Live satellites: what is flying overhead right now
OKO computes satellite positions from public orbital data and shows them on a 3D globe — about 840 selected objects, plus more than 10,000 Starlink satellites in dense mode. They are sorted by service: space stations, navigation, geostationary and communication satellites, and the brightest objects visible to the naked eye.
What you will see
Each satellite has a marker by class. Click it to follow it: the camera moves to it and its orbit is drawn as a yellow ring. The International Space Station has a red marker with a permanent label, and its orbit is always shown. The GPS, GLONASS and Galileo navigation systems show why your phone knows where it is, and the geostationary ring above the equator holds television and communication satellites.
Dense mode adds Starlink — about 11,500 objects in total. A space missions layer from Launch Library 2 shows rocket launches from the past 30 days.

How OKO computes positions
Orbital elements (TLE) come from CelesTrak (Dr T. S. Kelso), and the server refreshes them every 6 hours. OKO propagates them with the SGP4 model every second; while you follow a satellite, five times a second, and the followed satellite itself on every frame.
Positions are computed, not directly measured — accurate enough to know where an ordinary satellite is above the Earth, but they are not telemetry.
What you will not find in OKO
OKO does not show the complete catalogue of everything in orbit — only selected groups from CelesTrak. The Chinese BeiDou navigation system, for example, is missing.

FAQ
Where is the ISS right now?
Open the “Track the ISS” link — the camera locks onto the International Space Station and shows its orbit.
Are the positions accurate?
They are computed from public orbital elements with the SGP4 model. That is enough for orientation, but they are not direct measurements.
Why can I not see every satellite?
The normal mode shows about 840 selected objects from CelesTrak groups, and dense mode adds Starlink. OKO does not show the complete catalogue of everything in orbit.
What does a satellite class mean?
The service the satellite provides: space station, navigation, geostationary orbit, communications — or one of the brightest objects visible to the naked eye, which include spent rocket stages.
