METHOD OF MEASURING MAGNETIC HEADING OF MOBILE OBJECT Russian patent published in 1999 - IPC

FIELD: navigational instrumentation engineering; measuring magnetic heading and angles of inclination of mobile objects. SUBSTANCE: for measuring the magnetic heading use is made of information on Earth's magnetic field vectors and linear acceleration of mobile object. calculation of one of angles on inclination of mobile object required for determination of magnetic heading is effected from equality of a priori known horizontal or vertical component of Earth's magnetic field intensity with calculated magnitude by information measured by means of sensors. Calculation of other angle of inclination is effected by information measured by means of sensor and first angle of inclination determined as described above. EFFECT: enhanced accuracy of measurements irrespective of mode of motion of abject. 1 dwg
