GDSatcom 7200/7205 Antenna Controller with 18-bits digital encoders

Condition:Used and tested
Manufacturer:GDSatcom Technologies

GD Satcom 7200/7205 Antenna Controller, 3-Axis, IDU with 18-bit digital encoders for motorized Earth Station Antennas

The GD Satcom Model 7200/7205 Antenna Control System is a state-of-the-art automatic positioning system which incorporates advanced control modes and an enhanced menu-driven user interface to provide accurate antenna positioning with minimum operator effort. Fully automatic tracking of inclined orbit satellites is accomplished with the revolutionary GD Satcom Orbit Prediction Track (OPT) algorithm, which generates future AZ and EL pointing data by propagating a physically valid orbit through initial measured data to the time of interest. This type of ephemeris prediction offers increased efficiency and accuracy over methods which merely use measured data in a curve fitting routine to predict a trajectory.

The GD Satcom 7200/7205 Antenna Controller user interface employs a front panel graphics display which provides convenient menu-driven editing and control function selection. In addition, a “Target- Oriented” operating environment allows the system to have custom-configured control modes for multiple satellites, with simultaneous maintenance of corresponding data bases for each. The system is configured around the Model 7200/7205 Antenna Control Unit (ACU), contained in a 7-inch rack-mountable cabinet.

The system is controllable via RS-232C or RS-422 serial ports, allowing for remote operation or integration with a supervisory monitor and control computer.
