An attitude sensor for spinning rockets and the associated digital computing procedure have been developed and tested. The measuring system consists of a commercially available flux gate magnetometer and a single solar cell with a fan-shaped acceptance beam. The computing procedure is designed to improve approximations of the rocket aspect angles by successive differential corrections which are derived by a least squares treatment of an overdetermined system of condition equations. Both the measuring system and the computing methods have been found to provide a practical approach for determining rocket aspect. The system is estimated to have been accurate to between one and two degrees in its initial test and to have a potential accuracy of better than one degree.
