| Outline of Final Research Achievements |
Precise pointing control was carried out for a long truss structure fixed with main body. The pointing was controlled by the artificial thermal expansion of truss members at the bottom of truss (fixed side). Elastic hinges were introduced to the truss in stead of pin joint because there is no gap in elastic hinges so that hysteresis of the mechanism was expected to be suppressed. We applied the pointing control system to a 4m extensible truss. As a result, the precise pointing accuracy, 1 arcsecRMS, and movable range, 50 arcsec, were confirmed through experiments.
