📖 About This Object
YAOGAN-39 05C is an active satellite operated by PLA Strategic Support Force (China), launched on 2023-12-10 from Xichang, China. It orbits in Low Earth Orbit (LEO) at altitudes between 505 km and 521 km with an inclination of 35.0°. It travels at approximately 27,394 km/h (7.61 km/s), completing one full orbit every 95 minutes — that’s roughly 15.18 orbits per day. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks YAOGAN-39 05C in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
YAOGAN-39 05C orbits at an average altitude of 513 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 YAOGAN-39 05C’s average altitude, there are currently 8,917 active payloads and 266 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1184. This makes it one of the more crowded altitude bands, containing roughly 51.2% of all active satellites. With an inclination of 35.0°, YAOGAN-39 05C passes over latitudes between 35.0°N and 35.0°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. China operates approximately 1,219 active satellites in total, of which 217 share a similar altitude band with YAOGAN-39 05C.
🔗 Yaogan Reconnaissance Series
This satellite is part of China's Yaogan series, officially described as “remote sensing” satellites but widely assessed by analysts to serve military reconnaissance, signals intelligence and ocean surveillance missions. The series includes optical imaging, synthetic aperture radar (SAR) and electronic intelligence (ELINT) variants, some operating in coordinated orbital formations for persistent maritime monitoring.
