OPTICAL CALIBRATION OF THE U. S. NAVAL SPACE SURVEILLANCE SYSTEM
Abstract
A project was initiated in the spring of 1960 to calibrate the Space Surveillance System by means of ballistic cameras. The principle behind this calibration is a comparison between the positions of the Echo balloon as determined by radiofrequency reflections of the Space Surveillance System and as determined by photographs against a star background. The preliminary results show that all stations have zero errors of less than 0.1 degree at the zenith. A second error having a standard deviation of about 0.05 degree is due in part to the limited precision of measurement used. The report describes the work done prior to the second phase of calibration, that phase leading to a much higher precision.
