Hoekstra","doi":"10.2514/1.I010520","DOIUrl":"https://doi.org/10.2514/1.I010520","url":null,"abstract":"AUTOMATIC dependent surveillance–broadcast (ADS-B) [1,2] is widely implemented in modern commercial aircraft and will become mandatory equipment in 2020. Flight state information such as position, velocity, and vertical rate are broadcast by tens of thousands of aircraft around the world constantly using onboard ADS-B transponders. These data are identified by a 24-bit International Civil Aviation Organization (ICAO) address, are unencrypted, and can be received and decoded with simple ground station set-ups. This large amount of open data brings a huge potential for ATM research. Most studies that rely on aircraft flight data (historical or real-time) require knowledge on the flight phase of each aircraft at a given time [3–7]. However, when dealing with large datasets such as from ADS-B, which can contain many tens of thousands of flights, exceptions to deterministic definitions of flight phases are inevitable, due to large variances in climb rate, altitude, velocity, or a combination of these. In this case, instead of using deterministic logic to process and extract flight data based on flight conventions, robust and versatile identification algorithms are required. In this paper, a twofold method is proposed and tested: 1) a machine learning clustering step that can handle large amounts of scattered ADS-B data to extract continuous flights, and 2) a flight phase identification step that can segment flight data of any type of aircraft and trajectory by different flight phases.","PeriodicalId":179117,"journal":{"name":"J.

The discussion is initiated by describing possible threats that the system faces, as well as the specific security services that have to be provided in order to mitigate them. Next, a set of five primal security functions that a federated satellite system has to implement is defined, and an interaction state model is propose to characterize the security state when two federates are interacting with each other. Differences in these security states are then used to define the interaction state machine, which is a transition state diagram that can be used to rapidly identify which security functionality has to be provided in order to securitize an unreliable interaction. Finally, the interaction state model and interaction state machine are applied in a multihop setting where information is relayed through multiple federated satellite system participants. Based on this discussion, the concept of best-effort...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Both methods are based on the Monte Carlo idea of evaluating multiple samples of an initial statistical distribution around the nominal state. However, whereas the graphics processing unit implementation aims at increasing the performances of the classical Monte Carlo approach exploiting the massively parallel architecture of modern general-purpose computing on graphics processing units, the method based on differential algebra is aimed at the improvement and generalization of standard linear methods for uncertainty propagation. The two proposed numerical methods are applied to test cases considering both simple two-body dynamics and a full n-body dynamics with accurate ephemeris. The results of the propagation are thoroughly compared with particular emphasis on both accuracy and computational performances.","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Two-dimensional perspective displays are often used to represent three-dimensional information to humans. Such displays can use different compression rates (actual distance conveyed per unit of screen distance) for identical spatial quantities. An existing data set was used, in which spatial judgments (relative distance, angle, and elevation) were made about the relative location of a terrain point shown on a simulated aircraft synthetic vision systems display. The correlations between compression rates and associated judgment error were then measured. Correlations were computed for average participant judgments as well as for each participant, from which an average correlation was computed. Significant negative correlations were found between compression rates and judgment error for all of the analyzed spatial j...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

These heuristics are designed to run fast, but they often do not promise any guarantee about the solution quality. Inspired by two existing algorithms for scheduling of railway operations, this paper introduces a branch-and-bound-based aircraft routing and scheduling approach with guaranteed global optimality as a real-time decision support tool for air traffic controllers. The performance of the algorithm is benchmarked against two previous approaches: a combinatorial approach using mixed-integer linear programming, and a heuristic approach based on bacterial foraging. The configuration agnostic design of the algorithm makes it suitable for applications: even to unconventional airport layouts. The globally optimal nature of the current solution exhibits a distinct improvement over the respective solutions while maintaining minim...","PeriodicalId":179117,"journal":{"name":"J. Aerosp. Inf.

Analytic comparison with an existing methodology is carried out to highlight superior obstacle-avoidance properties of the proposed strategy. Simulations are carried out in a three-dimensional environment for single and multiple obstacles.
