A Transitional Design Study of the Position and Azimuth Determining System (PADS).

Abstract

This report summarizes the results of a Position and Azimuth Determining System (PADS) transitional design study conducted to provide significant operational reliability, maintainability, and human factors engineering advancements over the prototype PADS. Included among the results of this effort are the elimination of the Velocity Reference Unit (VRU) used in the prototype PADS (thus reducing the prototype weight by more than 50 percent), a preliminary design of a PADS pallet, and a new power supply design which provides the PADS the added flexibility of full-time operation in an OH-58A Light Observation Helicopter. In addition, qualification tests were performed on the PADS unique 32-speed azimuth resolver, and the Inertial Measurement Unit (IMU) calibration equations were reviewed.
