Paper Abstract

A pointing/roll mechanism for the Ultraviolet Coronagraph Spectrometer (UVCS) is presented along with a description of the mechanism control algorithm. The mechanism, operating in space, will angulary position the 2.1 m long, 0.7 m diameter UVCS instrument in pitch and yaw, within a 54 arc-minute half-angle cone, also allowing it to rotate +/- 179.75 degree(s). After considerable design effort, an optimum mechanical solution was achieved which meets all scientific requirements as well as weight, volume, and power budgets. Evolution of the mechanism is presented along with the design status.
