GLOBAL-18

GLOBAL-18 is an active satellite operated by BlackSky Global (United States), launched on 2022-04-02 from RLLC. It orbits in Low Earth Orbit (LEO) at altitudes between 425 km and 430 km with an inclination of 53.0°. It travels at approximately 27,565 km/h (7.66 km/s), completing one full orbit every 93 minutes — that’s roughly 15.46 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks GLOBAL-18 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

GLOBAL-18 orbits at an average altitude of 428 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of GLOBAL-18’s average altitude, there are currently 4,321 active payloads and 143 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1017. This makes it one of the more crowded altitude bands, containing roughly 24.8% of all active satellites. With an inclination of 53.0°, GLOBAL-18 passes over latitudes between 53.0°N and 53.0°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 12,360 active satellites in total, of which 4,076 share a similar altitude band with GLOBAL-18.
