Kurzfassung
In the current remodernisation of the Air Traffic Management, APNT systems based on terrestrial navigation aids are conceived as backup solutions in case of a GNSS outage. In this paper, we address the widely acknowledged problem of degraded geometries in terrestrial ranging systems for aviation. We analyze the impact degraded geometries have on the ill-posedness of the positioning algorithm by means of the condition number. Finally, we propose an approach based on a regularized least squares estimator suitably designed for these specific conditions.
