The invention discloses a satellite area visibility judgment method, a mapping range generation method and related devices. The satellite area visibility judgment method comprises the following steps: acquiring a visible mapping range of a selected area; the visible mapping range is the position range of the target satellite when an included angle formed by the target satellite and a sample position point in the selected area meets a visible elevation angle threshold value; matching the position coordinates of the target satellite with the visible mapping range; and when the position coordinates of the target satellite are matched with the visible mapping range, determining that the target satellite is visible in the selected area. According to the embodiment of the invention, the visibility judgment can be realized only by obtaining the visible mapping range obtained through preprocessing in the actual judgment process and performing simple matching in combination with the position coordinates of the target
