The Federal Communications Commission voted unanimously on July 22, 2026, to replace its decades-old Part 25 satellite licensing rules with a new regulatory framework called Part 100. Under the new rules, real-time orbital tracking data sharing is now a mandatory condition of every satellite license. Satellite operators serving the U.S. market must continuously transmit precise orbital ephemeris data to an approved space situational awareness (SSA) provider. The FCC satellite tracking mandate marks a fundamental shift. Voluntary space safety practices are now enforceable commercial standards across Low Earth Orbit.
What Part 100 Changes — and Why Now
The Space Modernization Order was adopted at the FCC’s July 22 open meeting. It eliminates Part 25, which had governed satellite licensing since the early era of commercial space. FCC Acting Associate Division Chief Brandon Padgett called Part 100 “a licensing assembly line to expeditiously route space and earth station applications.”
The practical effects are significant. License reviews that previously stretched for years are now expected to compress to months or weeks. The order cuts the standard public notice window from 30 to 15 days for typical applications. The FCC must also place a completed application on public notice — or identify deficiencies — within 30 days of filing.
License terms for most space and earth stations are extended to 20 years under Part 100. The framework allows multiple satellites to co-locate at a single orbital slot. It introduces a new “Variable Trajectory” license category for spacecraft transitioning between orbits. Operators can also make a broader set of minor modifications without seeking prior FCC approval.
FCC Chairman Brendan Carr framed the overhaul in strategic terms. “Getting the regulatory framework right will determine if America wins this Space Race 2.0,” Carr said in a statement accompanying the vote. He described the old rules as designed for small satellite fleets — not modern mega-constellations.
The FCC Satellite Tracking Mandate: From Voluntary to Required
Embedded within the streamlined licensing framework is the provision that drew the most attention from space safety analysts. All Part 100 licensees must share real-time ephemeris data — precise orbital position and velocity information — with an approved SSA provider.
Approved providers include the U.S. Space Force’s 18th Space Defense Squadron, the primary U.S. government entity responsible for space object cataloguing. Alternatively, operators may use a commercial SSA provider. The FCC’s Space Bureau approves those providers and maintains an official list.
The mandate applies as a condition of licensing. Operators cannot obtain or retain a Part 100 license without actively participating in continuous orbital data sharing. Previously, sharing ephemeris data with SSA services was considered a best practice rather than a legal obligation.
The FCC linked the requirement directly to collision risk reduction. Conjunction assessments calculate how close two orbiting objects will come to each other. As LEO grows more crowded, those assessments depend heavily on fresh, accurate tracking data. Stale or incomplete data translates directly into worse predictions and higher collision risk.
The Collision Risk Context
The data-sharing mandate arrives against a backdrop of sharply deteriorating LEO conditions. According to ESA’s Space Debris Office, LEO debris collision risk rose approximately 20 percent since 2024. The European Space Agency estimates roughly 54,000 objects larger than 10 centimeters are present in Earth orbit. However, only about 40,000 are actively catalogued — leaving a significant fraction of catastrophically dangerous debris untracked.
The situation at the 550-kilometer altitude shell is particularly acute. That altitude is the core operating region for large broadband constellations. Debris object density there has reached parity with active satellite density, raising concerns about self-sustaining debris cascades.
A metric known as the CRASH Clock, maintained by the Outer Space Institute, illustrates the operational stakes. Specifically, it estimates how long a catastrophic LEO collision would statistically take if satellites lost the ability to maneuver. As of early May 2026, that estimate stood at approximately 2.5 days. FODNews has covered the CRASH Clock’s compression from 11 days in January 2023 to just 2.5 days. That rapid tightening reflects how quickly LEO conjunction rates are escalating.
FODNews has also reported on the ESA findings that LEO debris collision risk rose 20 percent since 2024. Those findings provide additional context for the regulatory urgency behind the FCC’s move.
Better ephemeris data does not remove debris. However, it substantially improves conjunction assessment accuracy, allowing operators to make better-informed decisions about whether and when to maneuver. The FCC’s mandatory sharing requirement aims to eliminate gaps in that data stream. Historically, operators had little commercial incentive to share precise tracking information with competitors or government bodies.
Architecture of the New Framework
Part 100 organizes into four structural subparts: General; Applications and Licenses; Operational Rules; and Compliance. The application process replaces the legacy Schedule S. Two new schedules take its place: Schedule O covers orbital characteristics, and Schedule F covers frequency use. Both are filed on FCC Form 312.
The framework adopts a certification-based processing approach. If an application meets the FCC’s established bright-line rules, the agency presumes it serves the public interest and grants it. This replaces case-by-case merits analysis, reducing the unpredictability that had made long-range commercial planning difficult.
For non-geostationary orbit (NGSO) constellations, processing rounds are restructured into annual, band-specific cycles. Co-filers share equal spectrum priority. The order also expands eligibility for first-come, first-served treatment and eliminates traditional milestone requirements and surety bond requirements for some systems.
In exchange for streamlined entry and a reduced financial burden, operators accept affirmative safety obligations. Specifically, those obligations are the ephemeris data-sharing requirement and periodic space safety reports filed with the FCC. The tradeoff is explicit: faster licensing, but with enforceable accountability for orbital behavior.
Implications for Foreign Operators and Industry
The July 22 vote was unanimous among the three sitting FCC commissioners. Its effects, however, extend beyond U.S. companies. Any satellite operator seeking to serve the U.S. market — including Canadian, European, and Asian firms — must comply with Part 100’s requirements.
The framework introduces what SpaceQ has described as reciprocity scrutiny. The FCC is reviewing the World Trade Organization presumption that grants non-U.S. operators entry to the U.S. market, assessing whether U.S. operators receive equivalent access abroad. For cross-border operators such as Telesat, the dynamic is asymmetric. Telesat Government Solutions, the company’s U.S.-based subsidiary, gains direct access to Part 100’s faster processing. The Canadian parent, however, faces separate FCC review for its orbital assets under the reciprocity framework.
One near-term carveout drew particular notice from industry observers. Applications already pending before the FCC will not automatically fall under Part 100’s revised processing timelines. This includes SpaceX’s plans for up to one million satellites to support artificial intelligence infrastructure demand. The FCC delegated transition mechanics for existing Part 25 licensees to the Space Bureau. That guidance will follow formal publication of the final rules. FODNews has covered the FCC’s evolving spectrum policy, including its earlier Big LEO spectrum ruling affecting SpaceX and Iridium.
Environmental groups also raised concerns during the post-meeting press conference. They questioned whether the accelerated approval process adequately evaluates the ecological impact of large data center constellations. The FCC does not traditionally assess environmental impacts as part of satellite licensing, and Part 100 adds no such mechanism.
The final Part 100 rule text had not been published as of late July 2026. The detailed transition schedule for existing Part 25 operators likewise remained pending. Implementation guidance from the Space Bureau is expected in the months following formal publication of the order.
What the July 22 vote makes clear is the direction of U.S. satellite policy: faster market access, structured around measurable safety obligations. The mandatory sharing of real-time tracking data is the most concrete expression of that principle. A practice that industry once treated as optional has become a non-negotiable condition of doing business in low Earth orbit.
