Abstract
The problem of determining the position continues to be the most important problem of geodesy. With the development of measuring instruments and techniques, the widespread use of electronic distance meters, the precise and rapid computation possibilities provided by artificial ground satellites and computers, the segmented approach in the positioning problem (separate calculation of horizontal and vertical coordinates) has left the place as an integrated approach, dimensional coordinates have begun to be calculated together. It is possible to determine the 3D coordinates of the station point with only 3 zenith (vertical) angles. The problem of position determination is done either in the form of basic homework or (usually) predictions. It is also possible to calculate the three-dimensional coordinates of the points by the proposed resection method.

Summary
The problem of geodesic positioning problem was resolved separately as horizontal positioning and vertical positioning. It is possible to solve this problem by taking advantage of the measured zenith angles. In this case, the problem is referred to as space resection. The problem is referred to as space resection In this method, the three-dimensional coordinates are to be calculated between point P and at least three points such as A(ya,xa,za), B(yb,xb,zb) ve C(yc,xc,zc) the 3D coordinates of the P (yp,xp,zp) point can be calculated by the , , zenith angles measure [5]. The approximate values yo,xo,zo of the unknowns (coordinates of the point P) are selected. Three zenith angles measures are sufficient to allow the algebraic solution to be performed without space resection. The height of the instrument (a) must be subtracted from the zp calculated value for the true zp
