Abstract: With the increasing demand for urban passenger transportation, the concept urban air mobility (UAM) has gained a lot of research interest. One idea is to employ fully autonomous air crafts. That is, using unmanned and not remotely piloted aerial vehicles as a means of mass transit. Clearly, fully autonomous air taxis constitute a safety critical, time sensitive application. Efficient information management is a prominent requirement and the infrastructure for sensing and fast, reliable communication is the key to mitigate any harm in the aforesaid approach. Nevertheless, failures in such a system are inevitable and need to be addressed. This work investigates the significant aspect of building a fault-tolerant UAM communication network. We introduce a concept of distributed ground station architecture and a protocol for role delegation to improve system availability. This assures an uninterrupted service continuation fulfilling the high standards of safety requirements in an UAM system.

Abstract: The emerging implementation of urban air mobility (UAM) is in need of a robust low latency communication system. The key priority is to cope with the required high level of safety assurance. 5G communication standards lay the foundation for a promising communication infrastructure, yet there exists the challenge of connectivity and coverage through the base station network. In this paper, we address this aspect and study the realization of a reliable and efficient 5G base station plan and evaluate its influence on the performance of the UAM communication system through simulations. Our findings can assist in real UAM deployment scenarios to search for the most cost effective radio network planning solution. We focus on the 3d-channel model and on the number and placement of base stations. As a use case we consider the Hamburg metropolitan region.

Abstract: We present a modular simulation toolchain for urban air mobility (UAM), used to investigate interdisciplinary challenges in research fields like transportation planning, air-traffic research, control systems and telematics. The framework can be enhanced to evaluate the connection between travel times and demand, or the inter-dependence of U-Space regulations and self-separation performance. In an example scenario, UAM demand is based on the share of passengers using existing modes in a transportation model. Missions for urban air routes are computed on a layered grid, and conflicts are resolved in a pre-departure scheduling. The multi-agent simulation framework based on OMNeT++ integrates complex dynamics and guidance, navigation, and control algorithms, as well as different communication protocols like 5G. We evaluate a workflow for the city of Hamburg with several thousand flights, based on transportation-related key-performance-indicators.
