What are the types and functions of GPS signal jammers?
GPS signal jammers can be classified based on their type and functionality. Here are some common GPS jammer types and features:
Active jammer: An active jammer is a device that can autonomously emit interference signals. It can analyze received GPS signals and generate corresponding jamming signals to interfere with nearby GPS receivers.
Passive jammer: A passive jammer is a passive device that mainly reduces the sensitivity of the receiver by suppressing and filtering GPS signals, thereby weakening the strength of the GPS signal.
Programmable Jammers: Programmable jammers offer higher level control and configuration capabilities. Users can adjust the parameters of the jammer according to their specific needs, such as the frequency, power and range of the interfering signal.
Vehicle-Mounted Jammer: This type of signal jammer is designed to be installed on a vehicle to block the vehicle’s GPS location under certain circumstances. They are often used for military, security or privacy protection applications.
Portable Jammer: A portable jammer is a small, handheld device suitable for personal use. They can be used in specific situations, such as conference rooms, confidential locations, or where personal privacy protection is required.
High-power jammer: High-power jammer has stronger transmit power and can cover a larger range. They are commonly used in military and security applications, such as protecting military bases or critical installations.
Low-power jammer: Low-power jammer is suitable for situations where smaller range shielding is required, such as conference rooms or offices, to prevent unauthorized GPS positioning.
The main function of the GPS signal jammer is to interfere with or block the positioning signal of the GPS receiver. They can be used in military operations, protection of security-sensitive areas, eavesdropping-proof confidential locations, privacy protection and personal security. However, you must comply with applicable laws and regulations when using a GPS signal jammer and ensure that it does not interfere with the legitimate GPS use of others.
