Abstract
This paper describes an approach to the ADS-B coverage design being undertaken for the mountainous terrains of Bhutan. Existing ADS-B implementation studies have mostly focused on coverage design based on interference criteria. There is a lack of ADS-B coverage design studies in challenging terrain like in the Himalayan kingdom, where about 98% of the land cover is mountains. To account for the unique environment, a physical optics-based deterministic channel modeling methodology is adopted. A radio siting algorithm developed to determine the best location of additional ADS-B receivers is outlined. The effectiveness of the algorithm is demonstrated by applying it to determine the location of additional ADS-B receiver at PARO control zone to improve coverage in areas critical to flight operations. This study will be augmented by analysis of opportunistic ADS-B signal measurements being carried out before the ADS-B receiver network is implemented for use in air traffic management purpose.
