“Technology News Express: Recent research has revealed a new method for in orbit calibration of camera parameters. Experts have adopted EFP beam adjustment technology based on LMCCD images for the "Tianhua-1" satellite, effectively improving the positioning accuracy under the condition of no ground control points. After calibration, the vertical disparity of satellite positioning accuracy has been significantly reduced, the overall positioning accuracy has been improved, and the elevation accuracy has also been greatly improved. This achievement provides strong support for research and application in the field of satellite remote sensing.”
