SNAP-3 EDDIE

SNAP-3 EDDIE is an active satellite operated by US Army Space and Missile Defense Command (United States), launched on 2015-10-08 from Vandenberg Space Force Base, United States on the INTRUDER launch. After 11 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 229 km and 249 km with an inclination of 64.7°. It travels at approximately 27,956 km/h (7.77 km/s), completing one full orbit every 89 minutes — that’s roughly 16.37 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is weeks to months. Orbital Radar tracks SNAP-3 EDDIE in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

SNAP-3 EDDIE orbits at an average altitude of 239 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of SNAP-3 EDDIE’s average altitude, there are currently 62 active payloads and 5 tracked debris or rocket body fragments — notable neighbours include STARLINK-1067, STARLINK-1068, STARLINK-1171. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 64.7°, SNAP-3 EDDIE passes over latitudes between 64.7°N and 64.7°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 13,204 active satellites in total, of which 46 share a similar altitude band with SNAP-3 EDDIE.
