This report discusses the design of a servo controlled positioning system for remote control positioning of inertial sensors while under high acceleration test in a centrifuge. A rotating fixture and an electronic control panel was built for this purpose, with two modes of operation. The fixture can be positioned with an accuracy of 0.05 degrees and a resolution of 0.01 degrees, or it can be maintained in a constant velocity mode at rates from 1 to 16 degrees per second. The velocity loop was implemented as a phase locked loop, and the command rate is entered as a frequency - from a function generator or a frequency synthesizer. The position loop employs a pick-off resolver for sensing position and a control resolver for entering the command position. The paper presents the entire design picture, including a consideration of design alternatives, and servo and electronic circuit design. Photographs of the system in operation are shown in the appendix.
