To provide a blocking prediction method for having suitable prediction capable when predicting whether or not blocking will occur on a planned sea route and capable of transmitting amount of inclination needed in bow direction to have communication possible.SOLUTION: A processing unit 11 includes a first step of setting a deviation range by taking into consideration the deviation width in bow direction set before hand to the direction when a satellite is seen from a vessel and a second step of predicting whether or not blocking will occur based on the deviation range in a blocking prediction method for predicting whether or not blocking will occur on the planned sea route to the signal transmitted from the satellite.SELECTED DRAWING: Figure 1
