• 🪞 Steerable mirror tilts up to ±27° from vertical
• 📐 Stereoscopic imagery — two views from different angles → parallax → 3D / DEMs
• ⏱️ Revisit boost — 26-day nadir cycle → 1–5 days at mid-latitudes
• 🌍 Swath access — can image ~900 km on either side of the ground track

IKONOS does the same but with a wider tilt range (±45°).
