Abstract: Doppler Very High Frequency Omnidirectional Range (DVOR) is an internationally recognized high-precision short-range phase angle measurement navigation system. It is usually combined with Distance Measure Equipment (DME) to provide polar positioning(ρ-θ Positioning) for civil aircraft. Among them, DVOR VRB-52D navigation equipment produced by INDRA AWA company is widely used in civil aviation of China, and its market share is in the forefront. Aiming at the case that the near-field monitoring antenna failure of DVOR VRB-52D equipment in a domestic navigation station leads to the shutdown of two computers, this paper discusses the analysis, troubleshooting and countermeasures of DVOR VRB-52D equipment in the near-field monitoring antenna failure.
