NAVIGATION METHOD OF MOVING OBJECTS Russian patent published in 2011 - IPC G01C21/20 

FIELD: instrument making.

SUBSTANCE: first, on the basis of use of multibeam measurements, position of object is determined without obtaining correction signal of trajectory of its movement with connection to coordinate grid joints. Then, location of moving objects is specified by using the measurement mode with installation of new uncertainty quadrates on reference map. Sizes of quadrates on map are determined with correction signal error of movement trajectory with connection to coordinate grid joints, and their number - with the number of beams of multibeam measurements. At that, intervals of measurement pitches and the appropriate coordinate grids are chosen without increasing the volume of stored priori information on moving object and volume of made calculations.

EFFECT: accuracy improvement.
