WorldView Legion

WorldView Legion is a six-satellite Earth observation constellation operated by Vantor, designed as a high-revisit successor to the earlier WorldView and GeoEye missions. The first pair (Legion 1 and Legion 2) launched in May 2024; the second and third pairs followed to build out the full six-satellite fleet. ^[1]

The constellation operates across two orbital planes. Legion 1 and Legion 2 fly in a near-polar orbit at approximately 515-524 km altitude and 97.58 degree inclination. ^{[2] [1]} Legion 3 through Legion 6 fly in a mid-inclination orbit at approximately 45 degree inclination and 507-530 km altitude. ^[1] The combination of orbital planes delivers sub-2-hour revisit over mid-latitude targets, with the operator quoting revisit times under two hours for tasked collection. ^[3]

Each satellite carries a pushbroom imaging payload (referred to as WorldView Legion Camera in eoPortal documentation; ^[3] WMO OSCAR records the instrument as Spaceview-NG for Legion-1 ^[2]) with a panchromatic GSD of 0.29 m per eoPortal ^[3] or 0.34 m per Satellite Imaging Corporation, ^[4] and a 9 km swath per eoPortal ^[3] or 10 km per Satellite Imaging Corporation. ^[4] The constellation supports tasked acquisitions and is the primary operational system in the Vantor portfolio as of 2025. ^[5]
