THE DEVELOPMENT OF AN AERIAL CAMERA WITH CELESTIAL ORIENTATION
Abstract
An aerial camera system which records an image of the sun or other celestial object simultaneously with a terrestial photograph was developed. The adition of precise astronomical mesurements serves to counterct the unfavorable accumulation of errors in the determination of orientation parameters for extended aerial triangulations. The cmera has two 100-mm focl length, f/5.6 lenses incorporated in a camera body in such a way that the respective fields of view are diametrically opposed. A pulse opeated shutter system provides synchronization of exposures within .001 second for exposure durations of .010, .005, .003 or .002 second. The ocrrence of exposure is determined to .050 second as part of the astronomical measuremens. (uthor)
