JARUS stands for 'Joint Authorities for Rulemaking on Unmanned Systems.' It is a coalition of national aviation authorities aimed at developing rules and recommendations for the operation of Unmanned Aircraft Systems (UAS) or drones. The organization promotes the harmonization of regulations for UAS on an international level to facilitate the integration of these systems into airspace and ensure consistent safety standards. JARUS works closely with the International Civil Aviation Organization (ICAO) and provides a platform for the exchange of information and best practices among various national regulatory authorities.
