INERTIAL NAVIGATION SYSTEM Russian patent published in 2002 - IPC

FIELD: navigation systems. SUBSTANCE: given inertial navigation system is intended for use of various vehicles, such as sea vessels, aircraft, motor vehicles, etc integrated with other device generating navigational information. System includes platform in gimbal suspension, gyroscopes, accelerometers, meter measuring motion parameters coupled to input of Kalman filter. Device generating discrete correction signal comprising unit forming matrix of control influence, unit forming transitory matrix of control, unit cutting off matrixes, multiplier, inverter, unit forming summary control, unit limiting and controlling permissible load of control and unit filing control is inserted between control inputs of gyroscopes , inputs of adders and inputs of zero drift of accelerometers and outputs of Kalman filter. EFFECT: increased operational precision of system, minimized time for system setting out. 3 dwg
