| Abstract: | The FY-2 satellites are a series of geosynchronous meteorological satellites,which is instrumented to observe high-energy particles and solar X-ray fluxes except for meteorological observation.The satellites carry the spatial particle detector and solar X-ray detector.The solar X-ray detector has 10 energy channels which range from 4keV to 100keV to detect the solar X-ray fluxes.Additionally,these X-ray detection data can be used to do some early-warning of space environment disasters.In this paper,we introduce the technique of processing and displaying of FY-2 satellite space environment data.It is also introduced the way to get the shortwave communication LUF(Lowest Usable Frequency) and the ionosphere D-region absorption by using X-ray detection data.A forecasting model of LUF was designed based on the FY-2 X-ray detector data. |
