- New seven-year deployment milestones introduced for non-geostationary satellite operators.
- Mandatory reporting and orbit deviation disclosures to enhance spectrum efficiency.
What happened: Stricter timelines and transparency measures for satellite operators
Ofcom, the UK’s communications regulator, has proposed sweeping updates to satellite filing rules to address the rapid expansion of the country’s space sector. The changes target non-geostationary (NGSO) operators, particularly those deploying low Earth orbit (LEO) constellations, with stricter deployment timelines and reporting obligations. Under the new framework, operators must meet four incremental milestones over seven years post-regulatory approval: launching one satellite within seven years, 10% of the constellation within nine years, 50% within twelve years, and full deployment within fourteen years. Failure to comply risks reduced spectrum rights proportional to actual satellite numbers.
Operators will also face enhanced transparency requirements, including quarterly constellation status reports, immediate notification of orbit deviations, and mandatory submission of Equivalent Power Flux Density (EPFD) masks to minimise interference with geostationary (GSO) satellites. Ofcom’s consultation document emphasises that these measures aim to ensure “efficient use of notified frequency assignments and orbital parameters,” critical as competition for limited spectrum and orbital slots intensifies.
The proposals could pressure emerging players like Amazon’s Project Kuiper to accelerate deployments or forfeit spectrum access. Geostationary operators, meanwhile, must declare whether satellites have been operational within the past three years. The consultation period runs until 23 May 2025, with final rules expected in Autumn 2025.

Why it’s important
The UK’s space sector has grown significantly, with satellite broadband, Earth observation, and defence applications driving demand for orbital slots and radio spectrum. However, these resources are finite and require international coordination to avoid interference. Ofcom’s proposed rules align with global standards set by the International Telecommunication Union (ITU), which oversees spectrum allocation.
Stricter deployment milestones address “spectrum squatting,” where operators reserve frequencies without timely launches, blocking competitors. The seven-year full-deployment rule ensures spectrum is used efficiently, while EPFD masks mitigate interference risks between LEO and GSO systems—a growing concern as megaconstellations like SpaceX’s Starlink expand.
The updates also reflect the UK’s post-Brexit regulatory strategy, aiming to attract operators through clearer guidelines. With the global satellite market projected to reach £400bn by 2030, streamlined rules could bolster the UK’s position as a hub for space innovation. However, smaller operators may face higher compliance costs, potentially consolidating market power among larger firms.
