RAXUS · Risk-based Authorisation and eXecution in U-space airSpaces

RAXUS delivers digital solutions to streamline UAS operations in and outside U-space by automating flight authorizations and integrating risk assessment frameworks aligned with SORA and ARA standards. It enables a near-automated workflow from initial intent declaration to U-plan submission, supported by comprehensive, quantifiable risk assessments using live data on connectivity, population density, and weather. This ensures standardized, digital evidence for regulatory approval, consistent with initiatives like EASA’s e-SORA. Beyond safety, RAXUS extends the assessment framework to broader risk domains relevant to Innovative Air Mobility (IAM), including societal acceptance, visual impact, and noise.Complementing this, RAXUS introduces a second major innovation focused on the U-space flight plan authorization process itself. Today, flight approvals follow a rigid first-in-first-out (FIFO) logic that can limit efficiency and fairness in congested environments. RAXUS replaces this with a fairness-based prioritization system and a multi-stage authorization approach. Flight clearances are granted progressively, segment by segment, closer to take-off and during execution, ensuring more efficient use of airspace while adapting to real conditions such as weather, CNS performance, or mission type. This solution empowers authorities and USSPs to manage demand-capacity imbalances equitably, balancing competing operations and guaranteeing transparent access to U-space.Designed for rapid deployment within the current regulatory framework, RAXUS targets the first U-space airspaces being defined in Europe, focusing on relevant airspace classes and mission categories. Its core goal is to simplify and accelerate approvals for Competent Authorities, UAS operators, USSPs, CISPs, and regulators, enabling efficient, scalable, and safe U-space operations without structural overhauls.
