The Solar Helispherical Observatory (SOHO) spacecraft is to be placed in a halo orbit around the first Lagrangian point L1 of the Sun-Earth system. The orbit is inherently unstable and consequently requires tight control of delta-V magnitude and direction (25 arcseconds). Attitude control will allow points on the Sun to be observed with a stability of better than 0.8 arcseconds, while tracking the Sun spin axis with a (1 minute) stability of 18.9 arcseconds, in the presence of payload disturbances of 0.02 nms. The soho mission is outlined and the spacecraft and attitude system are described. The control law design adopted to meet the stringent pointing required is examined.
