Analysis of instrumental errors influence on the accuracy of instruments for measuring parameters of moving objects

This paper presents the results of the analysis of the influence of instrumental and methodical errors on the accuracy of instruments for measuring parameters of moving objects. The analysis is based on a new method for examining those errors which allows the static measurement mode to be considered as a separate measuring procedure. Based on that method there have been derived mathematical models for determining and investigating the probabilistic characteristics of the instrumental error of measuring instruments, whose output signal is quantized in value. In addition, the paper presents the results from experimental investigation of the methodical and instrumental components of an instrument for measuring ship pitch.
