Earth-Observation Sats, decoded.
Who watches Earth, at what resolution and revisit.
CURATED INDEX◊ confidence: High
// the signal · what the data says
Earth observation splits between very-high-resolution optical (Maxar, Airbus, ~30cm), high-revisit smallsat fleets (Planet, daily global), and all-weather radar (ICEYE, Capella SAR). NASA-ISRO's NISAR (2025) added dual-band L/S radar for global deformation monitoring on a 12-day repeat.
