“…Additionally, these functions were demonstrated in flight trials [4], [15]. Further, a concept of LDACS-based Wide Area Multilateration (WAM) is proposed as one of the surveillance functions [16].…”

“…Throughout the flight campaign, our ENRI prototypes functioned solely as receivers to avoid emitting radio waves, as they were not certified yet via necessary licenses for TX. The LDACS FL signals from the SESAR GS were received and decoded by the ENRI AS in real-time, whereas the RL signals from the SESAR AS were captured and stored by the ENRI GS for later offline analysis for the LDACS-WAM feasibility study [16]. Only FL signals were decoded in real-time because FL signals can be synchronized using the synchronization symbols in the BCCH.…”

The L-band Digital Aeronautical Communications System (LDACS) is a cellular-based broadband, secure digital aeronautical communications system designed to enhance the safety and efficiency of air traffic management (ATM) through the facilitation of innovative ATM paradigms, such as 4D trajectory-based operations (TBO). LDACS is in its final stages of standardization by the International Civil Aviation Organization (ICAO) and the European Organisation for Civil Aviation Equipment (EUROCAE). Furthermore, it has been introduced to not only the aviation industry but also the Internet community in the form of an informational Request For Comments (RFC). Rapidly creating prototypes of an international communications standard by multiple organizations is crucial to the effective deployment of that standard. This approach enables validation and interoperability testing across various countries' prototypes. Therefore, first, we create an LDACS prototype through a software/hardware co-design strategy by Software Defined Radio (SDR) and High-Level Synthesis (HLS). This approach expedites and economically streamlines the development process. Second, we show the alignment of our prototype with the LDACS specification through preliminary and cell entry tests. Third, we demonstrate the efficacy of LDACS' Quality of Service (QoS) and security features via end-to-end IPv6 connectivity and security tests. Finally, the soundness and clarity of the LDACS specification is evidenced via interoperability tests between our prototype and a European counterpart.

“…Passive detection is of interest to civil aviation agencies seeking to track aircraft. These applications typically employ aircraft transponder signals such as Airborne Collision Avoidance System (ACAS) Mode S signals [138], L-band digital aeronautical communication system (LDACS) [139], or the Automatic Dependent Surveillance-Broadcast (ADS-B) messages [52], [140]. The approach in [138] is for ground tracking at an airport, rigidly limiting the scenario to two dimensions, and employs RF over fiber (RoF) in order to centralize the detection and processing functions.…”

In multilateration, distances between an unknown location and several known points are used to determine the location of the unknown point. Papers on algorithms for multilateration, such as time of arrival (TOA), time difference of arrival (TDOA), and angle of arrival (AOA), have proliferated in the literature. These use the same equations, but are often written in a way that hides the underlying geometry and make it difficult to see the similarity in approaches between different papers. This paper provides a review of TOA and AOA-based localization approaches, with a focus on linear positioning algorithms. This paper presents simple and consistent versions of TOA, TDOA, and AOA position equations with intuitive explanations for how those equations relate to the geometry of the localization problem. This perspective can make it easier to implement these algorithms in a way that produces stable results and provides insight into the underlying geometric problem. We also review the literature relating to TDOA and AOA localization algorithms and multistatic radar.
