Flyby is a console based satellite tracking program that can track a satellite across the sky with an antenna and adjust your radio with uplink and downlink frequency doppler shift.
Satellite orbit parameters are given as NORAD two-line element sets (TLEs). You can use any rotator controller and radio supported by hamlib.
This is free and open source software.
