Hint - Evaluate Special Orbits.
Certain values of inclination, mean motion and eccentricity lead to
interesting effects. For example, proper choice of the inclination can lead to
a sun-synchronous orbit, which passes over a given spot at exactly the same
local time each day. Other values will inhibit the precession of the orbit, so
that the satellite position will repeat every year. And so on. One way to
investigate this, is to use the
Satellite Information Window
Edit option, enter a set of elements, and a new epoch (for example the
same time of day, but 1 day week, or year later). Then choose
Special:Propagate Elements to Epoch
to calculate the new elements. Note the longitude of the node (position on
earth) and the Right Ascencion of the node (position in space). Also the
Argument of Perigee (related to the latitude of perigee) is interesting.
