Paper Abstract

Designing an installation of a high resolution encoder (19 to 22 bits) on a radar or optical tracker is a technically demanding job. Unfortunately, many designers treat the installation planning of an encoder as a simple bolt-on job and frequently not enough space is left, or mounting surfaces are provided which are not commensurate with the accuracy of the encoder. A further complicating factor is that many encoders must be mounted on structures that were not originally designed to accept a transducer of such high resolution and accuracy. A poor installation causes a tracking error between the system's boresight axis (optical or radar) and the encoder readout angle. This paper will present a thorough review of the mechanical parameters that must be defined and controlled to properly interface a high resolution encoder. The paper will also discuss maintenance techniques that can be used to lower operating costs and improve operating reliability over the life of the equipment.
