HBTSS-SV2

HBTSS-SV2 is an active satellite operated by MDA (United States), launched on 2024-02-14 from Cape Canaveral Space Force Station, United States on the HBTSS/SDA-0C launch. It orbits in Low Earth Orbit (LEO) at altitudes between 984 km and 1,011 km with an inclination of 40.0°. It travels at approximately 26,478 km/h (7.35 km/s), completing one full orbit every 105 minutes — that’s roughly 13.70 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~100–500 years. Orbital Radar tracks HBTSS-SV2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HBTSS-SV2 orbits at an average altitude of 998 km in the upper LEO band, where atmospheric drag is negligible and objects can persist for centuries to millennia. This altitude is used by broadband constellations like OneWeb and by scientific missions requiring stable orbits far from the densest debris bands. Within ±50 km of HBTSS-SV2’s average altitude, there are currently 305 active payloads and 1,069 tracked debris or rocket body fragments. With an inclination of 40.0°, HBTSS-SV2 passes over latitudes between 40.0°N and 40.0°S, covering the tropical and temperate zones where most of the world’s population resides. Low-to-mid inclination orbits are efficient to reach from equatorial and mid-latitude launch sites. United States operates approximately 13,204 active satellites in total, of which 80 share a similar altitude band with HBTSS-SV2.
