ADVANTAGES

A POES satellite can hover over one polar area a large part of the time, albeit at a large distance, using a polar highly elliptical orbit with its apogee above that area. This is the principle behind a Molniya orbit used for earth-mapping, earth observation; and reconnaissance satellites, as well as some weather satellites

Geostationary satellites have revolutionized global communications, television broadcasting and weather forecasting, and have a number of important defense and intelligence applications
