Abstract

Dynamic Radio and Optical Astronomy instruments are becoming larger and more sophisticated, so they demand better, more precise control to enable the narrow field optics to perform their functions. Coaxing performance into the sub arcsecond region of pointing and tracking requires much more than just reducing friction and getting stronger gearboxes. It requires the designers to develop a fundamental feel of the structure's personality and its dynamic properties, the system nonlinearities, and macro- and microscopic aspects of the drive systems, bearings and other motion components of the instrument.
