SENTINEL 5P is a cataloged satellite tracked under NORAD ID 42969 with international designator 17064A. According to the GCAT master catalog, it was built by ADSUK, on the AstroSat-L250M platform, with a launch mass of about 820 kg, with a shape described as Hex cyl+3 pan. According to the TLE snapshot used when this page was generated (2026-08-18), its LEO orbit had an apogee of about 835 km and a perigee near 833 km, with an inclination of 98.79° and a period of roughly 101.4 minutes; at apogee its speed was about 7.44 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, SENTINEL 5P's apogee was 835 km, where its speed was about 7.44 km/s, completing about 14.2 orbits of Earth per day. Track it live on the map above or in the JOT orbital map.
