Satellite tracking and a registry of what is in orbit.
Orbit is getting crowded. GC GO shows tracked objects on a live map and in a searchable registry, in the same place as launches, space weather and the policy that governs them.

Live tracking
See what is up there, and look up any object.
Live Tracking shows objects in orbit on a 2D map, in 3D, or both together. Filter the view, pick an object and read its details.
The Object Registry lists tracked objects from the public satellite catalog. Orbital data comes from public sources, including CelesTrak.
Positions are propagated from published orbital elements using the standard SGP4 model. That is the right tool for awareness and planning. It is not precise orbit determination, and it should not be used on its own for collision-avoidance decisions.

What a TLE is, and why freshness matters.
A two-line element set, or TLE, is a compact description of an object's orbit at a moment in time. Software feeds it into the SGP4 model to estimate where the object is now and where it will be later.
The estimate degrades as the element set ages, faster in low orbits where drag is strong and during geomagnetic storms. That is why the age of the data matters as much as the position it gives.
The main orbit regimes.
| Regime | Altitude | Typical use |
|---|---|---|
| LEO (low Earth orbit) | Below 2,000 km | Earth observation, broadband constellations, crewed stations |
| MEO (medium Earth orbit) | 2,000 to 35,786 km | Navigation constellations |
| GEO (geostationary orbit) | 35,786 km | Communications, weather |

Common questions.
Where does the orbital data come from?
From public sources, including CelesTrak and the public satellite catalog.
How accurate are the positions?
Positions are propagated with the SGP4 model from published orbital elements. They are suitable for awareness and planning, not for precise orbit determination or collision-avoidance decisions on their own.
Can I search for a specific satellite?
Yes. You can search and filter objects on the map and in the Object Registry.
Why track objects on a business platform?
Because mission decisions depend on more than one kind of information. Orbital context sits next to launch activity, space weather and the policy that applies.
