Balloon-Borne Three-Meter Telescope for Far-Infrared and Submillimeter Astronomy. Semiannual Status Report No. 6, March 1-August 31, 1986

摘要

The study and revision of the gimbal design of the Three-Meter Balloon Borne Telescope (TMBBT) is discussed. Efforts were made to eliminate the alignment and limited rotation problems inherent in the flex-pivot design. A new design using ball bearings to replace the flex-pivots was designed and its performance analyzed. An error analysis for the entire gondola pointing system was also prepared.
