WorldView-1

WorldView-1 is a panchromatic-only commercial Earth observation satellite launched on 18 September 2007. ^[1] Operated by Vantor (formerly Maxar Intelligence, rebranded October 2025), ^[2] it was one of the first commercial satellites to offer sub-half-metre imagery at scale. The satellite carries a single panchromatic sensor with a 17.9 km swath. ^[3]

The satellite's orbit was lowered and its local time of descending node shifted in June 2016 after an 18-month transition. Current orbital parameters per WMO OSCAR (February 2026) are a Sun-synchronous orbit at 499 km altitude, 97.87 degree inclination, and 13:30 LTDN. ^[3] Earlier sources including eoPortal and ESA EO Gateway record the pre-2016 values of 496 km and 10:30 LTDN and are stale for current characterisation. ^{[1] [4]} At its current altitude, the satellite achieves a revisit interval of approximately 1.7 days. ^[3] The satellite was in an extended operational phase as of February 2026; no decommission date had been announced, though Vantor's WorldView Legion constellation is expected to succeed the earlier WorldView and GeoEye missions. ^[5] The archive extends approximately 18 years. ^[5]
