On 3 November 2025, InterUSS stakeholders from across the globe convened in Zurich, Switzerland, for the InterUSS Technical Workshop & Interoperability Roundtable.
Assessing the impact of the workshop
The event brought together 30 participants among CAAs (Civil Aviation Authorities), USSPs (U-space Service Providers), and industry innovators to examine how open-source tools and automated testing frameworks could accelerate compliance, interoperability, and trust in emerging airspace systems.
Discussions underscored a shared commitment to transparency and collaboration, core values of the InterUSS Platform, and participants were introduced to Skypuzzler, the newest member addition to InterUSS: a deep-tech company founded in 2022 that specializes in advanced strategies for tactical real-time deconfliction.
Swiss use case and live InterUSS interoperability demo
The first session, presented by Amanda Boekholt, Head of Technology and Innovation at the Swiss Federal Office of Civil Aviation (FOCA), and Michael Barroco, Member of the InterUSS Technical Committee, spotlighted the Zurich U-space implementation field test (V1).
The Swiss use case revealed how leveraging proven best practices and shared resources can ensure significant time savings and improve operational efficiency. Moreover, it highlighted the importance of better developing USSP-to-USSP interoperability using the Discovery and Synchronization Service (DSS).
According to FOCA, automated onboarding and compliance testing for USSPs, aligned with Service Description Documents (SDDs), played a critical role in streamlining processes, while a structured three-gate onboarding approach ensured readiness at every stage, from self-validation to production flights.
The demonstration proved how Automated Testing reduced complexity, accelerated integration, and built confidence in multi-provider ecosystems. This perspective was reinforced by the FAA during the U.S. UTM implementation, where InterUSS products were acknowledged as meeting critical operational needs and supporting interoperability.
Australian deployment case study
Will Whitelaw from the Australian Civil Aviation Authority (CASA) presented Australia’s experience in adopting InterUSS Automated Testing for regulatory oversight.
CASA’s experience revealed dramatic time savings, with compliance checks dropping from five hours to just five minutes, enabling fair competition for both small and large providers and presenting a more equal competition scenario for the industry. This case study illustrated how RegTech (Regulatory Technology) and automation are crucial for the transformation of regulatory assurance, dynamic data integration, and global harmonization of testing methodologies.
Interactive roundtable
During the interactive roundtable, both speakers and participants shared their perspectives on how regulators can build trust and implement innovation for oversight in the low-altitude economy, what operators are learning from real-world deployments, and how open tools like InterUSS can support scalability.
The participants reaffirmed InterUSS’s ultimate goal: strong collaborations to support open-source solutions that enable fairer and more transparent UTM ecosystems.
Looking ahead
A clear takeaway from the workshop was that automation is a new way of doing oversight. Participants explored how real-world applications of InterUSS products are building confidence and delivering tangible results. These successes, combined with the continuous evolution of supported services, are laying the foundation for more efficient and scalable UTM ecosystems. Positive outcomes are driving growing trust across the industry as we continue to learn by doing, actively involving the entire ecosystem through feedback and collaborative discussions.
