The development, test, operation and flight performance, of an attitude control system (ACS), and the refurbishment and launch of a payload are described. The system is applied in the German SN (supernovae) 1987A sounding rocket mission. The ACS comprised an inertial platform with a star tracker and two stellar TV cameras with ground based interactive telecommand for update and fine pointing. The ground and flight telecommand systems are based on the 8052 and 8031 microcontrollers respectively and provided precise offsets for: the automatic mode control, the facility for inflight corrections and the remote selection of redundant operational modes.
