THE OBSERVATION AND COMPUTATION OF REENTRY TRAJECTORIES WITH THE AIRBORNE ASTROGRAPHIC CAMERA SYSTEM.
Abstract
A detailed theory is presented for computation of reentry trajectories. The theory is intended for application to an airborne range facility consisting of two aircraft. Such a facility, the Airborne Astrographic Camera System, is described, as are the fundamental principles of data acquisition by this system. The observational techniques developed for the system permit the recording of stars of photographic magnitude +6.5 with exposure times of 0.2 second. Techniques for rapid identification of comparison stars are presented. A modified 12-constant plate reduction theory is employed with excellent results in airborne applications. A complete data-reduction flow diagram covering film processing and measurement to final data product is presented, as are the detailed FORTRAN computer programs developed for the reduction and analysis of all spatial reentry trajectory data gathered by the system.
