Scientific paper

A microcircuit-based control device is described in which the moments of observation-cycle commencement and cycle types for 256 stars are programmed. The duration of the exposure is set automatically depending on the type of cycle. This device simplifies the work of the observer and leads to an improved accuracy of latitude measurement and an improved time correction.
