Described are results of the mathematical and systems engineering investigations that were performed on calibration of range instrumentation by means of a calibration satellite. These studies are based on the premise that the instrumentation systems to be calibrated using such a satellite are the MISTRAM and GLOTRAC CW systems and the C-Band and S-Band pulse radar systems. It was further defined, based on present Air Force program planning, that the basic vehicle to carry the calibration payload would be the SATAR (Satellite for Aerospace Research) sponsored by the Office of Aerospace Research. The capabilities of SATAR do not allow the simultaneous inclusion of transponders compatible with all the above systems on one vehicle. These studies have preserved flexibility in techniques within these constraints. (Author).
