Doppler compensation using GPredict and RigCtlD

It is difficult to work on satellites without using Doppler effect compensation. After all, during a flight, the reception frequency changes, especially quickly in the middle of the orbit.

There are two ways to compensate for frequency changes due to the Doppler effect - manually, using two independent transceivers (or one with Duplex function) and automatically using programs such as GPredict, SATPC32 or Orbitron.

In this article I will try to set up automatic correction of transmitting and receiving frequencies in Linux.
