GPS Interference

GPS Interference refers to any phenomenon that disrupts the reception of signals from the Global Positioning System, leading to degraded accuracy or a complete loss of positioning, navigation, and timing (PNT) data. This interference can be natural, such as solar flares or atmospheric conditions, but is often man-made, stemming from unintentional sources like poorly shielded electronics or deliberate acts like jamming and spoofing. Jammers broadcast noise to drown out satellite signals, while spoofers transmit counterfeit signals to deceive receivers. As modern infrastructure and military systems heavily depend on GPS, understanding and mitigating interference is critical for operational continuity, safety, and national security.

Key Features:

• Jamming: Overwhelms GPS signals with more powerful radio frequency noise.

• Spoofing: Broadcasts counterfeit signals to provide false location or time data.

• Natural Sources: Includes solar activity and ionospheric scintillation.

• Unintentional Sources: Can originate from other electronic devices or transmitters.

• Poses risks to aviation, maritime, financial networks, and military operations.

• Mitigation involves anti-jam technology, inertial navigation, and signal authentication.
