Abstract:
The Precision VHF Omnirange PVOR consists of an International Civil Aviation Organization ICAO standard VOR that has been modified to transmit additional precision multilobe bearing information on the same channel. A standard airborne navigation receiver with a PVOR converter automatically resolves the ambiguities of the multilobe signal. An unmodified navigation receiver continues to use only the standard portion of the signal with no degradation in performance. Flight tests of the PVOR combined with a four-loop VOR and with a Doppler VOR indicate an improvement in system accuracy of better than 5 to 1. The overall reduction in siting effects is slightly better than that obtained with a Doppler VOR. The multilobe principle provides a potential 13-fold improvement in instrumentation and monitoring accuracy. The system described is a feasibility model. It is recommended that further effort be expended on an engineering model of a complete system, including monitoring and calibration equipment. Author
