The High Resolution Telescope and Spectrograph (HRTS) instrument on Spacelab 2 has a stringent pointing stability duration requirement. Therefore an image drift compensation system has been developed which transmits data from solar sensors located within the HRTS to the Instrument Pointing System (IPS) control loop. Internal image drift compensation and a step-rastering capability have also been designed into the HRTS. Solar feature target selection is achieved in real time by using a manual pointing controller and an H-alpha TV slit display in closed loop with the payload specialist. The pointing stability requirement of the HRTS, based on the results of three rocket flights, is compared with the expected IPS performance.
