MORE PRECISE POSITIONING IN UNDERWATER NAVIGATION SPACE FORMED BY RANDOMLY ARRANGED HYDROACOUSTIC TRANSPONDER BEACONS

摘要

FIELD: physics.SUBSTANCE: result is achieved by integrating inertial, hydroacoustic, hydrostatic and magnetic measurements via digital statistical optimum processing of an excess number of measurements of parameters of movement and positioning of the object to estimate instrument errors, consistence of which is based on equally accurate hydroacoustic measurements for determining global coordinates of hydroacoustic transponder beacons as the positioning object moves from the point of inputting initial values of global coordinates and then determining more precise spatial global coordinates of the positioning object and orientation angles thereof.EFFECT: high accuracy of positioning on coordinates and orientation angles.2 cl, 1 dwg, 1 tbl
