METHOD OF DETERMINING AMMUNITION DROP POINTS Russian patent published in 2019 - IPC F41J5/00 

FIELD: test technology.

SUBSTANCE: invention relates to testing fire complexes and can be used to determine a priori accuracy of their firing using a sea target position. To determine points of falling of ammunition, direction-finder is used to measure bearing angles to a flying ammunition in the area of design point of its fall. A trajectory of the ammunition and its drop point are determined on coordinates of points of intersection of bearing lines. Direction finders are placed on unmanned aerial vehicles (2) which, prior to design time of ammunition delivery, are lifted on cable-ties (3) to spaced points of space above sea target position (1), which is preliminary delivered to area of design point of falling of ammunition (5) and coordinates of which are refined using global navigation system. Results of measurement of bearings angles to flying ammunition (5) in area of design point of its falling from each of unmanned aerial vehicles (2) and determination of trajectory of flight of ammunition (5) and its fall point along coordinates of points of intersection of bearing lines is carried out on processing and control facility (4), arranged on sea target position (1), where measurement results are sent via cable-leashes (3), which are used for force retention of unmanned aerial vehicles (2) and transmission of control signals to their board.

EFFECT: determining coordinates of points of falling of ammunition in the process of tests with a priori evaluation of errors of their delivery during firing at sea targets, including ammunitions which are low above sea surface.
