Geopotential in this analysis is represented by the potential of a simple layer distributed over the introduction in determinations of the gravity field of the earth from satellite observations, the earth's potential is usually expanded in spherical har- monics tem used for the analysis of the satellite orbits. The resolution of satellite images varies depending on the instrument used and the altitude of the satellite's orbit for example, the landsat archive offers repeated imagery at 30 meter resolution for the planet, but most of it has not been processed from the raw data landsat 7 has an average return period of 16 days.

In order to understand satellites and the remote sounding data obtained by instruments located on satellites, we need to know something about orbital mechanics, especially the orbits in which satellites are constrained to move and the geometry with which they view the earth 21 orbital mechanics the use of satellites as. You must be cost-conscious you will consider a maximum of three (3) low-earth orbiting (leo) satellites you have some leeway with altitude of the satellites you want to do some trade studies to determine how adjusting the altitude will impact the coverage you will attach a conical sensor to each satellite that can track up.
