Abstract:

According to the factors such as topography, earth curvature, headspace blind zone and equipment performance,theoretical coverage of ADS-B ground station is calculated. Based on ADS-B data, Lambert projection method is used to project the generation algorithm of concave hull. Based on measured data, the coverage of ADS-B under different layers of height is calculated. An ADS-B continuity calculation method is proposed to calculate the leakage rate and continuity level. Results show that the proposed method can provide theoretical maximum coverage under the influence of terrain shelter and can be used to assist ADS-B ground station's location decision.

Key words: ADS-B, coverage, Lambert projection method, generation algorithm of concave hull
