DESCRIPTION
The Antenna Control System Model No: PSES-ACS-001A used for tracking the Orbiting Satellites or LEO satellites in all the Earth Stations to receive the data continuously whenever the particular satellites passes its way from the view at an Earth station. Such Antenna Control Systems are used for moving object tracking like the Orbiting Satellites, Missiles, Aircrafts etc.
The Antenna Control Unit automatically adjusts its speed depending on the speed of movement of the Target. For such an application servo control mechanism is used. The Antenna Control unit consist of both Type-I and Type-II servo compensation technique to command the servo motors in both Azimuth and Elevation axis for achieving smooth movement so that the gearing mechanism is ensured of safety from any mechanical damages.
