A. Petrovsky, A. (author), Doole, M.M. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author), Tomasello, F. (author)The objective of this paper is to raise awareness about the significance of collecting and ensuring the quality of the obstacle data required for the safety of air navigation for both manned and unmanned aviation. This information could be of importance to geodetic, CityGML, 3D model and Building Information Management (BIM) community. With the...conference paper 2018

Doole, M.M. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)The concept of autonomous drone delivery in urban areas has gained a favorable amount of media attention over the past few years. Companies such as Amazon, Uber and Matternet are investigating the use of drones to transport parcels in order to solve the disaggregate delivery (last-mile) problem. This solution could potentially reduce vehicular...conference paper 2018

Maas, J.B. (author), van Gent, R.N.H.W. (author), Hoekstra, J.M. (author)Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...conference paper 2018

Sun, Junzi (author), Blom, H.A.P. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)This paper focuses on estimating aircraft mass and thrust setting using a recursive Bayesian method called particle filtering. The method is based on a nonlinear state-space system derived from aircraft point-mass performance models. Using solely ADS-B and Mode-S data, flight states such as position, velocity, and wind speed are collected and...conference paper 2018

Sunil, E. (author), Þórđarson, Olafur (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Decentralized en-route airspace concepts have been proposed by many studies to increase airspace safety and capacity. Most of these studies, including our own forays into this domain, have used fast-time simulation experiments to explore the benefits offered by decentralization. While simulations are indispensable during the initial design phase...conference paper 2018

Ellerbroek, Joost (author), Inaad, Mazin (author), Hoekstra, J.M. (author)This paper presents an analysis of the potential fuel and emission benefits of implementing Continuous Descent Operations at Schiphol International Airport, from cruise altitude to the final approach fix, for a large scope of aircraft types. Using historical data from on-board sources and ADS-B, fuel-optimal continuous descents are simulated...conference paper 2018

Hoekstra, J.M. (author), Ellerbroek, Joost (author), Sunil, E. (author), Maas, J.B. (author)Both U-space in Europe, as well as UTM in the USA, develop concepts and tools for UAV airspace. Enabling highdensity operations is one of the goals of these studies. Past and recent studies have analysed which factors affect the capacity of a UAV airspace. An improved understanding of this can lead to control methods for capacity management. Two...conference paper 2018

Sunil, E. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)This paper presents a semi-empirical method to determine the maximum theoretical capacity of decentralized airspace concepts. The method considered here, named Capacity Assessment Method for Decentralized ATC (CAMDA), formalizes an earlier approach described in literature, extends it for threedimensional airspace, and also improves the accuracy...conference paper 2018

Dol, C.P. (author), Hoekstra, J.S.C.M. (author)The ageing of European societies and increasing pressure on collective pension arrangements has sparked interest in alternative, more individualised forms of pension provision. Home ownership is regarded as one of these alternatives. Home owners can release housing equity by moving to a smaller owner occupied dwelling or a rental dwelling....conference paper 2018

Sun, Junzi (author), Hoekstra, J.M. (author), Ellerbroek, Joost (author)The aerodynamic properties of an aircraft determine a crucial part of the aircraft performance model. Deriving accurate aerodynamic coefficients requires detailed knowledge of the aircraft’s design. These designs and parameters are well protected by aircraft manufacturers. They rarely can be used in public research. Very detailed aerodynamic...conference paper 2018
