Corona Satellite Calibration Targets
The Casa Grande Photogrammetric Test Range is a test range established in the mid-1960s to test the dynamic performance of aerial survey cameras. The range consisted of 272 concrete calibration markers embedded into the Earth's surface in and around Casa Grande, Arizona, United States. The markers are commonly (and erroneously) believed to have been used to aid camera calibration for the US Central Intelligence Agency's Corona spy satellite program; in fact, they were used as references for aerial surveys through photogrammetry.
