Satellite leasing applies the asset-backed model that financed most of the world's commercial aircraft to communications spacecraft and the ground stations that control them. More than half of the commercial aircraft fleet is leased. Fewer than 5% of space assets are financed the same way, which leaves operators funding hardware worth hundreds of millions from equity, grants and corporate debt. Caelum buys revenue-generating satellites and ground stations and leases them back to the operators that run them.
How a satellite sale-leaseback works
The operator sells the asset to a Caelum entity, a Section 110 DAC established for that transaction, and immediately leases it back for a term matched to the asset's contracted revenue and remaining life. The operator receives the purchase price up front and keeps full operational control. At the end of the lease it typically holds a purchase option.
What changes is ownership of the hardware and nothing else. The operator keeps the orbital slot and the spectrum filings, which sit with the licensee rather than the owner of the spacecraft. It keeps its customer contracts, its ground segment and its flight operations. What it hands over is the residual value, the piece a lessor exists to price.
- The asset. We start with the satellite or ground station, the operator and the revenue contract behind it.
- The structure. We design the financing around the asset and contract profile, with one Section 110 DAC per transaction.
- The capital. Senior lenders, export-credit cover and equity co-investors come into each deal. The operator is funded without diluting its equity.
- The life of the lease. Caelum stays alongside the operator through the term, supporting refinancing, fleet growth and further assets.
Four ways to finance a satellite or ground station
| Structure | Asset | When capital arrives | Launch risk |
|---|---|---|---|
| Sale-leaseback at in-orbit delivery | New satellite on order, with a capacity contract behind it | At in-orbit acceptance | Operator, manufacturer and their insurers |
| Sale-leaseback at factory delivery | New satellite that needs financing before it ships | At manufacturer acceptance, before launch | Insured, with the lessor as loss payee |
| Refinancing in-service satellites | Satellites already in orbit and earning | At closing | None: the asset is in service |
| Ground stations and TT&C | Teleports, gateway earth stations, TT&C facilities | At closing | Not applicable |
In-orbit delivery is where most new-build transactions start. Caelum acquires the spacecraft once it has been delivered in orbit and accepted, so launch and early-orbit risk stay with the operator, its manufacturer and their insurers. The mechanics of the handover are set out in in-orbit delivery explained.
Factory delivery serves an operator that needs its build-phase funding taken out before launch. Caelum buys the completed satellite at manufacturer acceptance, launch and in-orbit-test cover is placed with the lessor as loss payee, and lease payments begin at in-orbit acceptance. It is offered once the programme's first in-orbit transactions have closed.
In-service refinancing releases capital already sitting in the fleet. The operator keeps flying the satellite and collecting from its customers, and the proceeds refinance maturing debt or fund the next spacecraft, with an operating track record to underwrite against.
Ground stations sit in one jurisdiction, carry conventional security and usually close fastest, which makes them a practical first transaction for an operator new to leasing. See ground station financing for how teleport transactions are structured.
What Caelum finances
GEO and MEO communications satellites, in service or acquired at delivery, and the ground segment that supports them: teleports, gateway earth stations and telemetry, tracking and command facilities. We focus on revenue-generating assets with contracted cash flows.
| GEO communications satellite | Ground station | |
|---|---|---|
| Structure | Sale-leaseback / finance lease | Sale-leaseback / finance lease |
| Facility size | €100M+ | Typically €10–50M |
| Term | Up to 15 years | Matched to asset life and contracts |
Why operators lease satellites
Capital comes back into the business. A sale-leaseback converts an asset already paid for into cash for the next spacecraft, the next market or debt that is coming due.
The cap table stays as it is. The financing sits at asset level. No new shareholders, no board seats and no valuation round.
The funding is priced off the asset. Under IFRS 16 the lease is recognised on balance sheet either way. The benefit is capital released and a second source of funding priced against the satellite and its contracts, with accounting treatment confirmed transaction by transaction.
The term follows the technology. Lease terms aligned to technology cycles mean an operator is not locked into hardware it would rather replace. Life extension is changing that calculation, as set out in satellite life extension and the lease term.
Why Dublin
Caelum Space Leasing Limited is headquartered in Dublin. Ireland is the global centre of aircraft leasing, with decades of structuring, legal, tax and regulatory depth, a double-taxation treaty network covering more than 70 countries and courts experienced in asset finance disputes. Each transaction is held in its own Section 110 DAC. Caelum's founder brings more than twenty years of aviation and maritime structured finance and leasing to the space sector. The reasoning is set out in from aviation to orbit.
Satellite leasing: common questions
What is satellite leasing?
A lessor owns the satellite or ground station and the operator uses it under a long-term lease, paying rent instead of funding the asset outright. In a sale-leaseback the operator sells an asset it already owns, or has on order, to the lessor and leases it straight back.
Does the operator lose control of the satellite?
No. The operator keeps flying the spacecraft and keeps the orbital slot, spectrum filings, customer contracts and ground segment. Only ownership of the hardware moves to the lessor's SPV.
Who carries launch risk?
On in-orbit delivery transactions, neither Caelum nor its funding partners carry launch exposure: the spacecraft is acquired after it has been accepted in orbit. Factory-delivery transactions are insured through launch and in-orbit testing, with the lessor as loss payee.
How large and how long are the leases?
Satellite facilities are typically €100M or more with terms of up to 15 years. Ground station transactions are typically €10–50M.
