About This Satellite
The International Space Station is the largest crewed structure ever placed in orbit. Assembled from modules contributed by the United States, Russia, Japan, Canada, and the European Space Agency beginning in 1998, it circles Earth roughly every 92 minutes at an altitude near 420 km and has hosted rotating international crews continuously since November 2000.
ISS (ZARYA) is a cataloged satellite tracked under NORAD ID 25544 with international designator 98067A. According to the GCAT master catalog, it was built by KHRR, on the 77KS platform, with a launch mass of about 20281 kg, with a shape described as Cyl + 2 Pan. It is associated with RU, US. According to the TLE snapshot used when this page was generated (2026-08-18), its LEO orbit had an apogee of about 430 km and a perigee near 420 km, with an inclination of 51.63° and a period of roughly 92.9 minutes; at apogee its speed was about 7.65 km/s. It was launched on 1998-11-20. Alternative names include ZARYA, RS0ISS, NA1SS. Positions on this page are near-real-time SGP4 predictions propagated from the latest two-line element (TLE) data.
