every satelliteevery orbitfrom European soil
From orbit data to space intelligence:one European platform to connect, analyse and act.
We connect data suppliers, commercial sensor operators and national agencies, with the people who need the data: satellite operators, research institutes, governments and defence organisations. Everything runs on European cloud infrastructure, under European law.
Every orbit shows its source and its age
Hosted in Europe only
- A European companyOVHcloud is a French company, under European law.
- European locations onlyEverything runs on OVHcloud, in France.No data leaves the EU.
- Built in containersEvery release is a set of Docker images, built and checked before it ships.
- Ready to scale outThe same images are ready for Kubernetes clustering and for spreading over several European data centres.
- Ready for any infrastructureEvery part speaks open standards;moving it changes addresses, not code.

How it works
We sit between the sensors that watch space and the people who need to know what's up there.
ESA Test-Bed Telescope 2, La Silla · F. Ocaña/J. Isabel/Quasar SR/ESO · CC BY 4.0Suppliers deliver
Sensor operators and national agencies send us their orbits, observations and non-Earth images (NEI), each as a data product.
SpaceDomain.eu
We check every product, keep track of who licensed what, and enforce it in the Recognised Space Picture (RSpP) database. Every read is logged.
Users act
Operators, researchers, governments and defence see exactly what they licensed, plus the public data.

Everything in orbit, live
Every public object, where it is right now. Each one shows where its orbit comes from and how old it is.
High-interest space objects (HISO)
The satellites in the news this week: manoeuvres, close approaches, re-entries and launches, marked on the globe.
Global Navigation Satellite System (GNSS) health
Galileo, GPS, GLONASS, BeiDou, QZSS and NavIC status, with four maps: interference, flight information regions (FIRs), dilution of precision (DOP) and the ionosphere.
Space news
Upcoming launches with a live countdown, recent launches with the satellites they put in orbit, the spaceflight news, and what satellite observers are writing (open-source intelligence, OSINT), each with the satellites it names.
Analysis tools
Relative motion between two satellites, when a satellite is visible from a place or over an area, and where a launch is going: its expected orbit drawn on the globe.
SpaceDomain mobile
The globe, the filters, the satellite list and high-interest objects all work on your phone.

For users and operatorsComing with accounts
You license data from the suppliers that collect it, and you see exactly what you licensed.
No more, no less.
- Licensed supplier data, orbits, observations, ephemerides and close approaches from the products you license.
- Access enforced in the Recognised Space Picture (RSpP) database, every query is checked against your licences, in the Recognised Space Picture (RSpP) database itself.
- Full audit trail, every read is logged:
who got which data, and when. - Your fleet, your own satellites and the ones you follow, with close-approach alerts at your own thresholds.
- Your own Recognised Space Picture (RSpP), build up your own catalogue of accurate orbits, satellite information and data, right here:
SpaceDomain.eu merges it for you into your organisation's own Recognised Space Picture (RSpP). - An application programming interface (API), for your own systems, using standardized formats from the Consultative Committee for Space Data Systems (CCSDS), the European Space Agency (ESA) and the North American Aerospace Defense Command (NORAD):
Orbit Mean-Elements Message (OMM), Two-Line Element set (TLE), Orbit Ephemeris Message (OEM) and Orbit Parameter Message (OPM).

Observations
Buy the newest Tracking Data Messages (TDM) from sensors on the marketplace.
Track correlation
Match each new track to an object in the reference catalogue.

Fit the observations to an orbit, then propagate it ahead.
Satellite Operations (SATOPS)
Collision Avoidance (CA)
An alert from a Conjunction Data Message (CDM), with its Time of Closest Approach (TCA) and Probability of Collision (PoC).Build the scenario from the two orbits you trust most:your own refined ephemeris, a Two-Line Element set (TLE), or an Orbit Ephemeris Message (OEM) with covariance from the marketplace.
Collision Avoidance Manoeuvre (CAM)
Plan the manoeuvre with both uncertainties shown as ellipsoids, against your own PoC threshold.Then copy or download the post-manoeuvre ephemerides, ready to share with the screening services.
Rendezvous and proximity operations (RPO)

SDA products
Launches
From the launch time and inclination to the right ascension of the ascending node (RAAN), and roughly the orbit.An alert when a launch will be co-planar with your fleet.
Satellite Reconnaissance Advance Notice (SATRAN)
Draw an area on the globe, select satellites and automatically generate reports of when an Intelligence, Surveillance and Reconnaissance (ISR) satellite will be able to see that area:based on the worst-case Field of View (FoV) of the satellite's sensor type, or on the sensor you enter for that satellite.
Fragmentations
From an alert, buy raw Flexible Image Transport System (FITS) images, radar cross sections (RCS) of the debris cloud, and Non-Earth Imaging (NEI) of the event.
Re-entry
A re-entry estimate from Re-entry Data Messages (RDM) and Tracking and Impact Prediction (TIP) messages, and how its window narrows over time.See the ground track across your area of interest (AOI) and the flight information regions (FIR) it crosses, on a day and night map.

Questions
Is it free?
Yes. The live globe and its tools are free, no account needed. Licensed data and the features for organisations come with accounts, in a later release.
Where does the data come from?
From open sources: orbits from CelesTrak and Space-Track, object properties from the European Space Agency (ESA) and its DISCOS (Database and Information System Characterising Objects in Space), and navigation-satellite status from the system operators. Every orbit on the globe names its source.
Who is it for?
Anyone who follows what is in orbit: satellite operators and governments, and also space journalism, space science, astronomy and students of rocket science. The globe, the satellite catalogue and the tools need no account.
Can I use it for space journalism?
Yes. Every orbit shows its source and how old it is, the week's space news from open sources links each story to the satellites it names, and a satellite's newest element set can be copied as an Orbit Mean-Elements Message (OMM) or Orbit Ephemeris Message (OEM) with its source's citation inside it.
Is it useful for astronomy?
For planning observations: Visibility shows when a satellite passes over your site or an area, so you can plan around it or catch it. The orbit data behind it is public and can be copied into your own tools.
What are observations, TDMs and NEI?
Observations are what a sensor measured of an object, such as a telescope’s angles or a radar’s range. A Tracking Data Message (TDM, a CCSDS standard) carries them. Non-Earth imaging (NEI) is a picture of a satellite taken from another satellite or from a telescope on the ground. Both will come from suppliers on the marketplace, with accounts.
Who can get an account?
Organisations: governments, defence, satellite operators, research institutes and the suppliers that provide the data. Accounts aren't open yet.
Is my organisation's data shared with others?
No. What you add about your own satellites is only visible to your organisation, and what you license is never shown to anyone else.
