Abstract : Computer errors are essentially random in character, and the authors discuss them from the point of view of the theory of random processes. For the control of information processed by computers, they propose program logic control based on the redundancy of the original and intermediate information. This differs from other cases encountered in various branches of technology where the computer control may be based on comparisons with appropriate standards. The redundancy leads to various control relationships connecting the calculated quantities which may then be verified at the end of each computational cycle. The computer self-control is applied to the specific case of telescope control. A complete block diagram is given of the program logic and test control appropriate for this type of azimuthal rotation control.
