Track Software is available for EME (Moonbounce), Radio Astronomy and Satellite Tracking applications and lot more.

Most used is PstRotator - Universal Track software, for Azimuth and Elevation, shareware
(PST rotor can be used as a step-up for track software that does not directly support the SPID protocol Rot2Prog)

*Note: All SPID rotators are able to emulate Hy-Gain, Yaesu and Orion control units, is it compatible to almost any software.
(Note: In Emulation modes only the most basic commands can be used)
