| Abstract: | Multichannel Scan Imagery Radiometer is one of the primary loads in Fy-4 meteorology satellite. The working state of his scan mirror will affect the quality of the nephogram from FY-4 satellite. According to the working principle of the scan control system, the factor that affect on his working reliability is analyzed. And by using Fault Avoidance and Fault Tolerance technology the influence is eliminated in order to keep the working stabilization of the scan mirror. The results show it is very satisfactory. |
