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. In the Satellite Information Window, click Edit Elements, then select Special:Make Geosynchronous. 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).
