    Thales Alenia Space wins two contracts from ESA to study future upgrades to Europe’s EGNOS Navigation System

    Cannes, May 18, 2020 – The European Space Agency (ESA) has awarded two contracts to Thales Alenia Space, the joint company between Thales (67%) and Leonardo (33%), concerning EGNOS (European Geostationary Navigation Overlay Service). These contracts, fully financed under the European Commission H2020 programme concern study phases on the system evolution. They will call on Thales Alenia Space's expertise as program prime contractor for over 25 years to study and develop upgrades for the EGNOS satellite navigation system. The first contract concerns possible upgrades for EGNOS aeronautical services, designed to improve performances in order to increase landing safety under limited visibility conditions (from current CAT-I to CAT-II), over the current EGNOS footprint, focused on Europe. The second contract will study changes required to extend its aeronautical services worldwide. Based on state-of-the-art technologies, this upgrade will call on the A-RAIM (Advanced Receiver Autonomous Integrity Monitoring) concept and the global coverage of the Galileo satnav constellation. RAIM is an already deployed technology that assesses the integrity of signals in the receivers that are part of a global positioning system, mainly GPS. Galileo will now be incorporated in the advanced version of this concept, A-RAIM, to provide enhanced horizontal guidance performance, not possible with RAIM using only GPS. The new concept would thus provide “safety of life” aeronautical services, including approaches with vertical guidance, thanks to inputs from GPS and Galileo via EGNOS. “Today's contracts are key for satellite navigation in Europe and bolster Thales Alenia Space's European leadership in state of art satellite navigation systems, including Safety of Life services”, said Benoit Broudy, head of the Navigation business at Thales Alenia Space in France. He added: “Our successes on export markets, as in South Korea, validate our innovative approach that allows us to offer increasingly powerful and agile solutions to meet the evolving requirements of customers from around the world.” About EGNOS EGNOS, a European Union flagship program, is a satellite navigation system designed to improve positioning signals delivered by GPS. Developed by Thales Alenia Space as prime contractor, EGNOS was first deployed in 2005, began operating in open service mode in 2009 and provided Safety of Life service starting in 2011. The GNSS R&D activities are financed by the European Commission H2020 programme. They are managed by the European Space Agency through a delegation agreement from the European Commission. Safety of Life service, a success in export markets The EGNOS Safety of Life service is used to carry out precision airport approaches, especially landings, without requiring ground guidance systems. Building on its expertise in this field, Thales Alenia Space won a contract in 2016 from the Korean space agency to supply the Korean Augmentation Satellite System (KASS). With its Safety of Life capability, KASS is a regional Korean navigation system that will initially be used for aviation. It will provide critical services at several points of each flight, especially landing, so that, airports no longer need ground landing aid facilities. Along the same lines, in early 2019 ASECNA, the air navigation safety agency for Africa and Madagascar, chose Thales Alenia Space to handle a Phase B project that will include the supply of a pre-operational service in 2020 for a Satellite Based Augmentation System (SBAS) in sub-Saharan Africa, to provide an optimized satellite-based solution to support the growing air traffic in this region. The project recently took a major step forward, with validation of the system's architecture and main performance characteristics. This study is being carried out jointly by ASECNA and Thales Alenia Space, with funding from the European Union, as part of an ambitious program to develop the aviation sector in Africa. Set for completion by the end of the year, it also includes the supply of a pre-operational service, along with demonstrations of how to use the service in conjunction with partner airlines. Thales Alenia Space has now completed acceptance testing of the demonstrator, which will subsequently be deployed at various sites. ABOUT THALES ALENIA SPACE Drawing on over 40 years of experience and a unique combination of skills, expertise and cultures, Thales Alenia Space delivers cost-effective solutions for telecommunications, navigation, Earth observation, environmental management, exploration, science and orbital infrastructures. Governments and private industry alike count on Thales Alenia Space to design satellite-based systems that provide anytime, anywhere connections and positioning, monitor our planet, enhance management of its resources, and explore our Solar System and beyond. Thales Alenia Space sees space as a new horizon, helping to build a better, more sustainable life on Earth. A joint venture between Thales (67%) and Leonardo (33%), Thales Alenia Space also teams up with Telespazio to form the parent companies' Space Alliance, which offers a complete range of services. Thales Alenia Space posted consolidated revenues of approximately 2.15 billion euros in 2019 and has around 7,700 employees in nine countries. www.thalesaleniaspace.com THALES ALENIA SPACE – PRESS CONTACTS Sandrine Bielecki Tel: +33 (0)4 92 92 70 94 sandrine.bielecki@thalesaleniaspace.com Catherine des Arcis Tel: +33 (0)4 92 92 72 82 catherine.desarcis@thalesaleniaspace.com Marija Kovac Tel: +39 (0)6 415 126 85 marija.kovacsomministrato@thalesaleniaspace.com View source version on Thales: https://www.thalesgroup.com/en/worldwide/space/press-release/thales-alenia-space-wins-two-contracts-esa-study-future-upgrades

    Artificial intelligence expert gets top job at French defense innovation agency

    By: Pierre Tran PARIS — French Armed Forces Minister Florence Parly has appointed Emmanuel Chiva, a specialist in artificial intelligence and training simulation, as director of the newly formed agency for defense innovation, the ministry said. Chiva took up the post Sept. 1, when the innovation office was officially set up, the ministry said in a Sept. 4 statement. Parly made the appointment in consultation with Joël Barre, head of the Direction Générale de l'Armement procurement office. The innovation agency will report to the DGA. The agency will be the key player in a new strategy for innovation, seeking “to bring together all the actors in the ministry and all the programs which contribute to innovation in defense,” Parly said in an Aug. 28 speech to a conference held by Medef, an employers' association. The innovation office will be open to Europe, while allowing experiments to stay close to their operational users, she said. Parly has set a budget of €1 billion (U.S. $1.2 billion) for the agency, which will seek to coordinate attempts to apply new technology to military applications. Chiva has more than 20 years of experience in AI and training simulation. He previously held a senior post for strategy and development at Agueris, a specialist in training simulation for land weapon systems. Agueris is a unit of CMI Defence, a Belgian company specializing in guns and turrets for armored vehicles. Agueris was on the CMI stand at the Eurosatory trade show for land weapons in June. Agueris held three conferences on AI, with Chiva speaking at a roundtable debate on innovation. Chiva is a graduate of Ecole Normal Supérieure and a specialist in biomathematics, the study of the application of math to biology. “His appointment perfectly illustrates my vision of defense innovation: open to research and the civil economy, in which entrepreneurship is not a concept but a reality,” Parly said. https://www.defensenews.com/industry/techwatch/2018/09/05/artificial-intelligence-expert-gets-top-job-at-french-defense-innovation-agency

  • In a future USAF bomber force, old and ugly beats new and snazzy

    In a future USAF bomber force, old and ugly beats new and snazzy

    Robert Burns, The Associated Press WHITEMAN AIR FORCE BASE, Mo. — In the topsy-turvy world of U.S. strategic bombers, older and uglier sometimes beats newer and snazzier. As the Air Force charts a bomber future in line with the Pentagon's new focus on potential war with China or Russia, the youngest and flashiest — the stealthy B-2, costing a hair-raising $2 billion each — is to be retired first. The oldest and stodgiest — the Vietnam-era B-52 — will go last. It could still be flying when it is 100 years old. This might seem to defy logic, but the elite group of men and women who have flown the bat-winged B-2 Spirit accept the reasons for phasing it out when a next-generation bomber comes on line. “In my mind, it actually does make sense to have the B-2 as an eventual retirement candidate,” says John Avery, who flew the B-2 for 14 years from Whiteman Air Force Base in western Missouri. He and his wife, Jennifer, were the first married couple to serve as B-2 pilots; she was the first woman to fly it in combat. The Air Force sees it as a matter of money, numbers and strategy. The Air Force expects to spend at least $55 billion to field an all-new, nuclear-capable bomber for the future, the B-21 Raider, at the same time the Pentagon will be spending hundreds of billions of dollars to replace all of the other major elements of the nation's nuclear weapons arsenal. The Air Force also is spending heavily on new fighters and refueling aircraft, and like the rest of the military it foresees tighter defense budgets ahead. The B-2′s viability suffers from the fact that only 21 were built, of which 20 remain. That leaves little slack in the supply chain for unique spare parts. It is thus comparatively expensive to maintain and to fly. It also is seen as increasingly vulnerable against air defenses of emerging war threats like China. Then there is the fact that the B-52, which entered service in the mid-1950s and is known to crews as the Big Ugly Fat Fellow, keeps finding ways to stay relevant. It is equipped to drop or launch the widest array of weapons in the entire Air Force inventory. The plane is so valuable that the Air Force twice in recent years has brought a B-52 back from the grave — taking long-retired planes from a desert “boneyard” in Arizona and restoring them to active service. Strategic bombers have a storied place in U.S. military history, from the early days of the former Strategic Air Command when the only way America and the former Soviet Union could launch nuclear weapons at each other was by air, to the B-52′s carpet bombing missions in Vietnam. Developed in secrecy in the 1980s, the B-2 was rolled out as a revolutionary weapon — the first long-range bomber built with stealth, or radar-evading, technology designed to defeat the best Soviet air defenses. By the time the first B-2 was delivered to the Air Force in 1993, however, the Soviet Union had disintegrated and the Cold War had ended. The plane made its combat debut in the 1999 Kosovo war. It flew a limited number of combat sorties over Iraq and Afghanistan and has launched only five combat sorties since 2011, all in Libya. The last was a 2017 strike notable for the fact that it pitted the world's most expensive and exotic bomber against a flimsy camp of Islamic State group militants. “It has proved its worth in the fight, over time,” says Col. Jeffrey Schreiner, who has flown the B-2 for 19 years and is commander of the 509th Bomb Wing at Whiteman, which flies and maintains the full fleet. But after two decades of fighting small wars and insurgencies, the Pentagon is shifting its main focus to what it calls “great power competition” with a rising China and a resurgent Russia, in an era of stiffer air defenses that expose B-2 vulnerabilities. Thus the Pentagon's commitment to the bomber of the future — the B-21 Raider. The Air Force has committed to buying at least 100 of them. The plane is being developed in secrecy to be a do-it-all strategic bomber. A prototype is being built now, but the first flight is not considered likely before 2022. Bombers are legend, but their results are sometimes regretted. A B-2 bomber scarred U.S.-China relations in 1999 when it bombed Beijing's embassy in the Serbian capital of Belgrade, killing three people. China denounced the attack as a “barbaric act,” while the U.S. insisted it was a grievous error. The Air Force had planned to keep its B-2s flying until 2058 but will instead retire them as the B-21 Raider arrives in this decade. Also retiring early will be the B-1B Lancer, which is the only one of the three bomber types that is no longer nuclear-capable. The Air Force proposes to eliminate 17 of its 62 Lancers in the coming year. The B-52, however, will fly on. It is so old that it made a mark on American pop culture more than half a century ago. It lent its name to a 1960s beehive hairstyle that resembled the plane's nosecone, and the plane featured prominently in Stanley Kubrick's 1964 black comedy, “Dr. Strangelove.” More than once, the B-52 seemed destined to go out of style. “We're talking about a plane that ceased production in 1962 based on a design that was formulated in the late 1940s,” says Loren Thompson, a defense analyst at the Lexington Institute, a Washington think-tank. Rather than retire it, the Air Force is planning to equip the Boeing behemoth with new engines, new radar technology and other upgrades to keep it flying into the 2050s. It will be a “stand off” platform from which to launch cruise missiles and other weapons from beyond the reach of hostile air defenses. In Thompson's view, the Air Force is making a simple calculation: The B-52 costs far less to operate and maintain than the newer but finickier B-2. “They decided the B-52 was good enough,” he says. https://www.airforcetimes.com/news/your-air-force/2020/07/26/in-a-future-usaf-bomber-force-old-and-ugly-beats-new-and-snazzy/
