Abstract： The DVB-S is a new digital satellite broadcasting technology which meets the industrial standard. Based on this technology，China Meteorological Administration built up a low-cost，wildly-applied satellite remote sensing data sharing platform. The users can acquire the near-real-time satellite remote sensing data from US EOS，NOAA and Chinese FY satellite series. Due to the signal disturbance and other reasons，some received data have lots of abnormal data，which influence their utilization. Considering the multiple receiving stations in the DVB-S system，there would be lots of overlapped areas in their receiving range. A method for modifying the abnormal data in the MODIS 1B swath image by using the correspondent pixels in the overlapped area is introduced in this paper. Its key steps include image selection，overlapped area matching，abnormal data replacement etc.， and the automatic data processing code is realized by using Visual C++.
