Abstract
Important considerations are given in connection with achieving submicroradian jitter for body-fixed payloads employing inertial reference sensors. The derivation of the requirements, key design aspects, and specifications for important components are treated. The submicroradian-level pointing system for use on the body-fixed telescope (BFT) is described, emphasizing line-of-sight (LOS) jitter application. The pointing subsystem design is described. The BFT is tested on a motion table and shaker table, and compared with a simulation of LOS jitter due to base motion. Performance expectations are verified by the testbed, and are shown to vary from predicted results by less than 10 dB at all frequencies. A submicroradian-jitter stabilization subsystem may be built with qualified components that are presently available.
