The application belongs to the field of positioning, and particularly relates to a submerged load distributed ultra-short baseline positioning system and a positioning method. The application discloses a submerged load distributed ultra-short baseline positioning system and a robust positioning method thereof, which effectively overcomes the problem that the positioning results of a traditional ultra-short baseline positioning system are inconsistent under limited observation space and different array patterns. By arranging acoustic elements at multiple positions on the surface of a submarine, a distributed acoustic array is formed, and the observation space of the submarine is expanded. Meanwhile, a robust positioning method is proposed by introducing azimuth constraints, and the robustness of the acoustic positioning result to array changes is enhanced. Through the application, the observation of the acoustic array on the submerged load to a target in the whole space can be realized, and stable positioning accuracy can be maintained when part of the acoustic elements fail.

This invention proposes an on-orbit autonomous geometric calibration method and system for wide-field-of-view optical remote sensing satellites. The method includes: camera imaging and transmitting the captured images to an on-board calibration type autonomous identification module; the on-board calibration type autonomous identification module, combined with satellite orbit and attitude data, determines whether the camera's field of view simultaneously images deep space and the ground; if both exist simultaneously, the Earth's edge is extracted as the boundary between stars and landmarks to delineate their distribution areas; if not, the calibration point type is explicitly determined to be either a landmark or a star; based on the calibration point type, the corresponding image is transmitted to an on-board stellar autonomous calibration module or an on-board landmark autonomous calibration module, and geometric calibration parameters are calculated; the calculated calibration parameters are transmitted to an on-board information processing unit for satellite imaging. This invention ensures the geometric calibration accuracy across the entire field of view of the camera; it avoids the process of transmitting satellite images down to the ground for calculation, thus improving the real-time performance of the calibration parameters.
