METHOD FOR CONTROLLING THE DATA RELIABILITY OF AUTOMATIC DEPENDENT SURVEILLANCE SYSTEM Russian patent published in 2018 - IPC G01S13/74 G08G5/02 

FIELD: navigation system.

SUBSTANCE: invention relates to the field of aircraft navigation (AC), is intended to ensure the safety of aircraft flying by using an automatic dependent surveillance (ADS) system on board of an aircraft. Increase in the reliability of the ADS data is achieved by the fact that joint use of the ADS system and the satellite navigation system (SNS) is provided, the reception of SNS signals and definition of coordinates and a vector of speed of the aircraft, the reception of ADS signals and determination of coordinates of adjacent aircrafts, the calculation of the distances of adjacent aircrafts by certain coordinates, the formation of a time scale and the distance measurement of adjacent aircrafts by the delay time of the ADS signals, the comparison of the difference of said calculated and measured distances with a preset threshold, in case of exceeding the specified difference in the preset threshold, an invalid signal of ADS data and an invalid signal is displayed on the air situation display, in accordance with the said time scale, ADS signals are generated and their radiation is carried out, then dangerous trajectories of adjacent aircrafts are detected, a modulation signal is generated and by the means of this signal modulation of the coordinates of its aircraft is made, the modulation signal in the coordinates of adjacent aircrafts on dangerous trajectories is performed, and if such modulation is detected, an additional signal of unauthenticity of the ADS data is generated and an additional invalid signal is displayed in the air situation display.

EFFECT: achieved technical result is the increase in noise immunity of the ADS system on the basis of increasing the reliability of its data.
