The motion of a satellite with respect to a fixed system of coordinates in space has been determined. Formulas are derived which determine the aspect of the satellite axis, and the aspect of a vector perpendicular to the satellite axis. The telemetered data consisted of solar angle measurements in terms of voltage from six sun sensors along the pitch, yaw, and roll axis, and magnetic field measurements from three mutually perpendicular magnetometers. The 7094 computer programs to determine the aspects along with the resulting plots of the desired angles as a function of flight time for different revolutions are exhibited. These plots showed that the satellite was not stable as expected, but a stabilizing trend was noticeable as flight time increased.
