ActiveTechnology specification for geometric calibration of 1:25000 1:50000 optical mapping satellite
1:25000 1:50000光学测绘卫星几何检校技术规范
Application Summary AI generated
This standard specifies the technical requirements and procedures for geometric calibration of optical mapping satellites producing 1:25,000 and 1:50,000 scale imagery. It is applied in the aerospace and surveying industries to ensure satellite sensors achieve precise geometric accuracy for topographic mapping, land surveying, and geographic information system (GIS) data collection. The standard is used during satellite in-orbit testing, routine calibration, and image quality validation to correct distortions and align sensor parameters with ground control points.
