  • Alphasat hosted payload programme to be extended

    20 December 2016 — ESA, Inmarsat, and payload providers have agreed to continue the very successful Alphasat hosted payload programme for another three years.

  • New heat dissipater keeps satellites cool in space

    13 July 2016 – With support from ESA, a European consortium led by Airbus DS has developed a novel Deployable Panel Radiator that will provide much-needed additional radiating capacity for highly dissipative payloads, such as those planned for the next generation of very high throughput satellites.

  • Sentinel-1A—Alphasat laser link delivers excellent stability and robustness

    5 August 2015 – Having recently completed 100 communication sessions, the optical inter-satellite link between Sentinel-1A  and Alphasat is delivering excellent stability and robustness under various conditions, and represents a global first.

  • Inmarsat transfers BGAN services to Alphasat

    27 March 2015 – UK satcoms operator Inmarsat has transferred its Broadband Global Area Network services to Alphasat, the advanced telecommunications satellite developed in a partnership between Inmarsat and ESA.

  • First commercial airline for Alphasat air safety service

    News: satellite-based air traffic management is now a step closer

    Hawaiian Airlines (USA) has announced it will be the first commercial airline installing Inmarsat’s (UK) SwiftBroadband-Safety, a new air safety service for trans-oceanic flights that has been designed and developed through the Alphasat Private Public Partnership between Inmarsat and ESA.

  • Alphasat

    The primary objective of ESA under the Alphasat Programme is to facilitate an early first flight, and in-orbit validation of the Alphabus platform, currently under development with industry.

  • Alphabus: An Extended European Capability

    With the Alphabus product line, European Industry extends its telecommunication satellite range significantly beyond the capabilities of the existing platforms, such as Eurostar 3000 and Spacebus 4000, both with respect to maximum payload power and mass. This development has been initiated, by ESA and CNES, as a coordinated European response to the increased market demand for larger telecommunication payloads for new broadband, broadcasting and mobile communications services.

  • Advanced laser technology on the way to space

    It´s not only superheroes from long ago in a galaxy far, far away who can harness the power of lasers. Thanks to human ingenuity and European industry, advanced laser technology providing ultra-fast and highly secure data relay will start operation in space next year.

  • Alphabus equipment phase C/D selection

    Alphabus is the industrial programme for the development of a generic line of large platforms. Alcatel Space and EADS Astrium are cooperating to develop and market Alphabus with the objective to compete successfully on the global commercial satcom market. The objective of the phase C/D programme is to establish the Alphabus product line and to procure its first flight model.

  • European Third Pillar for Satellite Telecommunications

    The Final report and the Executive Summary "European Third Pillar for Satellite Telecommunications" are the result of the JADES study (Joint Alphasat Definition Study) performed jointly by Astrium, Alcatel and Alenia for the European Space Agency.
