GPS (Global Positioning System) and GNSS (Global Navigation Satellite System) are positioning technologies that are critical in many industries today. However, the widespread use of these systems has led them to become a target for malicious actors. Jamming attacks to disrupt or block GPS and GNSS signals can cause serious problems in civil and military applications. Here is a review of GPS / GNSS Anti-Jam Systems developed to address such issues:
Jamming Hazard
Jamming is an action that deliberately disrupts or blocks GPS and GNSS signals. This can cause devices to calculate their incorrect positions or not locate at all. Jamming can also have serious consequences in many areas such as civil aviation, maritime, military operations, logistics and even financial transactions. For example, if an airplane is attacked by jamming, safe landing and take-off may be compromised.
GPS / GNSS Anti-Jam Systems
GPS / GNSS Anti-Jam Systems are special devices that protect against such jamming attacks. These systems have the following basic features:
Signal Detection: Anti-jam systems can detect jamming attacks and take measures against these attacks. This allows the system to detect signal distortions or obstructions.
Signal Boost: Anti-jam systems strengthen weak or distorted signals, providing more precise location detection.
Multiple Signal Source: Using multiple GNSS systems, it allows users to access more satellite signals and become more resistant to jamming.
Cryptography and Security Features: Some GPS / GNSS Anti-Jam Systems provide additional protection against jamming and counterfeiting attacks by encrypting signals and adding security measures.
Usage Areas
GPS / GNSS Anti-Jam Systems are used in many areas, from military operations to civilian applications.
Military Applications: Anti-jam systems strengthen the defense of military units against jamming attacks and ensure secure communication.
Civil Aviation: GPS Anti-Jam Systems are critical to ensure safe landing and take-off of aircraft.
Maritime: Anti-jam technologies are used to ensure that ships can cruise safely and enter ports safely.
Logistics and Transport: GPS / GNSS Anti-Jam Systems are used for route planning and inventory management in the transport and logistics industry.
GPS / GNSS Anti-Jam Systems provides defense against jamming attacks by increasing positioning security. Continuous development of these technologies is critical to maintaining the reliability of GPS and GNSS systems.
