[QUOTE="elkahn, post: 2775130, member: 33892"] Bueno, habría que avisarle al DoD que se está equivocando con la arquitectura satelital que desarrolla para sus fuerzas y las bandas que elije: Wideband Global SATCOM The Wideband Global SATCOM system (WGS) is a high capacity satellite communications system planned for use in partnership by the United States Department of Defense (DoD), Canadian Department of National Defence (DND) and the Australian Department of Defence [URL]https://en.wikipedia.org/wiki/Wideband_Global_SATCOM#Block_II_Follow-On[/URL] Lo mismo en Europa… GovSat-1 to deliver secure communications for governments The Military Ka-band will be used predominantly for mobility applications in support of Intelligence Surveillance and Reconnaissance (ISR) missions. The secure communication links it enables are characterized by smaller high-throughput VSAT terminals. The Mediterranean Sea is one particular area covered by a high-power beam in military Ka-band. It is therefore ideally suited to enable communications for European Border Surveillance applications.

Todd Smith, the U.S. Army deputy project manager for PEO Aviation's Unmanned Aircraft Systems Project Office in Huntsville, Ala., said that initial operational capability for Ka-band enabled Gray Eagles will be in 2022. The full fleet is to scheduled to have Ka-band capability by 2027. The military has 10 wideband global satcom (WGS) satellites for the provision of real-time data and video to and from deployed forces and commanders, often in long-range and long-endurance operations. The Gray Eagle "[B]switch to Ka band datalink allows the fielded units to utilize the WGS system with its high bandwidth capability, and its greater security, reliability and availability[/B] than currently used satellite communications systems," said an Army official.

Space Force unveils vision for integrated SATCOM architecture Centralized management and interoperability, achieved in part via flexible user terminals, are among the keys to delivering satellite communications (SATCOM) capabilities efficiently and reliably to U.S. warfighters using a combination of commercial and government-owned satellite systems, according to the newly created U.S. Space Force. [URL]https://ses-gs.com/govsat/defense-intelligence/space-force-unveils-vision-for-integrated-satcom-architecture/[/URL] No, no es solo en banda X. Realmente no sé si el Arsat SG1 finalmente tendrá aplicaciones para la defensa, pero ni su capacidad de encriptación ni la banda parecen ser obstáculos insalvables. Por mi parte mantengo la expectativa que así sea. Disculpas por el idioma de los textos, no encontré en castellano. Ingresando a los links, con el traductor se puede zafar. Saludos!! [/QUOTE]
