At present — thanks to lifting of disturbances in satellite systems for civilian purposes e. Navstar system — the GPS technologies are becoming more and more friendly and competitive in comparison to the classical methods. The concept of a dynamic network is nowadays not only the field of scientific notions. Dynamic networks become to be an everyday life issue. The GPS system — as one of the methods of satellite surveys — allows for execution of a survey in any place on the Earth, in any time of day and night, within a freely defined system of co-ordinates in a real time.

PL EN. Widoczny [Schowaj] Abstrakt. Adres strony. Geodeta : magazyn geoinformacyjny. Figurski, M. Influence of interferences on GPS measurements. Using GPS receivers we come across various problems related to the measurement accuracy. The reasons of measurement failure might be different, but they are usually caused by the external factors. We may assume that the most possible explanation is the electromagnetic disturbance, but we should also remember that electromagnetic influence is not always the reason of GNSS frequencies fading and degrading.
The Centre of Applied Geomatics has done a series of research and the results are described in this article. The influence of external electromagnetic field might be divided into two classes: harmonic frequency which may, in certain environment, influence the GPS signals and so called disturbance on purpose witch is obtained through the use of available disturbance equipment to eliminate GPS signals.
