The satellite industry spent two decades selling connectivity and imagery. The next layer of the low Earth orbit (LEO) economy is not a payload. It is awareness: who is in orbit, where objects are moving, and what they are doing. A handful of companies are building that layer, and capital is following them faster than most constellation operators.
Space domain awareness (SDA) is becoming the traffic control and risk layer of the commercial orbit economy.
LeoLabs moved from collision warnings to AI-driven threat detection with Delta, its new platform.
The 2026 funding wave: Scout Space ($18M), Citra Space ($15M), Neuraspace (~$18M), Project-S (seed).
The space situational awareness market is projected to grow from $1.69B in 2026 to $2.16B by 2030.
Projected active satellites in low Earth orbit
LeoLabs projects more than 70,000 operational satellites in LEO by 2030. Every new constellation adds maneuvers, conjunctions, and objects to track. · LeoLabs / SpaceNews, 2026
Largest commercial catalog of orbital objects
Its radars log roughly 2,000 maneuvers per day and 15,000 radar cross-section measurements daily, with state vectors accurate to under 15 meters. · LeoLabs, 2026
Space situational awareness market, 2030 projection
Up from $1.69 billion in 2026, a 6.4% compound annual growth rate according to Research and Markets. Commercial tracking is the fastest-growing slice. · Research and Markets, 2026
The catalog grew faster than anyone planned
Low Earth orbit is the most crowded industrial zone ever built, and nobody owns a complete map of it. The largest commercial catalog tracks more than 27,000 objects. Its radars log around 2,000 maneuvers a day and 15,000 radar cross-section measurements daily. State vectors land within 15 meters. That precision is the product now.
This is no longer a government-only problem. Public catalogs cover tens of thousands of objects, but commercial operators found the update cadence too slow and the custody gaps too wide. So they pay for the private version.
Seven hundred kilometers up, a misread of 15 meters is the difference between a routine pass and a collision at orbital speed. Debris travels at roughly 7 to 8 kilometers per second. A fragment the size of a coin can disable a satellite. That baseline risk built the category.
Seventy thousand operational satellites are projected to be in LEO by 2030. That is roughly triple today's active fleet. Every new constellation multiplies conjunctions, and every conjunction consumes operator time and fuel.
"Threat detection systems have to be able to keep up with that growth," LeoLabs chief executive Tony Frazier told SpaceNews in April.
The money followed the congestion
The market is still small, and it is compounding at a rate that looks more like software than satellite hardware. Research and Markets sizes space situational awareness at $1.69 billion in 2026, rising to $2.16 billion by 2030, a 6.4% compound annual growth rate.
Scout Space closed an $18 million Series A in May, led by Washington Harbour Partners. The company builds the Owl sensor and its software for space domain awareness, and it is expanding manufacturing in Northern Virginia, including a new 2,600-square-foot facility. Its payload is scheduled to fly on Blue Origin's Blue Ring vehicle.
Citra Space raised $15 million in April for its platform that identifies objects in orbit. Spaceflux, a UK-based network of optical telescopes, pulled £5.4 million in seed funding for AI-powered situational awareness; its sensors combine visible and short-wave infrared (SWIR) imaging, so they can track objects in daylight rather than only at night.
Neuraspace, the Portuguese space traffic management company, took in roughly $18 million in August. As we wrote in August, Neuraspace applies machine learning to conjunction data messages at fleet scale, letting operators screen thousands of satellites with a small team.
In September, Munich-based Project-S exited stealth with a seed round led by Uni.Fund II and backed by the European Space Agency's incubator programs. Project-S is building an end-to-end orbital intelligence and space traffic management system, starting with its own radar payloads, which still need orbital flight qualification before they generate revenue.
LeoLabs itself closed 2025 with more than $60 million in bookings, driven by triple-digit growth in US government contracts. Revenue rose roughly 140% in 2024. The company's product line has expanded from collision avoidance into launch operations and, this year, threat detection.
What it costs to watch orbit now
Ten years ago, tracking orbit meant owning a giant radar dish and a government budget. The cost structure has inverted. Containerized radar now fits on a truck bed, and a new site can stand up anywhere in weeks. The fixed cost of awareness collapsed.
Falling hardware costs do not mean falling margins. The value sits in the data layer: a catalog that is continuously updated, cleaned, and machine-readable. Operators pay for custody and cadence, not for the dish.
What is losing value is the assumption that a public catalog is enough. The US government has opened parts of its tracking data to commercial firms, and the Commerce Department's TraCSS program is building a civil space traffic management system that will buy from commercial providers. The government has become a customer of the layer it used to own.
Insurance is the quiet buyer here. As we wrote in July, orbital debris is becoming an insurable asset class, and underwriters cannot price risk they cannot measure. SDA data is turning into the actuarial table of the orbit economy.
The blockers are real. Radar payloads need orbital flight qualification before they earn anything. Optical networks lose fidelity to weather and geography. And the industry still lacks a shared standard for what counts as a reliable conjunction alert.
2026: from collision warnings to intent
This year the category changed its job description. In April, LeoLabs launched Delta, an AI-powered threat detection and characterization system that replaces its earlier LeoGuard product. Delta moves beyond "something is near" into reading behavior: patterns of life, proximity operations, obscured deployments, maneuvers that look deliberate.
Delta is already in operational use with governments in Europe and Asia, according to Frazier, who declined to name them. "Delta delivers the clarity and speed Allied operators need to make confident decisions, defend critical assets, and strengthen collective security."
The move from position data to behavioral analysis is the same pattern the AI infrastructure market went through: first you instrument, then you interpret. The category has picked up a new name, "orbital intelligence," a deliberate escalation of the word "awareness."
Others are entering. SpaceX unveiled its own space traffic management system in February, a signal that constellation operators want to control their own risk rather than rent it. France's Look Up brought its first Sorasys radar online in April. Turion Space, a startup from Irvine, California, is tracking debris with a 90-kilogram spacecraft using iodine thrusters.
Ground radar, space optics, and the hybrids
The approaches split into three camps, and the differences matter because each has a different cost curve and a different customer.
| Parameter | Ground radar | Space-based optics | Optical network |
|---|---|---|---|
| Weather | ✔ all-weather | ✗ none (in orbit) | ◐ weather-limited |
| Night tracking | ✔ yes | ✔ yes | ◐ SWIR extends to day |
| Smallest debris | ✔ centimetre-class | ◐ metre-class | ◐ metre-class |
| Coverage gaps | ◐ network footprint | ✔ global from orbit | ◐ geography dependent |
| Representative | LeoLabs | NorthStar | Spaceflux |
The pure radar approach, led by LeoLabs, works in all weather, tracks the smallest objects, and closes the busy Southern hemisphere gap. Its weakness is coverage outside its fixed network footprint, which is why the mobile Scout radars exist.
The optical approach is cheaper per site but weaker in bad weather, unless the sensors fly in space, as NorthStar's constellation does, watching orbit from orbit. NorthStar's executives spent early 2026 publicly debating where the industry's bottlenecks sit, a sign the space-based camp is still fighting for its business model.
Spaceflux splits the difference: a distributed optical network with SWIR imaging that pushes observation into daylight.
Who owns the catalog decides the winner. Data is a compounding asset, and every object tracked and every conjunction logged makes the next prediction better. Network effects favor the operator with the largest, cleanest, most continuous dataset. Right now that is LeoLabs, and the distance is not shrinking.
