“…In the "Concept for Urban Airspace Integration DLR U-Space Blueprint" paper, the DLR (German Aerospace Center) suggests a system to manage airspace at high-density traffic for future Unmanned Traffic Management (UTM) or U-space (Geister & Korn, 2018). This concept concentrates on integrating novel airspace users, such as UAS and Urban Air Taxis, into uncontrolled, Class G airspace.…”

“…This concept concentrates on integrating novel airspace users, such as UAS and Urban Air Taxis, into uncontrolled, Class G airspace. Depending upon the individual performance parameters of aircraft, each aircraft is modeled by an ellipsoid, which is the airspace partitioned into cells of the same requirements on airspace usage (Geister & Korn, 2018). If the aircraft has an overall low performance in relation to navigation, communication, and the detecting capabilities relative to other aircraft (cooperatively and uncooperatively), it will be assigned to the larger resulting safety ellipsoid (Geister & Korn, 2018), as illustrated in Figure 1.…”

“…Since the airspace segments are reliant on their capacity on the separation requirements of the airspace users operating in that, aircraft with different specific equipment and capability may have different separation requirements and, in this way, also dynamically influence the capacity of an Figure 1. Relative separation distances considering different aircraft types (Geister & Korn, 2018).…”

This DLR Blueprint concept results in airspace management, which allows more flexibility for aircraft operating at low density but little freedom at high density due to separation requirement constraints (Geister & Korn, 2018).…”

and policing services (Reiche et al., 2019). The aviation industry needs to address the technological, physical, functional, and integrational challenges of system-of-systems depending on each other to a large degree to make UAM viable (NASA, 2018). Many of the most critical problems to UAM are the capacity of the existing air traffic management system, the accessibility of takeoff and landing areas and charging systems on the ground, regulations and certifications, adverse weather conditions, pilot shortage, and public acceptance of aircraft noise (Vascik & Hansman, 2018). These challenges could hinder implementation and limit the sustainable growth of UAM systems. To tackle these challenges, many organizations in the aviation industry, academia, and government have conducted extensive studies on the issue of UAM vehicle development and technology. The National Aeronautics and Space Administration (NASA) has carried out numerous ongoing research projects that substantially support UAM. These continuing projects include "UAS Traffic Management (UTM) & UAS Integration in the NAS (UAS-NAS), Flight Demonstrations and Capabilities (FDC), X-57, Air Traffic Management-Exploration (ATM-X), System Wide Safety (SWS), Transformative Tools & Technologies (TTT), Revolutionary Vertical Lift Technologies (RVLT), and Advanced Air Mobility (AAM)" (NASA, 2019, p. 11). UAS are currently operating at low altitudes (e.g., below 400 feet). UAS have used the Unmanned Aircraft Systems (UAS) Traffic Management (UTM) services, which provides a set of traffic management services via a federated group of UTM Service Suppliers (USS), similar to traditional Air Traffic Control (ATC) services provided to IFR and VFR aircraft (Lascara et al., 2019). According to Ghayouraneh, El-Ghazaly, and Rankin (2018), UAM operations are expected to occur above 400 feet (between 1,000-3,000 feet). Even when transitioning from higher airspace to lower airspace (below 400 feet), UAM aircraft may not be able to leverage 58

“…The size of this ellipsoid is depending on navigation, communication and the capability to detect other airspace users (cooperatively and uncooperatively). For communication parameters such as datalink latency, robustness, integrity and availability define specific parameters describing the ellipsoidal shaped bound for each aircraft [7].…”

Over the past years the UAV market has grown rapidly and will continue so. Several manufacturer offer UAVs, which differ in their size, equipment or performance. Besides the basic regulations many initiatives deal with the question of how a future airspace management system for unmanned and manned airspace users could look like. The German Aerospace Center (DLR) has started the City-ATM project [1], which seeks to identify essential components for such a system. The focal point is on a safe, secure and efficient integration of new airspace users, but also to be robust against failures. Therefore the drone operator needs on the one hand information about his drone and on the other hand information about the surrounding airspace users. In the course of City-ATM, DLR works together with several external partners to find, test and validate a variety of solutions which enable such an airspace management system as well as necessary subsystems and solutions that are needed in such a system. One of the solutions to find and validate is a redundant communication system to enable reliable data exchange between drone and pilot as well as unmanned aerial system and airspace management system. In this paper the technical setup, consisting of a (mobile) ground and air module and the basic functionality will be described to meet the requirements from a future UTM system. In addition the HyraCom system has been evaluated by conducting flight tests under real conditions and external influences in VLL (Very Low Level) airspace. In this context communication range and latency of each C2 link has been used as performance criteria.
