AvL Cable Drive Positioner
The most important of specifications for a satellite antenna is the pointing accuracy and the stability of the positioner under the most extreme environmental conditions.
AvL's patent-pending Zero Backlash AvL Cable Drive technology provides the ultimate in precision and stiffness over geared or other drive systems.
The AvL Cable Drive rotary drive system suffers no backlash and is a simple maintainence-free dry mechanism able to operate in a very wide range of difficult and hazardous conditions without degradation.
The AvL Cable Drive technology is an elegant, simple, system that utilizes the averaging effect of many cables wrapped around a drive capstan and an output shaft.
The most important of specifications for a satellite antenna, particularly an auto-acquisition antenna, is the pointing accuracy and the stability and stiffness of the positioner under the most extreme environmental conditions. The positioning accuracy is determined by how precisely the positioner can move to a defined point as well as how stable and stiff the positioner is in maintaining that position. The speed of movement is based on how quickly the positioner can move to a defined position.
