FIELD: inertial navigation, specifically determination of present values of coordinates of moving object. SUBSTANCE: increased accuracy of inertial navigation is achieved thanks to determination of angular drift of reading coordinate system of navigational system which operational mode corresponds to standard model. Relative angular mismatch of reading coordinate system and nominal reading coordinate system is determined by comparison of real signals from accelerometers of navigational system with signals of accelerometers computed on basis of usage of intermediate and output parameters of standard model of navigational system re-calculated into output signals from accelerometers corresponding to them using functional realization of standard model for reverse re-calculation of its output parameters to input ones corresponding to them. Reading coordinate system of standard model is turned with reference to reading coordinate system of navigational system through angles fixed in space. EFFECT: increased accuracy of determination of present coordinates of moving object. |
