The service stations of space
Commercial and government satellites are flying overhead right now. Thousands are already dead in orbit. Europe helped build that fleet — what it still lacks is civil propellant tankers. OrbiitIndhan builds that leg.
For advisors and Europe’s space-transportation community. Explore the live fleet data, then tell us what lands. Early stage — not a flight claim.
Thousands of satellites are already dead in orbit
Every one was launched at real cost. When fuel runs out or hardware fails, the satellite keeps circling as dead weight and operators face a full replacement cycle. Below: the full catalog from GCAT and Tilebox, plus the servicing-addressable slice we target.
Every dead satellite was launched at roughly $3,000 per kg. A typical GEO communications satellite costs $150 to 250M to build and launch. That investment does not disappear when the tank runs dry; the spacecraft keeps orbiting as dead weight.

The propellant window
About 2,000 servicing-addressable satellites carry on-board propellant. Use the live globe above: toggle Propellant view or search the propellant fleet, then click any dot for the fuel gauge and sensor readouts.
Hundreds of satellites are still flying past their design life
Fuel tanks do not come with a public gauge, but launch dates do. These satellites have outlived their planned mission duration. Each one is a commercial decision waiting to happen: launch a replacement, or refuel what already works. That addressable demand is the de-risking Europe’s depot and tanker logistics need — made visible here, not only in a slide.
Oldest still-active satellites past catalog design life, prime refuelling candidates. Purpose from GCAT mission category. Mass, modeled propellant, and illustrative replace-vs-refuel economics from Tilebox.
Europe's orbital neighbourhood
European states and agencies operate hundreds of active satellites across the orbits we plan to service first. That is our home market.
Who flies the satellites we can actually service
Beyond Europe: operators, mission types, India as a launch and operator market, and the rocket stages still circling Earth. All from Tilebox fleet datasets plus GCAT orbital junk.
Propellant tankers for Europe’s satellites
When fuel runs out, operators abandon working satellites. We operate the tanker leg: transfer tanks that deliver propellant — and, when needed, stay as a swappable fuel unit, like an EV battery swap. Designed to align with Europe’s emerging open docking and refilling interfaces (Odyssey / InSPoC direction). We do not invent a competing passive client standard.
Transfer and leave
If the satellite can take propellant, we rendezvous, transfer, and go — the tanker keeps the mission flying without a replacement launch.
Dock a transfer tank
If it cannot, we dock our transfer tank as extra fuel. When empty, we swap it for a fresh one. The tank is meant to carry its own station-keeping and end-of-life path so it does not become debris.
Ecosystem context — not a partnership claim: Europe is converging open rendezvous, docking, and refilling interfaces. We build on the active / tanker side and follow the open passive specs as they land. Our lane is the propellant tanker that keeps depots and clients supplied, plus the demand map above.
Robots do the work. Mission software plans each sortie. Ground demonstrator in design — research stage.
Replace vs refuel, in numbers
Less launch emissions, more mission life
Each step multiplies the climate benefit as propellant stays in orbit, hardware gets repaired, and the network reaches more satellites.
Our engineers come from ISRO, India's national space program. We build the same way: more in orbit, with less.
Help us iterate
Three questions only. Reply in your own words — that is enough for this research stage.
- Is the problem clear?
- Is the opportunity believable?
- Does the live globe help?
