| description | FIELD: initial alignment of inertial navigational systems. SUBSTANCE: gyro- stabilized platform of inertial navigational system is immovably stabilized relative to inertial coordinate system. Signal from accelerometers are measured at initial period of time and measurement is repeated after small interval. Elements of matrix of direction cosines are calculated between inertial and normal coordinate systems. On base of elements of matrix of direction cosines thus calculated orientation of inertial coordinate system connected with gyrostabilized platform is determined relative to normal coordinate system. EFFECT: enhanced accuracy; reduced duration of alignment procedure. |
