AvL antenna systems combine the patented AvL Cable Drive positioning system with totally automatic satellite acquisition to provide ease of operation (without a satellite technician) and ultimate reliability under even the most demanding environmental conditions. Our auto-acquisition controllers contain embedded software (no software to install!) to automatically find the satellite in minutes providing rapid deployment and operation on any satellite worldwide. Compatible with every satellite modem without modem interface required, the controllers have integrated GPS to determine exact site location, compass, base level sensors, and a receiver that allows satellite acquisition and optimum peaking and cross pol nulling without any connection to the RF system resulting in automatic optimization of azimuth and elevation and polarization alignment. Safety features include shut off of receive link if movement is detected and a stow command if the vehicle moves or tilt sensors are activated.
