OPTIMUM SIGNAL CONVERSION IN AN ASTROINERTIAL SYSTEM,
Abstract
The problem of continuous determination of the coordinate s(t), which is measured on the earth's surface along the arc of the great circle from point A to point B (where the object is located) is examined. A single-channel astro-inertial system is used. The principle of minimum error dispersions is used as the test of optimalness in solving the problem of synthesis of the dynamic characteristics of optimal conversion ensuring a minimal total error. Three limiting cases are examined: (1) the initial coordinate is known precisely and the mean velocity is known with low accuracy; (2) the initial coordinate is practically unknown and the mean velocity is known very accurately; (3) neither value is known. All of the results pertain to operating times of up to 1000 sec and on the order of tens and hundreds of hours.
