HBTSS-SV1

HBTSS-SV1 is an active satellite operated by United States, launched on 2024-02-14 from Cape Canaveral, Florida. It orbits in Low Earth Orbit (LEO) at altitudes between 566 km and 582 km with an inclination of 40.0°. It travels at approximately 27,273 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 14.98 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks HBTSS-SV1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

HBTSS-SV1 orbits at an average altitude of 574 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 HBTSS-SV1’s average altitude, there are currently 3,161 active payloads and 497 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-1522, STARLINK-2112. This makes it one of the more crowded altitude bands, containing roughly 18.2% of all active satellites. With an inclination of 40.0°, HBTSS-SV1 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 12,339 active satellites in total, of which 2,619 share a similar altitude band with HBTSS-SV1.
