📖 About This Object
GLOBALSTAR M015 is an active satellite operated by Globalstar (Globalstar), launched on 1998-04-24 from Cape Canaveral, Florida. With over 28 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 1,907 km and 1,929 km with an inclination of 52.0°. It travels at approximately 24,964 km/h (6.93 km/s), completing one full orbit every 2 hours 5 minutes — that’s roughly 11.49 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is thousands of years. Orbital Radar tracks GLOBALSTAR M015 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
GLOBALSTAR M015 orbits at an average altitude of 1,918 km in the uppermost reaches of Low Earth Orbit. At this altitude, orbital decay is effectively zero without active deorbiting, and coverage footprints are significantly larger than lower LEO, though at the cost of higher latency. Within ±50 km of GLOBALSTAR M015’s average altitude, there are currently 5 active payloads and 17 tracked debris or rocket body fragments. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 52.0°, GLOBALSTAR M015 passes over latitudes between 52.0°N and 52.0°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. Globalstar operates approximately 84 active satellites in total, of which 5 share a similar altitude band with GLOBALSTAR M015.
🔗 Globalstar Constellation

This satellite is part of the Globalstar constellation, a LEO mobile satellite communications system providing voice, data and IoT services. The second-generation constellation operates 24 satellites at approximately 1,414 km altitude with a 52° inclination. Globalstar also provides the backbone for Apple's Emergency SOS via satellite feature on iPhones.

Yes — Orbital Radar tracks GLOBALSTAR M015 (NORAD ID 25308) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
GLOBALSTAR M015 travels at approximately 24,964 km/h (15,512 mph) — roughly 6.93 km/s. It completes 11.49 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 23 sunrises and sunsets every 24 hours.
