About
N2YO.com is one of the most comprehensive and widely used free satellite tracking platforms on the web. It monitors over 34,000 orbiting objects in real time — from the International Space Station and Chinese Space Station to weather satellites, military satellites, GPS constellations, Starlink and Kuiper networks, amateur radio satellites, and newly launched objects. The platform delivers live orbital position data including azimuth, elevation, altitude, speed, right ascension, declination, and satellite period. Users can set a custom location to receive precise pass predictions, knowing exactly when and where a satellite will cross their sky. Alerting tools notify users of upcoming ISS passes via email or SMS, and a voice-based prediction service is also offered. A standout feature is HD live video streaming directly from cameras aboard the ISS. The satellite database is browsable by launch date, country, category, or owner, and embeddable widgets let website owners display live tracking data on their own pages. A REST API provides programmatic access to real-time TLE data, pass predictions, and orbital parameters, making N2YO a valuable backend resource for developers building space-related tools and applications. N2YO is ideal for amateur astronomers, ham radio operators, space enthusiasts, students, researchers, and developers. Its enormous satellite database, completely free access, and no-account-required experience make it the go-to web resource for satellite monitoring worldwide.
