A STUDY OF THE EFFECT OF ERRORS IN MEASUREMENT OF VELOCITY AND FLIGHT-PATH ANGLE ON THE GUIDANCE OF A SPACE VEHICLE APPROACHING THE EARTH

Abstract

A study was made to determine the effect of errors in measuring velocity and flight-path angle, in applying the corrective thrust, and in the initial predicted perigee altitude upon the guidance of a space vehicle to a desired perigee altitude. Corrective impulses were applied only when the vehicle's predicted perigee altitude was not within a deadband about the desired perigee altitude. The method of scheduling observation points along the trajectory was to make an observation (and to apply a correction if needed) each time the true anomaly increased a given amount. (Author)
