Founded in 2014 with offices in France and Boston, Elistair develops tethered drones and powered tethering stations for third-party drones, for defense, civil security, security companies and major industrial groups. The systems developed by Elistair allow to quickly and simply secure an area, an event, or a sensitive site, by offering a global and secure aerial view, in a continuous way. The company markets its products in more than 65 countries and has rapidly developed and structured itself to become one of the main players in the field of tethered UAVs at the international level.

Elistair's customers include the United Nations, the French Defense Agency, the UK Ministry of Defense, the US Army, the New York State Police, the Belgian Police, the Spanish Police, Vodafone, Thales and Petronas.

Elistair’s role in NESTOR project is to bring its tethered UAVs knowledge to increase the level of awareness of the global solution. Elistair will provide a tethered drone and a camera, and integrate its system to the same level of communication as the other surveillance systems.
