According to the GCAT master catalog, it was built by MOTO/LMMS, on the LM700 platform, with a launch mass of about 662 kg, with a shape described as Box + 2 Pan. According to the TLE snapshot used when this page was generated (2026-08-18), its LEO orbit had an apogee of about 750 km and a perigee near 727 km, with an inclination of 86.45° and a period of roughly 99.4 minutes; at apogee its speed was about 7.48 km/s. Positions on this page are near-real-time SGP4 predictions propagated from the latest two-line element (TLE) data.
In the TLE snapshot used to generate this page, IRIDIUM 911's apogee was 750 km, where its speed was about 7.48 km/s, completing about 14.5 orbits of Earth per day. Track it live on the map above or in the JOT orbital map.
