Abstract : Analyses, laboratory experiments, and flight tests on a precision doppler VOR bearing measurement system are presented. The system incorporates an FM subcarrier to convey the bearing reference. A summary is given of the investigations leading to the selected schemes for modifying VOR station and aircraft receivers. Flight test results at several VOR stations are reported showing substantial improvements in angle accuracy. Compatibility tests demonstrated insignificant degradation in conventional receiver performance due to the modified signal. (Author)
