The visible image of FY-2 Geostationary Meteorological Satellite is produced by multiple sensors in the same time, so image has higher resolution. The images produced by multiple sensors are not exactly the same because of the sensors’ differences. This paper introduced several methods to calculate the difference and to adjust the satellite by remote commands and decrease stripes of multi-sensor imagery. The results show that it is correct and the image quality is greatly improved after the adjustment. These methods are also useful to decide when and how to adjust the VISSR while the satellite is on orbit.
