Satellite trackers and networks
Live trackers for the most-watched objects and constellations in orbit. Each one shows real-time positions from CelesTrak data refreshed every 2 hours, plus pass predictions for your location. Two entries are the exception, and say so: the Nancy Grace Roman Space Telescope and James Webb are bound for or already at the Sun-Earth L2 point, a million miles out, where no satellite tracker can follow them.

Navigation
Satellites matching each network's name in CelesTrak's active catalogue, as of 27 October 2026. That includes satellites launched but not yet in service, and it is not the same as the number working: Guowang, for one, is catalogued under the Chinese for “satellite internet, low orbit”, and its test satellites are left out here.
