Performance Analysis of Intentional Interference on Multi-GNSS Receivers

Nowadays Global Navigation Satellite System (GNSS) has been used in a variety of applications, however number of interference actions on the frequency band of GNSS has increased rapidly during the last decades. Research of GNSS resistance methods to interference arose in the late 1990s. This became evident when the first prototypes of jammers targeting GNSS were available in the market. This situation persisted until the suppression of electronic warfare systems was achieved. Currently, available jamming equipment can almost entirely nullify the effectiveness of weaponry and military equipment utilizing GNSS signals. The problem is also arising with multiple privacy protection devices, basic jammers, and GNSS transmitters available at low cost, as the use of such devices leads to unintentional disruption of GNSS signals. Interference and GNSS spoofing are periodically observed in different Flight Information Regions, especially in conflict zones and areas of increased tension. Their impact on aircraft and ground systems is a potential risk to the safety of civil aviation. The paper presents the results of experimental research on impact of intentional interference on multi-GNSS receivers of satellite navigation systems GPS, Glonass, Galileo, Beidou, QZSS.
