Hint - Geosynchronous Satellites.
Satellites which orbit the earth in exactly one solar day, are
geosynchronous. If the inclination is zero, and the eccentricity is
zero, the satellite will appear fixed in the sky over a particular point on the
equator. Such satellites, often used for commercial communication, are often
described, not by a full
Keplerian Element Set,
but simply by their longitude.
To track such a satellite with WinOrbit, all you need is this longitude.
Satellite Information Window,
click Edit Elements, then select
You'll be prompted for the longitude. It's best to use the Ideal orbital
model for these, otherwise the position will drift slowly (these satellites
have to use fuel to adjust their orbits).
