ORBCOMM FM01

ORBCOMM FM01 is an active satellite operated by ORBCOMM, launched on 1995-04-03 from Vandenberg SFB, California. With over 31 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Low Earth Orbit (LEO) at altitudes between 578 km and 588 km with an inclination of 70.0°. It travels at approximately 27,255 km/h (7.57 km/s), completing one full orbit every 96 minutes — that’s roughly 14.95 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. It is part of the Orbcomm constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks ORBCOMM FM01 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

ORBCOMM FM01 orbits in the most densely populated region of Low Earth Orbit, between roughly 300 and 600 km altitude. This band is home to the International Space Station, most Earth observation satellites, and the bulk of the Starlink constellation. Objects here experience measurable atmospheric drag, which gradually lowers their orbit over months to years and eventually causes re-entry. The relatively short signal path makes this altitude ideal for low-latency communications and high-resolution imaging.
