Airbus crée un dispositif de surveillance du trafic aérien pour les... drones
Par Alexandre Boero
La division Airbus Defence and Space a collaboré pour mettre au point Drone-it!, un dispositif de surveillance des drones, de plus en plus présents dans l'espace aérien.
Aviation, sécurité, cinéma, télévision, maintenance, surveillance : les domaines dans lesquels on les utilise à tout-va ne manquent pas. Voilà pourquoi Airbus a décidé de se concentrer sur le développement d'un appareil, via sa branche Airbus Defence and Space, qui viendra diminuer le risque de collision de drones dans le ciel.
Une technologie qui rend les drones visibles sur un radar
Souvent délicats à détecter sur radar dans un espace aérien toujours plus massif, les drones peuvent causer des situations de danger, pour les autres et pour eux-mêmes. La technologie Drone-it! vise à résoudre ce problème et permet un suivi en temps réel des drones.
Pour cela, l'appareil Drone-it! est équipé d'un récepteur et d'un émetteur GNSS (Global Navigation Satellite System ou Système mondial mondial de navigation par satellite), ainsi que d'un chipset, un jeu de puces qui rend les drones bien visibles sur un radar spécifiquement développé. Le jeu de puces possède la capacité de communiquer directement avec les réseaux au sol ou alors être relayé par satellite à orbite géostationnaire.
Des essais menés avec succès
Avec 40 vols et six scénarios différents, la technologie a été testée avec succès lors de démonstrations menées au Royaume-Uni en octobre 2018. Sous le nom de code « Class », ce projet a été mené par Airbus Defence and Space en étroite collaboration avec l'École nationale de l'Aviation civile (ENAC), l'Université norvégienne des sciences et technologies (NTU) et Unify, une filiale du géant français Atos, spécialisée dans les communications unifiées.

Lockheed Martin’s New Contract With DARPA Can Disrupt The Future Of Space
Sunnyvale, Calif – Apr. 27, 2020 – DARPA has awarded Lockheed Martin (NYSE: LMT) a $5.8 million contract for the first phase of satellite integration on the Blackjack program. Lockheed Martin will define and manage interfaces between Blackjack's bus, payload and Pit Boss - its autonomous, space-based command and data processor. Additional scope includes testbed validation of internal and external vehicle interfaces. Program work will primarily be performed in Sunnyvale, California. “Lockheed Martin has built and integrated a variety of payload types and sizes for every type of mission and we bring all of that experience to the Blackjack program,” said Sarah Reeves, vice president of Missile Defense Programs at Lockheed Martin. “This is an exciting new approach to plug-n-play design for LEO and we are up for the challenge.” DARPA's Blackjack program aims to develop and demonstrate the critical elements for a global high-speed network in low earth orbit (LEO) that provides the Department of Defense with highly connected, autonomous, resilient, and persistent coverage employing multiple payload types and missions. Future phases of Blackjack are expected to include build, test, and launch of a demonstration constellation in 2021-2022.

Eutelsat, Maxar Selected for NASA Study
By Annamarie Nyirady Maxar Technologies and Eutelsat were selected to participate in NASA's Space Relay Partnership and Services Study. This studies future systems that could revolutionize NASA's space-based communications architecture through innovative technologies and commercial partnerships. The future architecture would be used for scientific and human exploration missions in Earth orbit, at the Moon, and throughout the solar system beginning in the mid-2020s. NASA's Space Communications and Navigation Program currently offers space-based radio frequency communications services for all of the agency's space communications activities via its Space Network. The Space Network consists of a constellation of geosynchronous satellites called TDRS and ground systems that operate as a relay system between satellites. Leveraging current and planned commercial communication and navigation infrastructure, Maxar will study concepts to augment the Space Network with more advanced optical communications capabilities and enhanced radio frequency services. Maxar will also study a framework that allows for a transition from government-owned and managed space services to commercially developed and operated services. This future architecture could unlock the promise of human exploration, new and greater scientific discovery, and reduce development and operations costs for future missions through improved communication and navigation services. More specifically, Eutelsat was selected for NASA's Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2) as part of the NASA Space Relay Partnership and Services Study. The NextSTEP-2 program seeks to establish partnerships with U.S. companies to evaluate the incorporation of commercial elements into the future space relay services that will be provided by the agency's Space Communications and Navigation (SCaN) Networks. https://www.satellitetoday.com/government-military/2019/05/16/eutelsat-maxar-selected-for-nasa-study/
