TL;DR: The FCC is replacing Part 25, its long-standing rulebook for satellite and earth station licenses, with a new Part 100 built around what it calls a "licensing assembly line." Applications that follow the rules are presumed acceptable, forms are standardized and certification-based, and the agency has to explain itself if it has not acted within 60 days after public comment closes. On October 26, the Federal Register published the follow-on proposals that came with the order, opening comments until November 25. For space companies, licensing is becoming faster and more predictable, which changes how you plan, sell and talk about your timeline.

Key takeaways

• Part 100 replaces Part 25 with modular, certification-based applications and a "default to yes" review for requests that comply with the rules.
• Within 30 days of filing, the FCC will either put an application on public notice or say what is missing, and typical requests sit on public notice for 15 days.
• New categories cover orbital transfer vehicles, in-space servicing and commercial lunar spacecraft, and hosted payload arrangements are explicitly allowed.
• Further proposals on space experimental licenses, hosted space stations, secondary markets, a U.S.-based control point and cybersecurity are open for comment until November 25, 2026.
• The date Part 100 actually takes effect is still to be announced by the FCC's Space Bureau, so plan for a transition period.

What did the FCC change?

The FCC adopted its Space Modernization for the 21st Century order (FCC 26-47) on July 22, 2026. It creates Part 100, a new rule part for licensing and operating space stations and earth stations, to replace Part 25, which the order itself calls "a confusing tangle of application and operational rules." On October 26, the Federal Register published the Further Notice of Proposed Rulemaking that came with the order, which started the clock on public comments. Payload has also published a guide to what the framework means for space companies.

Here is the short version of what the order does:

• Presumed acceptable. If a request complies with the rules, the FCC presumes it is in the public interest and focuses review on the parts that do not, such as waivers, foreign ownership, market access and federal coordination.
• Standard forms instead of long narratives. Applicants file Form 312 plus standard schedules built on certifications, with far fewer free-form technical narratives. An approved Form 312 can be reused across applications, and companies can get it pre-cleared before they file for a specific system.
• Clear handling timelines. Within 30 days of filing, the FCC either places an application on public notice or tells the applicant what is missing. Typical requests stay on public notice for 15 days, and if no action comes within 60 days after comment closes, the FCC must explain why.
• Conditional grants. The FCC can grant a license while federal coordination, commercial coordination or certain orbital debris reviews continue on their own track.
• More system types. Applications can cover GSO, NGSO, multi-orbit systems and a new Variable Trajectory Space Station category, which the FCC expects to include orbital transfer vehicles, some in-space servicing and commercial lunar spacecraft. Hosted space station arrangements are explicitly allowed.
• Faster earth stations. A new Nationwide, Non-Site license lets operators register many similar earth stations over time, and qualifying operators can start on a non-interference, unprotected basis once their application goes on public notice.
• Predictable processing rounds. Annual processing rounds for certain bands open automatically on January 1 and close October 31, and operators opt in.

The order says it takes effect 60 days after its own Federal Register publication, but most Part 100 rule sections wait on a federal paperwork review, and the Space Bureau will announce the "Part 100 Effective Date" by public notice. On that date, existing licensees must comply with Part 100, subject to the conditions on their current licenses.

Why does FCC Part 100 matter to space entrepreneurs?

Licensing is one of the slowest, least predictable steps for many satellite, ground segment and in-space companies. When the timeline is unclear, it drags on everything else: launch planning, customer contracts, investor updates and hiring.

Part 100 aims to make that step more like a checklist. If your system fits inside the rules, you can certify to that and expect a faster path. If it does not, you know early which parts will get a closer look. That predictability is valuable to the people you sell to and raise from, not just to your regulatory team.

It also widens the door for business models that never fit neatly under Part 25. Spacecraft-as-a-service and hosted payload providers, orbital transfer vehicle builders and lunar companies now have named lanes in the rules.

Who wins and who loses from FCC Part 100?

This is our reading of the order, not a finding from the FCC or Payload. Real results depend on how the Space Bureau runs the transition and how the FCC handles the open proposals.

Likely winners

• Companies with standard, rule-compliant systems. The more you can certify, the more you benefit from the presumption of acceptability.
• Hosted payload and spacecraft-as-a-service providers. The order names hosted arrangements and says it wants straightforward licensing for them.
• Orbital transfer, in-space servicing and lunar companies. The new Variable Trajectory category gives these systems a home.
• Ground station networks. The Nationwide, Non-Site license and early start rules can speed up multi-site rollouts.
• Repeat applicants. Reusing an approved Form 312 cuts duplicate paperwork.

Likely losers or under pressure

• Teams that rely on waivers. Anything outside the rules still triggers targeted review, so the speed gap between standard and unusual systems may widen.
• Companies that have not tracked the transition. Existing licensees must comply with Part 100 once it takes effect, and pending applications may need attention.
• Competitors whose pitch leaned on regulatory difficulty. If licensing gets easier, "we already have our license" carries less weight on its own.
• Anyone who skips the comment period. The rules on experimental licenses, hosted stations, control points and cybersecurity are still being shaped.

What should space entrepreneurs do now?

Here are five practical moves for founders, marketers and business development teams.

1. Read the order and decide whether to comment

Do not rely on summaries, including this one. Have your regulatory counsel review the order and the open proposals, and decide by November 25 whether you need to weigh in. If the experimental licensing or hosted station proposals touch your roadmap, this is your chance to shape them.

2. Rebuild your timeline story around predictability

Investors and customers ask when you will be licensed. A clearer process lets you give a more confident answer. Update your investor deck and sales materials once your counsel confirms how Part 100 affects your filings, and treat milestones like public notice or a grant as moments worth announcing. Our funding and contract announcement playbook shows how to turn those moments into coverage.

3. Explain regulatory status in plain words

Buyers are not regulatory experts. Tell them what is licensed, what is pending and what it means for their service date, without jargon. Our guide on how to explain complex space technology to buyers covers how to keep it simple without losing accuracy.

4. Position for the new lanes

If you offer hosted payloads, transfer vehicles, servicing or ground networks, Part 100 gives you a clearer story about how customers get to orbit and on air. Say it on your website and in your value proposition: what you provide, how licensing works with you and how you reduce the customer's risk.

5. Turn regulatory wins into proof

A grant is a proof point. When Globalstar hit a key FCC milestone, we showed how to market a regulatory win without overclaiming. Do the same with your own milestones: share the facts, link the public record and explain what it unlocks for customers.

How does this change positioning for space companies?

When a process gets faster, the advantage shifts from simply getting through it to being ready for it. Companies that can certify cleanly, file quickly and explain their status in plain words will look more credible to buyers and investors.
