Abstract [en]

We give algorithms for splitting a geographical region into ”approximately flat” rectangular zones. Each zone is assigned a feasible flight altitude, providing simple flight level guidance for future operations of unmanned aerial systems in low-level airspace. We consider a rural scenario with uneven ground level and an urban setting featuring many tall structures. In both cases, our solutions adapt to the underlying terrain or city landscape. In the rural scenario, operating on a fixed altitude within a rectangle allows the drone to stay within the upper limit of 120m while not flying too close to the ground; our objective is to minimize the complexity of the airspace. In the urban case, we aim at minimizing the volume of airspace reserved for drone operations, while allowing overflight over tall buildings in the city. Experiments with real landscape and city skyline data demonstrate output of our solutions with various input parameters.

Abstract [en]

As the interest in drones continues to grow in both commercial and leisure markets, governments around the world are preparing to face the new challenges arising from unmanned operations. Safe and efficient handling of this novel drone traffic warrants an Unmanned Traf-fic Management (UTM) system capable of dealing with the envisioned high traffic densities. In this dissertation, we identify and address several topics critical for future UTM system development, specifically in the areas of airspace and traffic management. Our work on airspace management includes comparing different airspace designs, developing a risk-management concept inspired by performance-based navigation (PBN), and proposing algorithms for establishing a common altitude reference system. Our contributions to unmanned traffic management include comparing different conflict detection and resolution (CD&R) strategies, developing risk-aware routing algorithms, and proposing an approach for planning mass-scale operations with focus on medical use. We obtained these results primarily through quantitative methods, including mathematical modeling, design and analysis of algorithms, and numerical simulations. With this work, we aim to build a strong foundation for the development of future UTM and discuss directions for future research. 

Abstract [sv]

Då intresset för drönare fortsätter att växa både på kommersiella och fritidsmarknader, förbereder sig regeringar över hela världen för att möta de nya utmaningar som uppstår från obemannade flygningar. Säker och effektiv hantering av denna nya drönartrafik kräver ett system för trafikledning för obemannat flyg (UTM) som kan hantera de förväntade höga trafiktätheterna. I denna avhandling identifierar och behandlar vi flera ämnen som är kritiska för framtida UTM-systemutveckling, specifikt inom områdena luftrums- och trafikhantering. Vårt arbete med luftrumshantering inkluderar jämförelse av olika luftrumsdesigner, utveckling av ett riskhanteringskoncept inspirerat av prestandabaserad navigation (PBN) och förslag på algoritmer för att etablera ett gemensamt höjdreferenssystem. Vårt bidrag till obemannad trafikhantering inkluderar jämförelse av olika strategier för konfliktdetektering och -lösning (CD&R), utveckling av riskmedvetna algoritmer för ruttplanering och förslag på en metod för planering av operationer i stor skala med fokus på medicinsk användning. Vi erhöll dessa resultat främst genom kvantitativa metoder, inklusive matematisk modellering, design och analys av algoritmer och numeriska simuleringar. Med detta arbete strävar vi efter att bygga en stark grund för utveckling av framtida UTM och diskuterar riktningar för framtida forskning.
