    Hello Dick


    We have a thread already:


    Die Uni Würzburg twittert (oder twiXXert :) ) den Status von SONATE-2. Blöderweise ist das Konto nicht public. Wer also wie ich kein X-Konto hat oder extra eröffnen will, kann die Stati wie folgt googeln: "JMUSpace Twitter". Ob es auch mit anderen Suchmaschinen funktioniert, habe ich nicht ausprobiert. Jedenfalls hätte ich so frühzeitig erfahren, dass letztes Wochenende SSTV aktiviert wurde.


    Einen anderen Weg bietet SatNOGS: https://network.satnogs.org/observations/?norad=98959

    aktueller geht nicht ;)

    Habe mir 2 .ogg Dateien runtergeladen und wollte mir die CW-Bake anhören. Die Lautstärke ist viel zu leise, man hört nur sehr leises Rauschen und die Bake kann man nur erahnen. Ich glaube sie gehört zu haben :(

    AO-73 Goes on Hiatus

    A messages from the FC1 operations team reads,

    “After a good period of transponder activity FUNcube batteries need a short rest. We plan to switch the transponder OFF between March 3rd to 15th subject to operational conditions. The satellite will be placed Safe mode and will still provide low power telemetry

    ESA Satellite Communications Group Explores Future Amateur Satellite Payload

    Frank Zeppenfeldt, PDØAP, representing the European Space Agency (ESA), provided key insights during a presentation on February 4th at the FOSDEM 2024 conference held in Brussels, Belgium. The discussion centered around ESA's initiative to collaborate with the amateur satellite community in defining a prospective payload for Medium Earth Orbit (MEO) or Geostationary Orbit (GEO). The ESA's involvement aims to build upon the success of the QO-100 payload in geostationary orbit, fostering innovation and technological advancements.


    During the FOSDEM conference, the ESA Satellite Communications Group outlined preliminary ideas, stressing the significance of engaging with the Software-Defined Radio (SDR) community. The primary objectives include consolidating requirements, exploring diverse payload options, addressing user segments, and thoroughly examining financing, procurement, and operational scenarios for a potential MEO/GEO amateur payload.


    The project's scope encompasses the consideration of various payload options and trade-offs, encompassing aspects such as frequency bands, analog or digital transmission, on-board SDR/Linux/GPU-box configurations, potential applications, technical risks, inter-satellite links, geographical coverage, degree of centralization, and educational components.

    To ensure a comprehensive and well-informed approach, the ESA plans to actively involve the amateur community. This engagement seeks to gather valuable input on lessons learned from the QO-100 experience, amateur requirements and interests, as well as suggestions for payload options. The consultation process extends to reaching out to AMSAT and other relevant groups, alongside dialogues with satellite operators, primes, and various stakeholders.


    Looking ahead, the ESA has outlined a timeline for the project. In March 2024, the agency intends to solicit input from the amateur satellite community and other stakeholders, guided by valuable insights from the AMSAT community. By May 2024, detailed payload options will be presented for discussion at the European Space Research and Technology Centre (ESTEC) in the Netherlands, with the support of technical expertise.


    More information from this presentation including the ten page Slide Deck can be found https://fosdem.org/2024/schedu…ollow-up-qo-100-payload-/.


    The culmination of this extensive process is expected in September 2024 at the World Satellite Business Week, where dedicated discussions with satellite operators will be organized. The ESA envisions proposing a selection of payload options at a subsequent FOSDEM conference in 2025, further demonstrating the collaborative commitment of ESA and the amateur satellite community to propel advancements in satellite communications and explore innovative possibilities for future amateur satellite payloads in both GEO and MEO orbits.
