I’m opening this thread to track and share the updates of the PHASMA mission.
PHASMA is a spectrum monitoring and space-based situational awareness mission from the Libre Space Foundation.
The project is about the design and development of two open-source CubeSats. The two CubeSats are tasked to oversee the electromagnetic spectrum and its use in space so that they will perform a series of experiments.
You can find the GitLab repository of the PHASMA project here.
You can join the dedicated Element/Matrix Channel here.
PHASMA is a programme funded by the European Union – NextGenerationEU, and the Greek National Recovery and Resilience Fund, Greece 2.0.
PHASMA satellites are going to be launched on Transporter-15 Rideshare: VSFB SLC-4E : 10 November 2025
Some transmission details:
- UHF Frequency: 400.550 MHz (PHASMA-LAMARR), 400.600 MHz (PHASMA-DIRAC),
- UHF Modulation: FSK
- UHF Buadrate: 50k
- S-band Frequency: 2210MHz (PHASMA-LAMARR), 2208MHz (PHASMA-DIRAC),
- S-band Modulaiton: MSK
- S-band Buadrate: 400k
- Framing: IEEE802.15.4, no reed solomon, ccsds scrambling
After deployment satellites are expected to beacon on both UHF and S-band.
