In-vehicle GPS jammers are mainly used to protect personal privacy and property safety but also to help protect the security and privacy of special industries. The devices are usually small and portable, can be plugged directly into a vehicle's cigarette lighter or USB port.
The functions and uses of vehicle GPS jamming device are mainly reflected in the following aspects:
Protection of personal privacy: In some special cases, individuals may not want their whereabouts tracked by GPS, to avoid being tracked by criminals through GPS location. vehicle GPS jammer can effectively interfere with GPS satellite signals, to protect the user's whereabouts privacy and information confidentiality, to hide the location, to protect personal privacy.
Property security: For some users, vehicle GPS signal blockers are very important. , for example, mortgage car company in order to prevent the car from being secretly taken by the original owner, will install GPS shielding in the parking lot and the car, so that the original owner can not locate the car, to protect the safety of property. In order to protect property, car buyers will also buy GPS signal blockers, to prevent vehicles parked in the middle of the night by someone else.
Company vehicle management: some companies may use GPS blockers to prevent employees from using company vehicles without permission or using GPS tracking vehicles during off-hours, to maintain the safety of company assets and employee discipline.
Special industry applications: In special industries such as the military or government agencies, in-vehicle GPS jammers may be used during certain sensitive periods to protect the security and privacy of operations.
In addition, vehicle GPS jamming device has the features of interfering only with GPS satellite signals but not affecting the normal answering of mobile phone, small size, power, light weight, wide coverage, convenient to carry, etc. can effectively prevent the positioning and tracking of car/mobile phone GPS satellite positioning system. These devices usually block the signal by emitting radio interference waves to disable the GPS locator within a specified range of electromagnetic waves forming the same electromagnetic environment as the device.
