«WinOrbit is a program for computing artificial Earth-satellite
position and visibility, with the Amateur Radio satellite
operator in mind. It was written for the Microsoft Windows 3.1
operating system.
WinOrbit has 4 basic functions:
* Graphical display of satellite positions in real-time,
simulation, and manual modes.
* Tabular display of satellite information in the same modes.
* Generation of tables (ephemerides ) of past or future
satellite information for planning or analysis of
satellite orbits.
* Output of current tracking information (az, el, doppler,
etc.) to a client program for control of tracking
hardware such as antennas, radios, or telescopes.»
