What is the advantage of Geosynchronous Earth Orbit?

• A. Continuous coverage over a specific area
• B. Global, real-time coverage of all Earth regions
• C. Proximity to Earth for high-resolution imaging
• D. Lower latency than LEO

Answer: (A)

Geosynchronous orbit has an orbital period that matches Earth's rotation, so the satellite stays over roughly the same area on the surface. When the orbit is aligned with the equator (geostationary), it appears fixed in the sky to observers at that longitude. This makes it possible to provide continuous, uninterrupted coverage over a particular region for long periods, which is ideal for communications relays and weather observation of that area. That fixed-area advantage isn’t global real-time coverage—one GEO satellite can’t see all regions at once, and viewing becomes limited toward higher latitudes. Also, being far from Earth means imaging is not high-resolution compared to closer, low-Earth-orbit satellites, and the signal latency is higher than from a nearer satellite.
