The performance of the ESRO 4 attitude control and stabilization system was investigated using telemetry data collected during the life of the satellite. Factors examined include: spine rate variations, attitude determination, attitude drift, and attitude maneuvers. A thermal expansion model was used which gave good correlation with measured spin rate variations which occurred during and after eclipsing. It was shown that a small improvement in the attitude determination accuracy could be obtained by modification of the criterion used during the mission. Good correlation was obtained between predicted and actual attitude drift and the reorientation errors were found to be consistent with the effects of predicted error sources. (Author)
