Save the Date for the 42nd International Communications
Satellite Systems Conference (ICSSC)
September 23 – 25, 2025 | Barcelona, Spain

This year’s conference will be held in beautiful Barcelona, Spain from September 23rd – 25th, 2025, at the magnificent UNESCO campus, Universitat Autònoma de Barcelona, UAB, (The Autonomous University of Barcelona).
The conference will bring together researchers, engineers, and experts in academia, industry, space agencies, and regulatory organizations around the world to examine progress, challenges and potential solutions. ICSSC 2025 is also a unique occasion for participants to network, strengthen alliances, and establish new partnerships and collaborations.
The 2025 Conference will feature:
- The latest developments in satellite systems for telecommunications, navigation, earth observation, and space exploration
- Innovative advances in Space AI, optical communications, quantum encryption and 3GPP standards with 5G/6G networks interoperability for our space based near Earth, Lunar, and deep Space environments
- Expanding applications with NGSO, and regulatory, business, and technical aspects of direct satellite to cellular mobile service
- Latest results in propagation research at Q/V, E/W, and higher frequency bands, as well as optical scintillation effects
- Emerging techniques in navigation, vehicle autonomy, earth observation, space domain awareness, and human exploration
- Challenges of radio frequency interference, orbital debris control and mitigation, and many more
In addition to the technical content (including keynotes, plenary panels, workshops, and parallel technical sessions for oral presentation of peer-reviewed contributions), ICSSC 2025 offers a rich blend of social events for participants and their companions to enjoy.
