Examples of several types of orbits.The Earth’s center of mass must be in the orbital plane – so Geostationary orbitsmust be in the Equatorial plane. Low Earth Orbits are inclined from theequatorial plane. Specialized orbits are used for different purposes.• Sun-synchronous orbits cross the equator at the same time each solar day.• Low inclination orbits are used to look more closely at tropical processes.• Exact-repeat orbits fill in a grid of orbit tracks over X days, then repeat exactly.
A Global System of Geosynchronous <strong>Satellite</strong>sGeostationary Sampling: Easy to picture – a sequence ofimages/fields from a fixed viewing geometry. Five satellites coverthe globe, maintained by nations that need the data. The first“weather satellites” were essentially TV cameras in space. For thefirst time, we could see distant storms developing andapproaching. The very first satellites carried film cameras andwere not looking at weather. How did the film get to earth?
