The regulatory milestones of the first half of 2026 have fundamentally rewritten the operational requirements for space. This is the second post in our three-part series on the operational impacts of H1 2026 regulatory milestones. In part one, we covered how the FCC is using financial penalties to enforce automated debris reporting. Now we look at how the ITU is eliminating speculative spectrum hoarding.

Holding spectrum on a spreadsheet is now a fast track to losing your filing. The ITU Radiocommunication Bureau published a new circular clarifying the physical deployment milestones for non-geostationary satellite networks. The era of the paper satellite is officially over. Operators must now provide verifiable manufacturing contracts and launch reservations by the four-year mark to retain their priority spectrum rights.

This directly impacts the spectrum hoarding strategies we analyzed when we covered the death of EPFD limits. With legacy Equivalent Power Flux Density constraints sidelined, the ITU is shifting to real-time database models for dynamic spectrum sharing. You need physical assets and active coordination to keep your frequency rights.

Here are the three operational impacts of the new itu milestone requirements that will reshape how startups build and fund their constellations.

The four-year manufacturing cliff

The ITU timeline for physical deployment is unforgiving and strictly enforced. You have two years to complete international coordination. You have four years to prove manufacturing contracts. You have seven years to deploy the first batch of satellites. Missing any of these milestones triggers an automatic reduction in your authorized constellation size.

This creates a massive problem for startups relying on speculative spectrum valuations for fundraising. Investors can no longer value a company based on theoretical spectrum holdings. You must have signed manufacturing agreements to prove you will actually use the frequency.

After all, the ITU is prioritizing operators who are actually building hardware over those who are just filing paperwork. If your business model relies on holding spectrum rights without physical production, your valuation is about to drop to zero.

Funding the RF coordination phase

The coordination phase is where most operators will fail the new itu milestone requirements. The ITU requires proof that you have actively engaged with foreign administrations to resolve interference claims. You cannot simply submit a filing and wait for objections.

You must fund the RF engineering teams required to run interference simulations and negotiate mitigation terms. This shifts the financial risk of spectrum coordination to the very beginning of the mission lifecycle. We explored the jurisdictional risks of this in our analysis of country of registry obligations. Your flag state is now financially on the hook if you fail to meet ITU deployment milestones.

In a nutshell, spectrum coordination is no longer a legal exercise. It is a heavily capitalized engineering operation. You need to budget for dedicated RF teams on day one, not after you secure your Series A funding.

The end of theoretical constellation sizing

Missing an ITU deployment milestone triggers an automatic reduction in your authorized constellation size. If you fail to prove manufacturing contracts by year four, the ITU will shrink your approved network. This means your financial models, link budgets, and coverage maps must be recalculated based on a smaller physical footprint.

This forces operators to design flexible constellation architectures. You cannot build a rigid business plan around a 500-satellite network if your manufacturing supply chain only supports 200 satellites by the four-year deadline.

At the end of the day, the itu milestone requirements have tied spectrum rights directly to physical production capacity. The operators who align their manufacturing timelines with their ITU filing dates will secure their spectrum. The operators who treat spectrum as a purely financial asset will lose it.
