Advance Research in Guidance,Control,and Instrumentation.

摘要

The report deals with two subject areas; (a) Navigational System Optimal Integration,and (b) Stabilization for Precision Pointing and Tracking. Under the first subject area a theoretical investigation was conducted on the possibility of using all of the navigational aids (DME,VOR,TACAN,inertial systems,Air data systems,etc) aboard aircraft to improve the navigational position accuracy of the vehicle. This investigation resulted in the development of a Kalman filter for using these inputs and an estimation of the computer size needed to perform the task of giving a more accurate position location of the aircraft. Data was obtained from NASA on DME and VOR test data and used in the program and Kalman filter developed under this work effort. The results obtained showed that for the data used the position of the aircraft can indeed be more accurately determined. Under the second subject area a design procedure and design modification for the particular instrument investigated. The primary effort was concentrated on the pointing control loop and the tracking control loop. (Modified author abstract)
