Statement of the problem. Basic methods of coordinate measurement, implemented in various radio engineering systems, are quite vulnerable. One of the most promising is the one-position coordinate measurement method based on measuring the curvature of the phase front of an electromagnetic wave. However, when implementing it, it is necessary to take into account the change in the electromagnetic parameters of the propagation medium, which affect the accuracy of determining the spatial coordinates of the radio emission source.

Purpose. To assess the accuracy of determining the spatial coordinates of a radio emission source based on measuring the curvature of the phase front of an electromagnetic wave under conditions of a stochastic nature of the parameters of the propagation medium.

Results. In the interests of taking into account the influence of random fluctuations in the dielectric constant of the propagation medium on the accuracy of locating the radio emission source by a single-position method, a simulation model was developed that made it possible to obtain the dependence of the average value of the linear error in determining the coordinates on the dispersion of fluctuations in the refractive index of the medium.

Practical significance. The results obtained can be used in the interests of forming recommendations for the implementation of the method of one-position spatial coordinate measurement.
