Question

What is the main advantage of LEO satellite constellations (like Starlink) over single GEO satellites?
  1. A
    Higher bandwidth per satellite
  2. B
    Much lower latency and better coverage at polar regions
    Correct
  3. C
    Simpler ground equipment
  4. D
    No need for orbital corrections

Correct answer

Much lower latency and better coverage at polar regions

Explanation

GEO: 36,000 km altitude, ~250 ms delay, cannot see poles (>75° latitude). LEO: 500–1200 km, ~5–15 ms delay, polar coverage, but needs 500–12,000+ satellites for global coverage. Starlink (SpaceX) has ~5,000 operational satellites at ~550 km.
