Global Navigation Satellite System (GNSS) is seen by terrorists or hostile countries as a high value target. Volpe Center report contains the following statement: “During the course of its development for military use and more recent extension to many civilian uses, vulnerabilities of Global Navigation Satellite Systems (GNSS) – in the United States the Global Positioning System (GPS) – have become apparent. The vulnerabilities arise from natural, intentional, and unintentional sources. Increasing civilian and military reliance on GNSS brings with it a vital need to identify the critical vulnerabilities to civilian users, and to develop a plan to mitigate these vulnerabilities.” GNSS can also be targeted by more common criminals - computer hackers and virus writers. Therefore, there is a need for maintenance and continued development of independent radionavigation and radiolocation systems. This article will compare two Polish hyperbolic systems in terms of radio parameters, functionality and usability.
