Satellite communication spot beam coverage edge calculation method based on sensor visual angle

The invention discloses a satellite communication spot beam coverage edge calculation method based on a sensor visual angle, and relates to the technical field of satellite communication simulation. According to the method, from the perspective of the sensor, the earth coverage edge of the satellite communication spot beam is accurately calculated according to the satellite sensor attitude and the satellite attitude, and the beam edge unit observation vector can be established according to the pointing direction of the sensor; after a series of coordinate system conversion, a linear equation and an earth ellipsoid equation are combined for rapid calculation to obtain a space rectangular coordinate of a satellite communication spot beam coverage edge. And directly calculating the latitude and longitude of the intersection point of the satellite spot beam edge and the earth according to the antenna pointing azimuth angle and pitch angle of the satellite and the satellite attitude data. 本发明公开了一种基于传感器视角的卫星通信点波束覆盖
