from different satellites. 2) The system is equipped with a small, 13.3cm (5.25 hours), full height, high speed, 10Mbit / s, large capacity 310M bytes, hard drive. 3) signal acquisition and display process is real-time. 4) The collected signals are the full HRPT digital signal of NOAA star and the widened digital signal of GMS star, S-VISSR. 5) with general image processing capabilities. 6) The system is operational, and since 1988.9.15, one operation has been reliable since it was put into quasi-business operation. 7) The system uses both quantitative numerical processing and qualitative image processing. The accuracy of the quantitative part is that the accuracy of the geolocation is less than 5km (without ground correction), and the sea surface temperature measurement is less than 1 ° C. Then we introduce the processing, application and benefit of satellite remote sensing data, for example, the SSTA for East and Yellow Sea fisheries, the live sea ice for CCTV and the video and so on. Finally, we will describe the future development.
