Abstract In this thesis a computer model for predicting the radiated fields and system errors of the Conventional Very-High-Frequency (VHF) Omni-directional Range (CVOR) and the Doppler VHF Omni-directional Range (DVOR) systems was developed and validated. This software model is based on the Uniform Geometrical Theory of Diffraction (UTD) and can predict the aforementioned fields and errors for different CVOR/DVOR transmitting station configurations. By integrating the model into an existing computer model namely the Ohio University Navaids Performance Prediction Model (OUNPM), a software which predicts the performance of Instrument Landing Systems (ILS) and CVOR/DVOR systems in multipath environments, an improvement in the accuracy of the CVOR/DVOR model of the OUNPPM is achieved. The improved CVOR/DVOR error prediction model of the OUNPPM presents an accurate and inexpensive means for siting CVOR/DVOR system ground stations.
