Abstract:

This report covers the design, development, and field testing of a wide aperture digital vor system. The vor ground station is in the form of 8 crossed baseline pairs of interferometers. Each of the interferometers pairs is energized successively by a set of pulses and phase shifts. The airborne receiver decodes the signals from each of the interferometers. This set of measurements on each axis permits complete resolution of ambiguities and the precise calculation of the angle with respect to the station. The objective of this work was the development of a system that would significantly reduce magnitude of siting errors, provide greater accuracy and utilize digital techniques to simplify processing. Field tests of the feasibility model indicate it is a high performance system capable of achieving an order of magnitude improvement in both site error reduction and in accuracy compared to present vor systems. The measured accuracies were 0.11 deg standard deviation. Author
