COMPLEX METHOD OF AIRCRAFT NAVIGATION Russian patent published in 2018 - IPC G01C21/00 G01S19/38 

FIELD: navigation.

SUBSTANCE: invention relates to the field of aircraft planes navigation using compound method of navigation, and also relates to the field of navigators for the control and management of aircraft planes. Complex method of aircraft navigation, functionally combining inertial method of navigation, satellite method of navigation and air-speed method of navigation using magnetometric sensors, in addition, an initial exhibition is held at the rate in the process of taxiing and rolling until the moment of detachment of the aircraft from the field auxiliary room (FAR), determination and swinging of the deviation of magnetometric sensors after drifting up by performing a flight in a circle, carry out the navigation process in three modes: basic mode of navigation, where the inertial system and the air data system (ADS) are corrected by the signals of the satellite navigation system (SNS), perform two-level control of the reliability of signals from the SNS receiver and determine the error in measuring airspeed and wind speed, using SNS signals, an alternative navigation mode, where the inertial system is corrected by the signals of the ADS, which is switched on in case of absence of signals from the SNS receivers or the reliability of signals from the SNS receiver and the reversion navigation, which is switched on in case of a failure of the SNS and ADS, where an adapting to resenting reversion system for determining the attitude angle is used, signal-corrected accelerometers and magnetometric sensors with charged off deviation during flight, they optimize the coefficients of adaptive correction of angles according to the accelerometer signals, depending on the flight mode of the aircraft.

EFFECT: technical result is enhanced functionality, increased reliability and efficiency of navigation, as well as improving the accuracy of determining navigation parameters in case of loss of signals from the satellite navigation system receiver (SNS).
