Abstract

Abstract: Abstract：9 degree of freedom motion simulator (9DOFMS) is the key equipment for calibration of cameratype rendezvous & docking sensor (CRDS) in spacecraft rendezvous and docking guidance navigation and control (GNC) subsystem, and it must be with high relative position precision. To meet this demand, the components of errors impacting this system’s integral indexes are analyzed systemically in this paper. At first, the relationship and interactions among the components of system errors are analyzed. Then the error model is built. By decomposing and redistributing the systematic precision index, 9DOFMS design fulfills the precision requirements.

Key words: Keywords：9 degree of freedom；motion simulator；relative position precision；error analysis, index decomposition
