FIELD: navigation.;SUBSTANCE: method of determining navigation parameters of a mobile object with compensation of random components of sensitive elements of a corrected inertial attitude and heading reference system, can be used in creation of inertial navigation systems for determination of navigation parameters of controlled mobile objects. Substance of the method consists in that, in addition to signals of integral and external correction of inertial attitude and heading reference system in composition of inertial navigation system, a correction signal is generated, which compensates for error in numbering ϕ and λ, from instability of parameters of sensitive elements of inertial attitude and heading reference system. Difference signal of linear velocity of object, obtained in inertial navigation system, and linear speed obtained by integration of external for inertial navigation system of navigation systems, is supplied to onboard computer unit materializing model of inertial attitude and heading reference system errors together with signals characterizing instability of parameters of sensitive elements.;EFFECT: high reliability of the correction system, reduced error in calculating geographical coordinates of the mobile object owing to compensation of parameters of instability of sensitive elements of the inertial attitude and heading reference system.;1 cl, 1 dwg, 1 tbl
