METHODS OF GENERATING DATA ON THE ORIENTATION OF THE OBJECT AND THE NAVIGATION SYSTEM OF THE AIRCRAFT FOR THEIR IMPLEMENTATION Russian patent published in 2021 - IPC G01C23/00 

FIELD: orientation systems of the aircraft.

SUBSTANCE: claimed methods of generating data on the orientation of the aircraft and the navigation system of the aircraft relate to the field of orientation systems of aircraft (hereinafter – A), mainly unmanned A of airplane type and A of small aviation. The essence of this technical solution is that the first method to generate data about the orientation of A use measurements of installed on A three accelerometers, three gyro sensors of angular speeds, three-axis magnetometer, axes of which are parallel to axes of the A - X, Y, Z, airspeed sensor and angle of deviation of the pendulum system, the swing axis which is parallel to transverse axis (Z) of the associated coordinate system of the A. In the second method, in the process of smoothing the obtained orientation angles, angular speeds are used, recalculated into the coordinate system in which the orientation angles are measured. The third method uses the speed obtained, for example, on the basis of a flight task (setting the speed programmatically). In the fourth method, both the program value of the A speed is used to form the orientation angles, and the values of the angular speeds converted into the coordinate system in which the orientation angles are measured, to smooth out the obtained orientation angles. These methods are implemented using the navigation system of the A, which contains: a computer, an accelerometer, a gyro sensor of angular speeds, a pendulum system consisting of a pendulum that is equipped with a swing angle sensor, and an airspeed sensor.

EFFECT: technical result is to ensure the autonomous functioning of the aircraft navigation system during the flight.
