GPS signals are of time-spatial nature. And they should be modeled as such in the algorithms for establishing navigational measurements. Therefore, they should be treated as stochastic processes. This article prcsents the results of testing the correlation properties of GPS/DGPS signals. Several measurement series were carried out to obtain position co-ordinates at various times and in various points as well as synchronous measurements of two GPS/DGPS receivers. The tests aimed at identifying the function of auto-correlation between and co-ordinates and the function of intercorrelation between and coordinates. As it turns out, these measurements are significantly correlated, and the mean time of correlation is within the range of a couple or more minutes.
