The article of the methods for coordinates determination of the object coordinates are reviewed. The advantages of a passive method with the using of the direction finder are noted. The problems arising from the transmission of signals in the direction finder method are determined. The construction for the signal transmission of the fiber optic communication line is presented. It is established that the greatest influence on the error in determining the coordinates of the object by direction finder has a phase shift in the optical fiber during a change the temperature. The chart of the phase shift at the temperature for various cases of optical fiber placement are investigated. The obtained data of the experimental investigations are presented.
