Upper C-Band Transition: What the FCC’s $6.3 Billion Clearing Plan Means for Satellite Operators

The Upper C-band transition is the largest US spectrum move affecting satellite operators since the Lower C-band clearing of 2020 to 2023. The FCC’s first estimate puts clearing costs at $4 billion to $5 billion, it has set aside $6.3 billion in incentive payments for the satellite companies, and the timetable runs to mid-2031.

The 19 October 2026 Federal Register moved the process into its practical phase. The rules on transition plans and lump sum payments are now in force, and the Wireless Telecommunications Bureau asked for comment on two documents that will decide who gets paid what.

What the FCC decided

The Commission adopted its Report and Order, Order of Proposed Modification, and Order on Reconsideration (FCC 26-46) on 22 July 2026. A summary was published in the Federal Register on 31 July 2026 at 91 FR 48700, and most of the rules took effect on 29 September 2026.

The order was driven by Congress. Section 40002 of Public Law 119-21, the statute the FCC calls the One Big Beautiful Bill Act, restored the Commission’s general auction authority and told it to complete an auction of at least 100 megahertz between 3.98 GHz and 4.2 GHz within two years of enactment. That means by 4 July 2027.

The FCC went further than the minimum. It will auction 160 megahertz at 3.98-4.14 GHz, folded together with the Lower C-band into a single “3.7 GHz Service” that runs from 3.7 GHz to 4.14 GHz. It added a mobile allocation to 4.0-4.16 GHz and removed the fixed-satellite allocation from that range in the contiguous United States. It set 4.14-4.16 GHz aside as a guard band and kept 4.16-4.2 GHz for satellite downlinks. Outside the contiguous United States nothing changes.

The legal tool is section 316 of the Communications Act, which lets the FCC modify existing licences in the public interest. Every C-band space station operator’s authorisation is modified to limit its operations in the contiguous United States to 4.16-4.2 GHz.

Who has to move, and how

The order identifies three “eligible space station operators”: SES, Eutelsat and Telesat. Intelsat is not listed separately: SES completed its acquisition of Intelsat on 17 July 2025. SES and Eutelsat, the FCC notes, account for the vast majority of existing C-band satellite operations.

The satellite operators run the transition for their customers. The FCC says the work may combine three approaches: repacking existing services into the 40 megahertz left at 4.16-4.2 GHz, moving some services or links to the Ku-band, and hybrid designs that keep a C-band uplink but send the downlink in Ku-band. The record suggested that no new C-band-only satellites would be needed for the repacked services. Where operators do need new Ku-band capacity, the cost can be claimed, subject to review.

The earth station side is the more delicate part. The FCC decided not to reopen the list of incumbent earth stations. It is reusing the Lower C-band definitions and list, which the order describes as having started from more than 17,000 entries. Earth stations that were not on that list, or that have since been moved or expanded, are not treated as incumbents and fall outside the reimbursement scheme.

The deadlines

There are two clearing deadlines, set by Partial Economic Area (PEA). The Primary Transition Deadline is 30 December 2030. It covers the top 75 PEAs, which the FCC says hold about 70% of the US population. It was chosen to match the FAA’s first deadline for retrofitting aircraft radio altimeters, so that new licensees can switch on across the full 160 megahertz in those markets from 31 December 2030.

The Final Transition Deadline is 30 June 2031 for all remaining PEAs in the contiguous United States. Terrestrial use there can start on 1 July 2031, or earlier once every satellite operator’s certificate for that market has been validated and its incentive payment made.

Before either deadline, each operator must publicly file a Transition Plan by 5 November 2026. Under new section 27.1412(e) of the FCC’s rules, which took effect on 19 October 2026 according to the effective-date notice, the plan must list the satellites to be repacked, any new satellites the operator needs and why, a grooming plan showing each customer’s frequencies before and after, technology upgrades, and the earth station antennas that will have to be transitioned.

The money: reimbursement plus incentives

Under the FCC’s “Emerging Technologies” precedent, new licensees must pay the reasonable and necessary costs of moving the incumbents as a condition of their licences, even above the FCC’s $4 billion to $5 billion estimate. A third-party Upper C-band Clearinghouse will administer the claims.

On top of reimbursement, winning bidders must pay incentive payments to satellite operators that clear on time. The FCC sized the pool at $6.3 billion, the value it calculated bidders gain from getting the spectrum faster, with $4.914 billion attached to the primary deadline and $1.386 billion to the final deadline. It rejected the operators’ own allocation proposals and instead modelled how much spectrum each operator would block if it alone failed to clear. SES qualifies for up to $5.607 billion (89%), of which $4.373 billion depends on the primary deadline. Eutelsat qualifies for up to $504 million (8%), and Telesat for up to $189 million (3%).

Lateness costs money on a sliding scale. The primary deadline payment falls by 7.5 percentage points for each 30-day period of delay, down to 55% for an operator 151 to 180 days late, and to nothing after 180 days. Missing the final deadline forfeits the final deadline payment entirely, and the operator may also lose further cost reimbursement and face penalties for unauthorised transmissions. Operators prove completion with a Certification of Completion, which is deemed validated if no deficiency is flagged within 30 days. If a credible challenge is raised, the Bureau must rule within 60 days of the filing. Delays outside an operator’s control do not count against it.

What was published on 19 October

Three documents appeared on the same day.

The first is the effective-date notice. Alongside the transition plan rule, it brought section 27.1419 into force, which lets an earth station owner take a fixed lump sum per site instead of actual cost reimbursement. The election must be made within 60 days after the Bureau announces the lump sum amounts.

The second is the request for comment on the preliminary cost catalogue (Public Notice DA 26-1049, released on 30 September). The contractor Teltrium built it from the 2020 Lower C-band catalogue, adjusted for inflation, with new categories for this transition. It matters because the Clearinghouse will presume that a claim within the catalogue’s range is reasonable.

A new satellite delivered in orbit on its own launch is estimated at $125 million to $470 million, with insurance of $5.2 million to $28.8 million per satellite. The proposed lump sums for earth stations are $13,722 for a receive-only single-feed antenna, $21,502 for a multi-feed antenna, $27,305 for a gateway antenna and up to $55,985 for a large multi-beam antenna, with an extra $53,604 per site for cable and other multichannel video distributors. Comments were due on 20 October 2026 and replies are due on 9 November 2026.

The third is the request for comment on radio altimeter rebates (DA 26-1076). Radio altimeters work at 4.2-4.4 GHz, and the FAA has ordered retrofits by 30 December 2030 and 31 October 2034. New Upper C-band licensees must fund rebates for eligible aircraft owners, and the FCC capped the rebates for aircraft under the second FAA deadline at $3.5 billion. Comments are due on 26 October 2026 and replies on 16 November 2026.

What it means in practice

For satellite operators, the next year is about the Transition Plan. It becomes the yardstick the Clearinghouse uses to judge claims and the basis for any later argument that a delay was beyond the operator’s control. An operator that plans to buy Ku-band satellites must show why repacking or a hybrid design was not enough, and that choice feeds into procurement and launch and in-orbit insurance on the FCC’s timeline. The usual launch services agreement issues, such as delay and replacement launch, now sit against a hard regulatory deadline.

For earth station owners, the lump sum is the real decision. It is per site and irrevocable, and taking it means doing the work yourself, moving to fibre or IP delivery, or switching off, while still meeting your area’s deadline. For a broadcaster or cable operator with many sites, a mix probably makes sense: lump sums where a site is being retired or moved to IP anyway, actual cost reimbursement elsewhere.

For bidders, the obligations come with the licence. The Auction 115 procedures notice describes 3,248 licences and a tentative start on 27 April 2027. For scale, the Lower C-band auction, Auction 107, raised $81,168,677,645 in gross proceeds.

The wider picture

The FCC’s choices are national, and ITU allocations are not changed by an FCC order. New satellites launched to carry services moved to Ku-band will still need coordination through the ITU filing system. The order sits alongside the FCC’s push to open more spectrum for satellites, covered in our piece on the 12.7 GHz and 42 GHz decision. It also settled old petitions on the 2020 order: telemetry, tracking and command earth stations stay protected at their consolidated sites until 5 December 2030.

What I would watch

The first is the Transition Plans due on 5 November 2026. How much each operator moves to Ku-band, and how many new satellites it claims, will drive the reimbursement bill.

The second is the final cost catalogue and lump sum amounts. The figures so far are preliminary, and the 60-day election clock runs from the Bureau’s announcement, so earth station owners should be ready to decide site by site.

The third is Auction 115. Whether bidding starts on 27 April 2027 and finishes before the 4 July 2027 statutory deadline will show how much the clearing burden weighs on prices.

The fourth is aviation. The primary deadline is tied to the FAA’s first radio altimeter deadline. If retrofits slip, I would expect pressure to move the 30 December 2030 date, and the incentive structure was not built for a moving target.
