What does a sun-synchronous orbit guarantee?
Plain English (default view) — short, conversational, lightly seasoned with science
🔬 Scientific / formula (revealed on click) — markdown + $$…$$ ok
A near-polar orbit tuned so the orbital plane **precesses at Earth's orbital rate** around the Sun. - 🛰️ **Result:** satellite crosses the equator at the **same local solar time every day** (typically 9:30 – 10:00 AM) - 🌅 **Why it matters:** consistent sun angle → comparable imagery across dates - 📷 **Used by:** Landsat, SPOT, IKONOS, Sentinel-2 — basically every Earth-observing land sensor
