Cosmotrak - Satellite Tracker

Explore Earth orbit and the solar system with Cosmotrak.

Cosmotrak combines satellite tracking, accurate pass predictions, AR sky guidance, space launch schedules, spaceflight news, and an interactive celestial map in one beautifully designed app.

TRACK SATELLITES

Follow the ISS, Starlink, weather satellites, navigation constellations, scientific missions, and thousands of other objects orbiting Earth.

• View current satellite positions on a native 3D globe
• Search and filter the satellite catalog
• Track individual satellites or complete categories
• See upcoming passes calculated for your location
• Follow satellite ground tracks on a 2D map
• Use widgets for pass information at a glance

FIND SATELLITES IN AR

Select a satellite and open the AR Satellite Finder to see where to look in the sky. Cosmotrak combines your location, device orientation, and current orbital data to guide you toward the satellite's position.

If a satellite is below the horizon, Cosmotrak clearly shows its direction and elevation without placing a misleading marker in the sky.

EXPLORE THE CELESTIAL MAP

Travel beyond Earth with an interactive, Metal-powered map of the solar system.

• Explore the Sun, Mercury, Venus, Earth, the Moon, Mars, Jupiter, and Saturn
• Focus on planets, moons, and historic spacecraft such as Voyager
• View detailed celestial imagery and physical facts
• Examine atmospheric composition, pressure, density, temperature, and other scientific data
• Move forward or backward through time to watch the solar system evolve
• Browse available ephemeris coverage and data-source information

PLAN YOUR NEXT SATELLITE PASS

Cosmotrak calculates observer-specific passes using your location and current orbital data.

LOCATION AND PRIVACY

Cosmotrak uses your location to calculate observer-specific satellite passes, sky directions, and local viewing conditions. You can also configure a custom observer location from Settings.

Camera access is requested only when you open the AR Satellite Finder.

Whether you are watching the ISS cross the night sky, following a rocket launch, exploring Saturn, or checking the position of Voyager, Cosmotrak gives you a new way to understand what is above us and what lies beyond.
