The invention discloses a satellite beam coverage deduction method based on an on-orbit satellite data resource pool, which comprises the following steps: step 1, associating TLE data, UCS data and Satbeam data to obtain the on-orbit satellite data resource pool: step 2, if a measurement value of a residual error greater than 3 sigma is found, considering that the point is an outlier point, and removing the outlier point; step 3, reading the latest orbit position information from the in-orbit satellite data resource pool after the outliers are removed, and performing orbit deduction through an SGP4 or SDP4 orbit model; 4, predicting the visible time of the NGSO satellite and the earth station; and 5, when the satellite and the earth station are visible, reading the beam coverage information of the satellite, calculating the beam coverage area of the satellite, and judging when the earth station is covered by the beam of the satellite. According to the method disclosed by the invention, the time of covering th
