Low-Frequency Beacon Signal Strength Determination.

Abstract

Mathematical models and computer programs have been developed which allow the prediction of signal strength magnitudes produced by low-frequency, non-directional beacons commonly used for aircraft navigation aids. In addition, a calibrator has been designed, built and tested which allows quantitative signal strength data to be collected using ground vehicles or airplanes. Good correlation between predications and measurements has been observed. Predications for signal-in-space values can be based either on theory or ground observations. Accuracies typically can be expected to be within 5 dB. (Author)
