Abstract : The studies performed were concerned with the antenna constraints which would be placed upon the proposed attitude measurement systems. The three systems under study were: (1) An interferometer, with the baseline on the vehicle itself, consisting of two or more radiators operating at slightly offset frequencies, the phases of which would be compared by the ground station or stations. (2) A system for measuring the polarization of the signal received at the ground and relating this polarization to the orientation of the vehicle. (3) A system which utilizes the amplitude pattern of the transmitted signal to determine the orientation of the vehicle.
