A European project designed to prove the feasibility of operating unmanned aerial systems in non-segregated airspace completed six missions flown form the Spanish Air Force base San Javier air base on 24 April. Defense-Update reports.
The test was conducted by an international consortium led by Spain’s Indra, in cooperation with AT-One, CIRA, SES ASTRA and Thales Alenia Space. The project demonstrated the safe operation of RPAS in non-segregated airspace using satellite communications.
The test involved a satellite communications link using Ku-band capacity, provided SES Techcom. The link established immediately after take-off, while the aircraft was still in segregated airspace, before it entered class-C airspace at 20,000ft under the supervision of Spanish air navigation service provider Aena. The sat-link provided reliable command and control, Air Traffic Control and Mission data transfer.
During the trial, a manned aircraft from the Spanish air force academy approached the UAS, simulating frontal and 90˚ collision trajectories. “The pilots of the two aircraft followed the separation instructions issued by the air traffic controllers, demonstrating the safe operation of remotely-piloted aircraft, even in an emergency situation,” the EDA, ESA and Indra said in a joint statement.
The missions flown under the European Space Agency – European Defense Agency (ESA-EDA) sponsored ‘Demonstrating Satellites enabling the Insertion of RPAS in Europe’ (DeSIRE) initiative. Other members collaborating in the program included ThalesAleniaSpace and AT-one (an European Economic Interest Group consisting of Dutch Aerospace Laboratory NLR and German Aerospace Centre DLR). Other partners, included GUCI (Spanish “Guardia Civil”) and AENA (Aeropuertos Españoles y Navegación Aérea).
The initiative followed another ESA study (ESA SINUE) during which SES was already partnering with INDRA, the Spanish information technology and defense systems company.
SES operates a fleet of 52 geostationary satellites. The company provides satellite communications services to broadcasters, content and internet service providers, mobile and fixed network operators and business and governmental organisations worldwide.
