DESCRIPTION
The Geo Stationary Antenna Control System is used to track and maintain its peak value for all the geostationary satellites so that communication link  is available at all times.
In Such Control Systems the Antenna Control Unit controls the movement of the Antenna and maintains its position on the Peak signal Strength. This function is called as Step Track. This will be performed at specific intervals so that it ensures the link availability even under low signal level conditions.
