📖 About This Object
YAOGAN-33 03 is an active satellite operated by PLA Strategic Support Force (China), launched on 2023-09-06 from Jiuquan, China. It orbits in Low Earth Orbit (LEO) at altitudes between 692 km and 703 km with an inclination of 98.2°. It travels at approximately 27,034 km/h (7.51 km/s), completing one full orbit every 99 minutes — that’s roughly 14.59 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. 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 ~10–25 years. Orbital Radar tracks YAOGAN-33 03 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-33 03 orbits at an average altitude of 698 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of YAOGAN-33 03’s average altitude, there are currently 272 active payloads and 1,433 tracked debris or rocket body fragments — notable neighbours include TERRA, AQUA, LANDSAT 9. With an inclination of 98.2°, YAOGAN-33 03 passes over latitudes between 98.2°N and 98.2°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. China operates approximately 1,219 active satellites in total, of which 58 share a similar altitude band with YAOGAN-33 03.
🔗 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.
❓ Frequently Asked Questions
YAOGAN-33 03 is in a sun-synchronous orbit (SSO), a specialised form of LEO at approximately 698 km altitude. Its 98.2° inclination causes the orbital plane to precess at exactly the rate of the Earth’s revolution around the Sun, so the satellite crosses each latitude at a consistent local solar time. It completes one orbit every 99 minutes, travelling at 27,034 km/h.
YAOGAN-33 03 is operated by PLA Strategic Support Force (China). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 57797. You can track YAOGAN-33 03 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
YAOGAN-33 03 was launched on 2023-09-06 from Jiuquan, China, one of China’s oldest launch centres in the Gobi Desert, used for crewed Shenzhou missions and LEO satellites. At its current altitude, the estimated remaining orbital lifetime is: ~10–25 years. View the full satellite launch log.
Yes — Orbital Radar tracks YAOGAN-33 03 (NORAD ID 57797) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
YAOGAN-33 03 travels at approximately 27,034 km/h (16,798 mph) — roughly 7.51 km/s. It completes 14.59 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 29 sunrises and sunsets every 24 hours.
