Airbus va développer la constellation d'observation de la Terre CO3D du CNES
Avec AFP
Airbus Defense and Space et le CNES, l'agence spatiale française, ont annoncé lundi avoir signé un contrat pour développer une constellation de quatre satellites d'observation de la Terre en 3D, à vocation civile et militaire.
La constellation CO3D (Constellation optique en 3D) sera composée de quatre satellites électriques de 300 kilos chacun environ qui seront lancés en 2022.
Elle "permettra de fournir des images stéréoscopiques (image prise par deux capteurs légèrement distants, NDLR) de résolution submétrique (50 cm), à vocation mondiale", précient le CNES et Airbus Defense and Space dans un communiqué commun.
Avec les quatre satellites Pléiades Neo qui seront lancés à partir de 2020, voire avec les deux Pléiades lancés en 2011 et 2012 s'ils fonctionnent encore, "la constellation CO3D offrira une capacité de revisite inégalée pour l'imagerie à haute résolution", affirment-ils.
En orbite héliosynchrone, à environ 800 km d'altitude, cette flotte de satellites permettra en effet de repasser plus fréquemment au-dessus d'un point donné pour voir l'évolution de la situation.
Le budget est d'environ 200 millions d'euros, réparti pour moitié entre le CNES et Airbus, selon une source proche du dossier.
Airbus Defense and Space, qui sera chargé de la construction et de la gestion des satellites, l'a emporté sur Thales Alenia Space. L'entreprise fournira notamment un "Modèle numérique de surfaces (MNS) global de haute précision" qui permet la modélisation 3D de carte ainsi que les images à "l'utilisateur final qui est le gouvernement français", à travers le CNES, selon Airbus Defense and Space.
L'agence spatiale, pour qui c'est un projet dual, civil et militaire, s'en servira pour la gestion des risques naturels, la recherche scientifique ou encore pour les besoins des armées.
"C'est une gouvernance très originale, un partenariat entre le public et le privé, un coinvestissement équilibré qui permet d'associer des besoins publics et des besoins commerciaux. Le CNES n'est pas propriétaire de l'infrastructure, ce qui est une première", a-t-on souligné à l'agence spatiale.
"Ce contrat conforte Airbus en tant que partenaire de confiance pour le CNES et les autorités françaises et renforce notre position de leader du marché en Europe et dans le monde", se félicite le président d'Airbus Defense and Space France, cité dans le communiqué.
Pour le président du CNES Jean-Yves Le Gall, également cité dans le communiqué, la constellation CO3D ouvre "une nouvelle ère dans l'observation de la Terre", permettant "notamment un plus haut débit de réactualisation, une plus grande résilience ainsi que des performances élevées".

Pentagon clears 100 MHz of spectrum for 5G development
Nathan Strout The Pentagon has cleared 100 megahertz (MHz) of contiguous mid-band spectrum to be used for commercial 5G following a 15-week review, determining that they can share that bandwidth while minimizing impact on military radars. While that 3450-3550 MHz mid-band spectrum is highly desired by commercial 5G developers, it's been historically used by the military for critical radar operations for air defense, missile and gunfire control, counter-mortar, bomb scoring, battlefield weapon locations, air traffic control, and range safety. But now, leaders from the Department of Defense say the Pentagon can continue using the spectrum for those purposes while making it available for commercial development. DoD Chief Information Officer Dana Deasy said the department will move toward sharing most of that spectrum without limits while setting up a Spectrum Relocation Fund Transition Plan to minimize risks. “DoD is proud of the success of the [America's Mid-Band Initiative Teams (AMBIT)] and is committed to working closely with industry after the FCC auction to ensure timely access to the band while protecting national security,” Deasy told reporters Aug. 10. The White House and Department of Defense established AMBIT to free up spectrum for 5G development quickly back in April. Over a 15-week period, the working group was able to bring together 180 subject matter experts, and ultimately were able to identify 100 MHZ of spectrum used by the military that could be safely shared with commercial 5G efforts.The decision expands the amount of connected mid-band spectrum open for 5G development to 530 MHz. The Federal Communications Commission will auction off the spectrum. One government official said action was expected by the end of this fiscal year. https://www.c4isrnet.com/industry/2020/08/10/pentagon-clears-100-mhz-of-spectrum-for-5g-development/

Amentum to acquire DynCorp International
Joe Gould WASHINGTON ― An affiliate of government contractor Amentum will buy DynCorp International, the global services provider, the companies announced Thursday. The deal, for undisclosed terms, is expected to close in the fourth quarter of this year. In a joint release, the companies billed the deal as creating a mission-critical support services powerhouse, as they have had, collectively, $6 billion in revenue over the last 12 months. The new entity would employ 34,000 people in more than 30 countries. “The combination of our two companies will accelerate our growth into key new markets such as aviation support services, contractor logistics support, intelligence solutions, and training,” said Amentum CEO John Vollmer. Earlier this year, Amentum launched as a privately held company after the sale of the AECOM Management Services business to affiliates of Lindsay Goldberg and American Securities LLC. The new firm provides mission support and equipment sustainment, information technology, intelligence, nuclear and environmental remediation, among other services. “We look forward to welcoming DynCorp's employees to the Amentum family," Vollmer said. "Our complementary capabilities and cultures will propel Amentum to the top of our market as a leader with differentiated solutions to support our clients' most challenging missions.” In April, DynCorp won a $185 million, nine-month extension to support Army Sustainment Command in Southern Afghanistan under the Logistics Civil Augmentation Program (LOGCAP) IV contract. The company said it has continuously provided LOGCAP services for the U.S. Army for 11 years. “This strategic combination of two market leading companies will deliver tremendous value to our customers and increased opportunities for our employees,” said DynCorp CEO George Krivo. https://www.defensenews.com/congress/2020/09/25/amentum-to-acquire-dyncorp-international/
