FIELD: physics. ^ SUBSTANCE: control values of absolute pressure, control values of projections of the resultant magnetic field intensity vector of the Earth and the magnetic field of the object, the projections of gravitational acceleration and the projections of angular velocity vectors on orthogonal axes of the navigation coordinate system are measured. Spatial coordinates of the mobile object are corrected and filtered based on the obtained values. In order to realise the method, the system has digital sensor units for linear acceleration (1), magnetic field (2), gyroscopes (3), absolute pressure (4), temperature (5), reckoning (6), time storage (7), a satellite radio navigation system receiver (8), a touch display (9), a modem (10) and a computer module (11). ^ EFFECT: high-precision determination of spatial coordinates with possibility of monitoring. ^ 12 cl, 6 dwg |
