The present application relates to the technical field of integrated navigation, in particular to a positioning method and system based on optical angle measurement and astronomical-inertial integrated navigation. The method first acquires star and navigation satellite images by shooting a star map, and then calculates the attitude of the camera relative to the geocentric inertial coordinate system by identifying and processing the stars, and further determines the coordinates of the navigation satellite in the coordinate system. Through coordinate conversion, the angle information of the navigation satellite relative to the observer in the earth coordinate system is obtained. The optical angle measurement information is fused with the attitude, speed and position information output by the inertial navigation system, the Kalman filter state equation and observation equation are constructed, and finally the real-time high-precision solution and update of the observer's position are realized. The present application combines the accuracy of optical angle measurement, the limited distance reference of astronomical navigation and the autonomous continuity of inertial navigation, effectively improving the navigation and positioning accuracy and reliability under complex environment and satellite denial conditions.

The application discloses a method and device for improving positioning accuracy of a steel taking machine of a heating furnace, and belongs to the technical field of hot-rolling heating furnaces. The method is implemented by refining C values in a mathematical model of the steel taking machine of the hot-rolling heating furnace, obtaining C values of slabs of various widths, and determining advancing or retreating APC strokes of the steel taking machine. The mechanical inertia of the equipment when the steel taking machine is stopped is improved through PLC, so that the steel taking machine is positioned. The slabs of various widths are debugged and functionally improved, so that the positioning accuracy of the steel taking machine can be directly quantified. The application can improve the position accuracy of the steel taking machine and solve a series of problems such as steel spreading and deviation of the heating furnace.
