Abstract
A semi-active gravity gradient attitude stabilization system (SAGS) providing active pitch control and semi-passive roll/yaw control has been developed. The design and development of the SAGS controller for space flight test on the NASA developed PAC secondary payload spacecraft are described and performance predictions are presented for the first flight test scheduled in August 1969. Initial in-orbit performance of Delta PAC-1 is summarized.
