METHOD FOR INCREASING THE NOISE IMMUNITY OF GUIDED AMMUNITIONS BY NAVIGATION SIGNALS Russian patent published in 2021 - IPC F41G7/22 F42B15/01 G05D1/00 

FIELD: military technology.

SUBSTANCE: invention relates to the field of fire damage to objects and can be used in high-precision complexes that use global satellite navigation systems at various stages of guided ammunition guidance (GA). The coordinates of the target location are determined and their values are entered in the GA. The area of possible coordinates of the spatial position of the GA is determined at the flight distance from the launch vehicle to the target. Their values are entered in the GA and it is launched. Navigation signals are received at the i-th points of time of the GA. Their parameters are measured and the i-th coordinates of the spatial position of the GA are determined by their values. It is determined whether the i-th coordinates of the GA position belong to the area of possible coordinates of the GA position. The flight path of the GA is adjusted relative to the i-th coordinates of the position to the coordinates of the target location if the i-th coordinates of the GA position belong to the area of possible coordinates of the GA position. The flight of the GA is carried out without adjusting the trajectory to the coordinates of the target location if the i-th coordinates of the GA position do not belong to the area of possible coordinates of the GA position.

EFFECT: noise immunity increases.
