A variety of positioner control systems are available for making antenna and RCS measurements, but few can be upgraded economically as test facilities are expanded. Positioner control system components may include a controller, positioner motor drive unit, and a position indicator. Integration of these functional components into a single modular unit to operate the desired number of axes provides the basis for a positioner control system. Other desired features may include programmability, remotability, operation outdoors, and expansion capability.

This paper will address the development of a modular positioner control system that provides users with a basic system that can economically be upgraded as changing test requirements dictate. Functional capabilities such as remotability will be highlighted. System configuration and integration will also be discussed.
