In order to estimate GPS user device parameters in dynamic mode, a special signal simulator must be used. This paper describes testing results when using Satellites Signal Simulator STR4500. For accuracy estimation in the dynamic mode it used different brand devices. The measurements of parameters were implemented in room environments with metallized window glass, as well as in the SAC3 camera, where walls absorb electromagnetic waves. For testing purposes special scenarios for the mobile object movement were generated. The accuracy of the position fix and velocity changes when the parameters of movement change. This paper reveals some of results for the natural experiments as well.
