One of the more interesting pieces of hardware on the new Nancy Grace Roman Space Telescope (RST) is its communications antenna.
Roman and JWST both use S-band for command/telemetry/ranging and Ka-band for science data, but their antenna systems are quite different. 🧵⬇️

CCSDS invites European amateur satellite operators, students, educators, and academic researchers to participate and to help advance open, interoperable space communication technologies.
This invitation is issued with the support of ESA, in partnership with Goonhilly Earth Station, CCSDS, AMSAT-UK, and AMSAT-DL, as part of the CCSDS Outreach Initiative and Competition.
The competition focuses on open, standards-based communications, with particular interest in:
• Open-source reference implementations
• Software-defined radios and protocol stacks
• Ground and space communications experimentation
To support open-source contributors and project teams, the project partners will organise:
• 📅 Introductory Webinar: on 14th January 2026
– Technical scope, interfaces, and evaluation approach
• 🧑💻 Prototype Hackathon: March 2026 at Goonhilly Earth Station, Cornwall, UK
– A collaborative development sprint to accelerate working prototypes
Further information on the initiative and competition is available here:
