BASIC Theory of Operation
Antenna Description
 Three axis, polarization over elevation over azimuth
 Configurable for operation on most satellites
 Designed for simple operation, performs precise
antenna to satellite alignment with the push of a
button or a switch
 Pedestal Description:
 High precision motors with optical encoders
 Very low backlash drive system
 Each antenna is fully integrated with
 GPS
 Compass
 DVB Receiver
 Base level sensor
 Antenna Control System with User Interface
The Standard Satellite Acquisition Process
Upon power up and deployment, the following
acquisition sequence takes place:
 Compass aligns the antenna with south (if in the
northern hemisphere, to the north if in the
southern hemisphere)
 Antenna acquires GPS for high precision
geographic location information
 Antenna precisely sets elevation angle and
sweeps through a selected reference satellite,
monitoring signal characteristics of the reference
satellite
 Antenna peaks on reference satellite until the
center of the antenna beam is located as an
alignment reference. Antenna then peaks on the
satellite of interest and performs a high precision
alignment to the satellite
 Antenna sends GPS to satellite modem (if
applicable)
 Satellite modem initiates contact with network
operations center
