AvL Cable Drive Positioner
AvL's patented AvL Cable Drive rotary 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 rotary 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.
