Abstract
The article deals with the issue of GNNS GPS L1 signal interference. Authors performed experimental measurements at the Žilina airport, where two sources of GPS L1 signal interference were placed. The goal of the experiment was to confirm or to dispel fears of the increasingly undesirable interference of GNSS signals, particularly near highways and expressways, or other transport infrastructure. GNSS signal interference has a major impact on aviation safety and, in particular, in the context of the massive introduction of GNSS approach procedures for airports. Implementing procedures for airports that are also equipped with terrestrial navigation infrastructure (VOR / DME, ILS) is not a problem as there is always the possibility to switch to a terrestrial navigation system. However, for new aerodromes where the GNSS procedure will be approved using only satellite navigation systems without terrestrial expansion, there is a real safety risk in the event of accidental GNSS signal interference.
