GPS Is Vulnerable to Jamming—here’s How We Might Fix It
GPS is susceptible to jamming, as evidenced by a recent incident involving a Widerøe Airlines flight in Norway during Russian military exercises causing navigation failures. The frequency of GPS disruptions has risen globally, impacting various sectors, including emergency services and agriculture. Agencies like the Department of Defense and the FAA are seeking alternatives and enhancements to GPS, investing in modernization efforts totaling billions. Innovations include higher frequency signals and alternative positioning systems to reduce vulnerability to interference. While improvements are in progress, the reliance on GPS remains a challenge due to its ubiquity and free access.
