METHOD OF INCREASING GUIDANCE ACCURACY OF DEVELOPMENT STEPS FOR VARIOUS PURPOSES Russian patent published in 2012 - IPC G01C21/24 

FIELD: physics.

SUBSTANCE: spatial correcting effects are generated during movement of DS in a plane close to the "plane of the ballistic horizon". Generation of correcting effects is carried out on intervals for determining the initial orientation of the instrument coordinate system relative the base coordinate system. Vector matching of the coordinate for guiding the DS to the target is used. Each step for correcting the transition matrix from the instrument coordinate system to the base coordinate system increases accuracy of its determination, thus ensuring high accuracy of guiding final stages to the target.

EFFECT: high accuracy.
