Doppler VHF Omnidirectional Radio Range (DVOR) plays a critical role as a key component of Ground Equipment for Aircraft Navigation (GEAN).
Doppler VHF Omnidirectional Radio Range (DVOR) plays a critical role as a key component of Ground Equipment for Aircraft Navigation (GEAN). So far, little research has addressed the question of how to use Digital Twin (DT) for GEAN. Given that there is a notable paucity of empirical research specifically focusing on the DVOR data acquisition method and Virtual Reality (VR) teaching technology. The specific objective of this study is to explore the application of DT and VR teaching in DVOR. Additionally, this research specifically focuses on the VRB-52D type of the DVOR system. In this study, a novel real-time data acquisition algorithm is proposed to implement The Real-Time Data-Driven Equipment Health Monitoring Subsystem (RTDEHMS). Furthermore, fault logic rules for DVOR are proposed for fault simulation to implement The Virtual Simulation Teaching Subsystem (VSTS). This study not only addresses how to remotely monitor the operational status of DVOR but also resolves the limited opportunities for Communication, Navigation, and Surveillance Equipment Maintenance Personnel (CNS Personnel) to engage in the practical operation of DVOR during their training process. With this system, CNS Personnel can efficiently manage DVOR, and it can also help students learn about DVOR quickly. Finally, an offline survey provided quantitative data from 40 participants. The results of the survey show that almost all participants are satisfied with the system. This research provides a timely and necessary study of the DT application on the DVOR. This study not only confirms the possibility of DT system for GEAN, but also the proposed fault logic construction method is applicable to other GEAN. This study also provides practical experience in modeling, data collection, and interface standards for GEAN, facilitating the standardization and collaboration of GEAN. It provides essential technical support for modern aviation ground support.
