What is GPS and GNSS?
GPS (Global Positioning System ) is a positioning system that allows users to determine their locations using signals from satellites around the world. If GNSS (Global Navigation Satellite System) is a general term covering different positioning systems worldwide and includes other systems as well as GPS, for example GLONASS (Russia), Galileo (Europe), Includes systems such as BeiDou (China).
What is Jamming?
Jamming means deliberate disruption or blocking of GPS or GNSS signals. This can be done by malicious users or enemies. Jamming prevents GPS and GNSS systems from working properly, which can lead to serious consequences. For example, many sectors such as civil aviation, military operations, maritime and logistics are dependent on GPS and GNSS.
GPS / GNSS Anti-Jam Systems
GPS / GNSS Anti-Jam Systems are designed to protect against such jamming attacks. These systems can include the following main components:
Antennas: Specially designed antennas are used to enable anti-jam systems to operate effectively. These antennas minimize signal distortions and increase signal strength.
Anti-Jamming Algorithms: Anti-jamming algorithms used in GPS / GNSS receivers detect and correct signal distortions. These algorithms take measures against jamming for reliable location detection.
Signal Boost: Anti-jam systems can strengthen weak signals, resulting in a more reliable location detection. This feature makes it more resistant to jamming attacks.
Multiple Signal Source: Anti-jam systems can use multiple GNSS systems to avoid being dependent on only one signal source. This helps systems become stronger and more reliable.
GPS / GNSS Anti-Jam Systems are used in a variety of fields, from military applications to commercial and civil use. Some examples are given below:
Military Applications: Military units use GPS / GNSS Anti-Jam Systems to protect against enemies’ jamming attacks.
Civil Aviation: Airplanes need anti-jam systems for reliable location detection as they operate based on GPS / GNSS systems.
Maritime: The maritime industry uses GPS / GNSS Anti-Jam Systems to ensure that ships can cruise safely.
Logistics and Transport: Logistics companies and the transport industry rely on GNSS systems for route planning and inventory management. Therefore, protection against jamming is important.
GPS / GNSS Anti-Jam Systems play an important role in many industries that depend on such systems and increase their reliability and protect against jamming attacks. Continuous development and updating of these systems is important to provide more effective protection against signal distortions.
