Representatives from European radio astronomy observatories and national administrations met at the Paris Observatory to discuss the growing impact of unintended electromagnetic radiation (UEMR) from Low Earth Orbit satellite constellations on astronomical observations.
Participants from Germany, France, Italy, the Netherlands, and Sweden, together with experts from the Committee on Radio Astronomy Frequencies (CRAF) and the Square Kilometre Array Observatory (SKAO), shared recent measurement results, regulatory perspectives, and ongoing dialogue with industry. While UEMR levels are low compared to communication signals, they can still significantly affect the highly sensitive instruments used in radio astronomy.
The meeting strengthened collaboration between science, administrations, and industry, with a shared commitment to continue working toward solutions that safeguard the future of radio astronomical research.
