The registry for orbital infrastructure
Clarke is a live registry of GEO orbital positions — congestion, operators, and FCC filing status — the reference-data layer for a market that runs on PDFs and phone calls.
The Space Economy
Companies in Clarke's registry, organized by where they sit in the value chain — from capital to launch to the satellites and services they power. Click anyone to see what they do.
Capital
The money that funds everything above orbit. Specialist funds underwrite the decade-long bets the public market won't.
Launch & Propulsion
Getting mass to orbit. Launch cost is the master variable — when it collapses, everything downstream becomes possible.
Spacecraft & Systems
The satellites themselves: buses, power, robotics, and the components that survive years in vacuum.
Satellite Operators
Who actually owns and runs fleets in orbit — the layer that holds the spectrum, the slots, and the customer relationships.
Ground & Compute
The invisible half of every satellite: antennas, gateways, and on-orbit processing that turn signals into usable data.
Applications & Data
Where orbit meets a customer. Raw imagery and RF become maritime intelligence, crop forecasts, and trading signals.
In-Orbit Services
A new economy in orbit itself: refueling, servicing, debris removal, and knowing what is where.
Frontier & Beyond
Past Earth orbit: the Moon, habitats, mining, in-space food and manufacturing, and planetary-scale engineering.
Defense & National Security
The largest customer in space. Intelligence satellites, missile warning, and the contractors that build them.
Risk & Insurance
The market that prices failure. Underwriters quantify launch and in-orbit risk for every asset above.
Counts labelled “sats” are satellites in orbit (Clarke registry / UCS) and may lag the latest launches. Tickers shown for public companies; figures for private companies are last reported valuations. Built from public data.
