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
