The Global UTM Association (GUTMA) is a Swiss nonprofit association that advances safe, secure, and efficient integration of uncrewed aircraft into civil airspace. Founded in Lausanne in 2016, it brings together air-navigation providers, aircraft operators and manufacturers, UTM service and infrastructure providers, regulators, and researchers from around the world. GUTMA develops interoperability blueprints, implementation guidance, service frameworks, policy positions, and readiness research; convenes its Harmonized Skies forum and member task forces; and contributes technical expertise to international standards work on uncrewed aircraft traffic management.
