METHOD OF PERFORMING OF DEVIATION OPERATIONS ON MOVING OBJECTS

摘要

FIELD: navigation; geomagnetic measurements. SUBSTANCE: prestarting measurements of longitudinal, lateral and normal components of intensity vector of object resultant magnetic field are performed by means of airborne magnetometer in object resultant magnetic field are performed by means of airborne magnetometer in object heading position. Values of longitudinal, lateral and normal components of object resultant magnetic field are measured additionally by at least six gimballess three-component magnetometers. Their corresponding sensitivity axes are parallel, and spaces between them are fixed. Angles of gyroscopic heading, pitch and roll are measured on area with known horizontal and vertical components of geomagnetic field. Measured values are converted to parameters of equivalent source of object magnetic interferences, with due regard for which value of angle of moving object magnetic heading is found in process of motion. Magnetometers are positioned in one plane and in one straight line on removable nonmagnetic rack provided with turning angle- measuring scale. EFFECT: higher measurement results. 5 dwg
