WORLDVIEW 1

WORLDVIEW 1 is an active satellite operated by Maxar Technologies Inc. (United States), launched on 2007-09-18 from Vandenberg SFB, California. After 19 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Low Earth Orbit (LEO) at altitudes between 492 km and 494 km with an inclination of 97.4°. It travels at approximately 27,434 km/h (7.62 km/s), completing one full orbit every 94 minutes — that’s roughly 15.24 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 ~1–3 years. Orbital Radar tracks WORLDVIEW 1 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

WORLDVIEW 1 orbits at an average altitude of 493 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 WORLDVIEW 1’s average altitude, there are currently 9,166 active payloads and 239 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1047. This makes it one of the more crowded altitude bands, containing roughly 52.6% of all active satellites. With an inclination of 97.4°, WORLDVIEW 1 passes over latitudes between 97.4°N and 97.4°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. United States operates approximately 12,360 active satellites in total, of which 8,563 share a similar altitude band with WORLDVIEW 1.
