  Europe de la défense : Emmanuel Macron attend de nouvelles propositions

  Par Nathalie Guibert Il a déjà remis une note d'étape à Emmanuel Macron, son rapport sera bouclé à la fin de l'année. Missionné par le président sur le sujet piégé de l'Europe de la défense, l'ancien secrétaire général pour la défense et la sécurité nationale, Louis Gautier (par ailleurs membre du conseil de surveillance du Monde), suggère des décisions fortes. Sa mission s'achèvera en février 2019 après des consultations diplomatiques pour tester les idées retenues par l'Elysée. « En parlant d'armée européenne, Emmanuel Macron permet d'incarner le projet pour nos concitoyens, de secouer la technostructure, de pousser à la clarification des choix, car le moment de vérité arrive pour les Européens », indique-t-il. Tout l'inverse des petits pas symbolisés par « l'initiative européenne d'intervention » avancée par le même Macron en septembre 2017, un concept dit « pragmatique » d'échange stratégique – hors des cadres formels dédiés de l'Union européenne –, sur lequel la ministre des armées, Florence Parly, travaille. M. Gautier considère ce projet comme un pis-aller à court terme, le résultat tangible minimum dans la période de crise politique que connaît l'Europe. « Beaucoup sont déçus par les résultats opérationnels de la défense européenne dans les administrations, aux affaires étrangères comme à la défense. Ils pensent que le militaire restera toujours du ressort national ou de l'OTAN, et que l'Europe ne servira qu'à financer les ...

  Shaken and stirred: British Army's Ajax troubles cast a long shadow

  General Dynamics' land systems operation in Spain has already built half of the hulls for the British Army's Ajax armored cavalry program, even as the future of the vehicle is threatened by noise and vibration problems.

  TNO has signed a contract with ESA to start phase 2 of TOmCAT

  July 2, 2020 - TNO has signed a contract with ESA to demonstrate cutting-edge optical communication technologies for future terabit-per-second telecom satellites. The TOmCAT project (Terabit Optical Communication Adaptive Terminal) will enable high-throughput laser communication between ground stations and satellites. This project is Phase 2 of TOmCAT, which started in 2017. It brings together key players in the Space and High-Tech industries, including: TNO, Airbus Defence & Space Netherlands, FSO Instruments (consortium partner Demcon), Hittech Multin (NL), Celestia-STS (NL), MPB Communications (CA), Airbus DS SAS (FR) and Eutelsat (FR), SES (LU). TOmCAT is a co-funded activity in which TNO, the companies involved, the Canadian Space Agency and the Netherlands Space Office invest through the ESAs ARTES Strategic Programme Line ScyLight. Key technologies include high-bandwidth adaptive optics, thermally stable opto-mechanics, high-power photonics, and high-throughput optical transceivers. TNO Space aims to enable secure broadband connectivity that will support the growing demand for data and increase communication efficiency. We also help stimulate economic growth in the Netherlands and Europe by enabling companies to realise new products, generate new business and improve their competitive position. TOmCAT is one example of these goals in practice. HOW DOES TNO CONTRIBUTE TO TOMCAT? TNO brings all parties together and integrates all expertise to: 1) Design the end-to-end Optical Feeder Link for high-throughput satellites. 2) Build and test cutting-edge technologies required for future Terabit Optical Ground Stations. 3) Build an end-to-end Optical Ground Terminal demonstrator and test it in a 10 km ground-to-ground link. This will show the technical feasibility of future terabit-per-second laser communication between ground and satellite terminals. TNO considers development in the TOmCAT project to be a major and important step towards the realisation of commercial Optical Ground Terminals and Optical Ground Stations for high-throughput Optical Feeder Links. Furthermore, TNO will work in the coming period, in parallel with TOmCAT phase 2, with Airbus Defence & Space Netherlands on business development and, in collaboration, position Airbus DS NL as future Original Equipment Manufacturer (OEMer) of these Optical Ground Terminals and Optical Ground Stations. TECHNOLOGY AND APPLICATION TOmCAT is a technology development project with the end goal of developing a commercial optical ground station product. With high-data-rate laser links, this ground station can communicate with the next generation of Very High Throughput Satellites. One of the innovative elements of TOmCAT is its ability to pre-correct the laser light with adaptive optics. When light moves between the surface of the Earth and space, it gets distorted due to the fluctuations in the atmosphere. TOmCAT measures the distortion of the received laser light from the satellite, and by applying the inverse of this distortion to the transmitted light, a robust communication link can be established. In order to enable this, high speed adaptive optics is required. An important objective for the project is to build a demonstrator to test and prove this concept.
