Intellian Antenna Control Unit: Central Hub for Satellite Antenna Management

The ACU is part of a larger satellite communication system created and manufactured by Intellian. It is essentially a control unit that is central to managing a satellite dish antenna’s movement and optimization, especially when used with VSAT communication solutions and satellite television.

Essentially, at its heart, it is about interpreting sensor information on a ship, including gyro and GPS systems, and determining behavior of the satellite dish as it maintains its position with respect to a desired satellite. This is particularly important on platforms that are in motion, with constant pitch and roll movements.

Generally speaking, Intellian brand ACUs tend to have user interfaces that allow network parameters to be set/changed by the technician. They also tend to be interfaced with the display units/chart plotters through Ethernet connections or the NMEA interface. These allow communication between the navigation systems, VSAT modems/routers, etc., and the antenna itself.

To briefly conclude, it is to be understood that the Intellian antenna control unit is primarily responsible for being the ‘brain’ of the antenna systems in order to maintain stable and efficient connections to various satellite systems for broadband, TV, and voice connections—especially when it comes to sea-based systems or vessels in particular.
