AvL antenna systems combine the AvL Cable Drive positioning system with a completely automatic
satellite acquisition Antenna Control Unit (ACU) to provide ease of operation without needing a satellite
technician and the ultimate in reliability under even the most demanding environmental conditions.
Our latest line of antenna systems features our AAQ ACU. The AAQ ACU is a robust system offering a
variety of software control functions, high speed sensors, and High-Level integration between hardware
and software. This new system is designed for complete integration into new or existing AvL antenna
systems.
