METHOD OF CORRECTION OF INERTIAL NAVIGATIONAL SYSTEM OF SPACE VEHICLE AT EXOATMOSPHERIC MOTION Russian patent published in 1996 - IPC

FIELD: correction of parameters of inertial navigational systems. SUBSTANCE: method consists in measuring linear relative parameters of at least one navigational satellite moving over known orbital trajectory, forming the correcting parameter vector by the data obtained, repeating operations at moments of time within preset correction interval and correcting the inertial navigational system by means of formed correcting parameters; in performing correction, apparent acceleration of space vehicle is created in preset fixed direction of inertial space; apparent acceleration thus created is measured at each moment TK which is stored and extended vector of correcting parameters is formed taking into account accelerations measured at moments TK-1 and TK. EFFECT: enhanced efficiency. 2 dwg
