Proposal of a U-space Service for Tactical Conflict Prediction in a Multi-USSP Environment

This paper develops the concept of a U-space tactical conflict prediction service in a multi-provider environment. This new service, aligned with the CORUS CONOPS Ed. 4.0 and inspired by the architecture of the Discovery and Synchronization Service set out in the ASTM F3411-2022a standard, allows the exchange of telemetry between U-space service providers through a centralized system that periodically updates the positions of the unmanned vehicles. Furthermore, this document assesses the implementation of the new service by integrating concepts adopted from the BUBBLES project for tactical conflict detection, with initial proposals for data structures, databases, and system interoperability requirements. Lastly, simulations using real flight telemetries during the BUBBLES project were conducted to evaluate the results. More precisely, the number of conflicts detected and the detection time were computed and compared with those obtained in a simulated single-provider environment by the BUBBLES project.
