The remote sensing satellite earth station is composed by antenna, feed subsystem , servo subsystem, receiver, station manage subsystem, modulator, demodulator, recorder and quick view equipment.
The performance of servo control system determines the reliability and stability of VTR (video Tape Recorder), and enables ultimately VTRs to record and replay video signal accurately.
