IAU CPS Technical Recommendations

The IAU CPS consolidated technical requirements provide guidance for satellite operators, manufacturers, and related industry professionals to minimise the impact of satellite constellations on astronomy. We are regularly updating them to match new developments in the satellite constellation industry, based on the latest observations and analysis from the astronomical community.

In February 2024 we released our first draft of the IAU consolidated recommendations. They are complemented by the IAU CPS Position Paper, released in March 2024, which describes our policy position.

Our recommendations are based on collaborative input from astronomers, engineers, and other stakeholders, and we are regularly updating them as satellite populations evolve. We expect to release the next version in early 2025.
