METHOD OF POSITIONING THE OBJECT OF THE CROSSING DISTANCE AND ANGLE OF THE SITE FROM THE FIRST MEASURING ITEM AND THE ANGLE OF THE SITE - WITH THE SECOND Russian patent published in 2019 - IPC G01S5/02 

FIELD: measurement technology.

SUBSTANCE: invention relates to the field of determining the coordinates of aircraft for various purposes and can be used in military equipment. On the first and second measuring points measure the distance and elevation angles R₁,ε₁,ε₂, where the indices denote the number of the measuring point with the corresponding coordinates (X_G1; h_G1; Y_G1), (X_G2; h_G2; Y_G2), convert the measured values into rectangular coordinates of the measurement object (X_GO; h_GO, Y_GO), at the same time the measured value R₁=const geometrically defines a sphere of radius R₁ centered on the first measuring point measured value ε₁ defines a straight circular cone with a vertical axis of symmetry, half-angle of 90°-ε₁ and vertex in the first measuring point, the measured value ε₂ defines a straight circular cone with a vertical axis of symmetry, half-angle of 90°-ε₂ and the top of the second measuring point, performs processing of external trajectory information by solving a geometric problem of intersection of a right circular cone and a sphere centered at the first measuring point and a right circular cone with its top in the second measuring point, the intersection points of the specified geometric figures determine the position of the measurement object, moreover, the algebraic solution of a geometric problem is reduced to finding the roots of a system of two quadratic equations describing two circles belonging to the horizontal plane

with the subsequent definition of aircraft applicants according to h_GO=h_G1+R₁sin ε₁.

EFFECT: development of a method for determining the coordinates of aircraft in the presence of the minimum necessary amount of information, as well as an assessment of the accuracy of the positioning of the object.
