METHOD FOR TESTING THE BEHAVIOUR OF UAVs UNDER CONDITIONS OF DISTORTION OR SUPPRESSION OF THE NAVIGATION FIELD OF A SATELLITE NAVIGATION SYSTEM Russian patent published in 2021 - IPC G06F11/36 

FIELD: aircrafts.

SUBSTANCE: invention relates to unmanned aerial vehicles, specifically to the field of software and hardware testing of the behaviour of UAVs under conditions of distortion or suppression of the navigation field. The method for testing the behaviour of UAVs under conditions of distortion or suppression of the navigation field of the SNS consists of several stages. Receiving the data on the location and parameters of the navigation field by a GNSS receiver operating in the normal mode. The data on the distance from the start point and speeds in the reference coordinate system are then received from the navigation data modelling software module of the GNSS receiver. Data packets are then formed in the reference coordinate system by the navigation data modelling software module of the GNSS receiver based on the data received from the simulation model. The accuracy parameters of the navigation signal therein remain preset by default. The deviations of the received coordinates from certain initial values obtained prior to activating the simulation model by averaging over a certain interval of time. A navigation solution is then formed by the navigation data modelling software module of the GNSS receiver for the simulation model (parameters with the control index), calculated based on the data received from the simulation model (parameters with the model index) with added deviations of the parameters calculated at the previous stage. The speed relative to the Earth is then calculated.

EFFECT: reduction in the probability of occurrence of emergency situations caused by abnormal operation of the automatic equipment under conditions of distortion or suppression of the navigation field.
