Abstract
This paper describes the concept validation process of an onboard inertial platform by means of a motion stage as the low-cost supplementary device for the attitude control subsystem of ISAS/JAXA sounding rockets. The proposed device is a HEXA 6 DOF parallel robot consisting of parallel links with one moving plate to make up a motion stage, aiming at achieving the resolution of changing in its attitude angle is 0.1 degree. In addtion, this device is equipped with a single axis spin table installed on the top of the moving plate to enhance the spin dump/suppressing ability. The flight experiment has been performed January 2020 using S-310-45 rocket with successfully obtained telemetry data enough to conclude that this approach can be one of options for the low-cost attitude control assistant device.
