AC3000E Antenna Control System is a set of antenna pointing control system with perfect function, it can manual or automatic control the antenna position pointing to the peak value of the receipt signal from the synchronous communication satellite. AC3000E antenna control system is designed with the latest digital processing technology, with the precise antenna pointing, high reliability and maximum flexibility in system configuration. The system has a storage capacity of multiple satellites, practical inclined orbit tracking capability , with input of RS-322, RS-422 or RS-485 remote control communication (Ethernet is optional). In addition, it is designed with the lightning protection to ensure stable system and reliable operation. AC3000E antenna control system can work well for various antenna control with the antenna of diameter below 10 meter.
The port connecting the AC3000E antenna control system and the tracking signal is serial port, any DC voltage of -5~+5V(Including satellite receiver AGC output, MODELDC output etc.
