Interference background and impact
Since the outbreak of the war in Gaza, Israel's GPS jamming activities in the region have increased significantly. Israel's move is aimed at deterring attacks on its territory by Hamas and the Lebanese armed group Hezbollah. However, these disruptive behaviors have had a significant impact on civil aviation flights, especially when arriving at Beirut Airport, and airlines have had to use GPS alternative systems to ensure landing safety.
Flight cases and countermeasures
In a recent incident, a Turkish Airlines flight hovered over Beirut Airport for about 40 minutes and had to return to Turkey because it could not use the GPS navigation system normally. The incident highlights the potential threat GPS signal jammer interference poses to flight safety. Although using a GPS replacement system can ensure a safe landing, interference and "spoofing" behavior increase the complexity of flight navigation.
Effectiveness of alternative systems
Industry insiders point out that although the GPS alternative method is completely safe, the practice of "spoofing" - that is, sending false signals to cause aircraft receivers to calculate the wrong position - is still a serious problem. In this case, the aircraft relies on ground-based equipment for navigation because these devices are immune to jamming and spoofing. "If they're not using GPS signals, they're using terrestrial devices, which are not susceptible to any spoofing," one expert said.
Electronic warfare and civil aviation security
Israel's interference not only affects military targets, but also poses a threat to civil aviation security. Airlines and pilots must adapt quickly to these changes to ensure the safety of passengers and crew. Experts believe that although GPS replacement systems can temporarily solve the problem, in the long term, more effective countermeasures must be found to ensure the safety and punctuality of flights.
