Feasibility Assessment of LDACS-Based Wide Area Multilateration

In this paper, an LDACS-based wide area multilateration approach is proposed as a passive cooperative surveillance alternative for civil aviation. Firstly, the underlying concept is introduced and a detailed proof of concept analysis carried out. The suitability and limitations of the LDACS airborne transmission for passive surveillance are then assessed, in particular in terms of the achievable update interval, aircraft identification capabilities, and time delay measurement precision. The underlying analysis and preliminary simulation results support the feasibility of the LDACS-based wide area multilateration functionality.
