STRIX-9

STRIX-9 is an active satellite operated by Synspective (Japan), launched on 2026-09-02 from Rocket Lab Launch Complex 1, New Zealand on the StriX-9 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 537 km and 582 km with an inclination of 38.0°. It travels at approximately 27,302 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 15.02 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks STRIX-9 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

STRIX-9 orbits at an average altitude of 560 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 STRIX-9’s average altitude, there are currently 1,283 active payloads and 460 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 6.8% of all active satellites. With an inclination of 38.0°, STRIX-9 passes over latitudes between 38.0°N and 38.0°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. Japan operates approximately 210 active satellites in total, of which 53 share a similar altitude band with STRIX-9.
