Test ranges for metric calibration and validation of high-resolution satellite imaging systems

摘要

Metric test ranges for satellite imaging systems have photo-identifiable features with surveyed coordinates. Images of these test ranges are used to determine calibration parameters and to test system accuracy. The size of the test range, layout of the ground control points (GCP), and choice of photo-identifiable features determines the utility of the test range and the accuracy of calibrations derived from it. In this paper, the historical development of test ranges is traced for IKONOS?, as well as the application of those ranges verifying design requirements, improving calibrations, and testing system accuracy. Lessons learned regarding ground control points also are discussed. Test ranges used for IKONOS will be exhibited and the utility of those ranges for various calibrations discussed.
