VELOX C1

VELOX C1 is an active satellite operated by Nanyang Technological University (Singapore), launched on 2015-12-16 from SRI. After 11 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 414 km and 420 km with an inclination of 15.0°. It travels at approximately 27,587 km/h (7.66 km/s), completing one full orbit every 93 minutes — that’s roughly 15.50 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 VELOX C1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

VELOX C1 orbits at an average altitude of 417 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 VELOX C1’s average altitude, there are currently 2,606 active payloads and 119 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1020. This makes it one of the more crowded altitude bands, containing roughly 15% of all active satellites. With an inclination of 15.0°, VELOX C1 passes over latitudes between 15.0°N and 15.0°S, concentrating coverage over equatorial and near-equatorial regions. Low-inclination orbits maximise revisit rates over specific tropical zones. Singapore operates approximately 14 active satellites in total, of which 2 share a similar altitude band with VELOX C1.
