The invention discloses a probability distribution limit value-based satellite constellation frequency interference avoidance method, which comprises the following steps of: dividing a visual airspace into a plurality of closely adjacent regular hexagonal cell units Ci with smaller areas, connecting the centers of the cells to form a triangle, representing the due north direction of the visual airspace by using a 0-degree azimuth angle, and representing the normal north direction of the visual airspace by using the 0-degree azimuth angle in an anticlockwise direction; the northwest direction is represented by a 90-degree azimuth angle, the northwest direction is represented by a 180-degree azimuth angle, and the northwest direction is represented by a 270-degree azimuth angle. According to the method, aiming at the situation that satellite communication links are established by using the same frequency band between satellite constellation systems and large same frequency interference probability exists, the i
