AbstractThe application of RF monopulse sensing techniques for communications satellite attitude determination was investigated. An engineering model of a two channel 6 GHZ spaceborne RF monopulse attitude sensor capable of measuring roll, pitch and yaw was developed. RF attitude sensing provide attitude measurements compatible with the requirements of future body and spin stabilized satellites employing narrow antenna beams without recourse to mechanical motion. Sensor alignment errors are greatly reduced since the sensing element is a physical part of the antenna array. Troublesome operational difficulties of sun and moon interference are also eliminated. Yaw angle is determined through measurement of roll and pitch angle to two separated beacons. Experimental results including a preferred design, reflecting future stabilization and long life requirements are presented.
