The invention discloses a frequency interference avoidance method based on ground station pitching azimuth angle division, which comprises the following steps: dividing any ground station visual airspace into smaller cell units by taking a regular hexagon as a grid, closely arranging the cell units, arranging the centers of all the cells in a triangular shape, representing the true north direction by 0 degree of azimuth angles, representing the true east direction by 90 degrees of azimuth angles, and representing the true east direction by 90 degrees of azimuth angles; 180 degrees represent the south direction, the polar axis length represents the elevation angle range, and the coordinate center point represents the position right above the ground station, namely the elevation angle is 90 degrees. In the invention, a communication link uses two satellite constellation systems with the same frequency, if the communication link serves the same region, the same-frequency interference with a large probability exi
