    摘要: A pose calibration method for an aerospace magnetometer includes the following steps: mounting a magnetometer and a camera on a vehicle body; in the ground state, completely expanding a stretching rod mounted on the vehicle body, and taking photos from multiple angles by the camera in the Earth's full gravity mode; in the near-moon gravity mode, taking photos from multiple angles by the camera; comparing the photos in the Earth's full gravity mode and the near-moon gravity mode to obtain a reference database; and repeating S2 and S3 in an on-orbit state, and comparing the photographing result with the reference database to obtain a length and an angle of the stretching rod. According to the pose calibration method, the photographed structure in the on-orbit state is compared with the reference database to obtain the length and the angle of the stretching rod.
