This paper is devoted to the problem of the GPS navigation system’s susceptibility to various types of interferences and indicates in what way they may influence on navigation parameters. Basic principles of working of GPS receivers and possibilities of the influence on navigation parameters are discussed. Main advantages and disadvantages of using the navigation systems are indicated. In particular, moments of reception of satellites’ signals in relation to the distance of a satellite, diagram presenting the generation process of a signal emitted by a satellite, spectrum of the interfering electromagnetic wave with constant frequency and amplitude, failure to identify location in the GPS receiver, results of the studies concerning the influence of interference with the wave having constant frequency and amplitude, results of the studies concerning the influence of interference with the wave having constant frequency and changing amplitude, spectrum of the interfering signal – constant narrow-band sweeping wave, GPS receiver’s application after input of a real signal with correct identification of the location, GPS receiver’s application after input of the simulated signal of the satellite are presented in the paper.
