Positioning system technology classification:
In fact, the current position positioning can be roughly divided into two categories: GPS (Global Positioning System) and LBS (LBS--Location Based Service), Beidou GPS positioning system. In terms of technical principles, GPS vehicle positioning is performed by receiving the latitude and longitude coordinate signals provided by GPS satellites, while LBS calculates the location of the mobile phone through the difference of the base station signals of mobile communication, which is often referred to as positioning through mobile phone cards.
The working principle of GPS signal jammer:
The GPS jammer mainly releases radio interference waves, which can disable the GPS locator within the specified electromagnetic wave band, forming the same electromagnetic environment as the equipment to block the signal. At present, it is mainly to shield GPS satellite signals so that data cannot be uploaded to the platform, so that the device cannot be used normally when offline.
In theory, the GPS signal is shielded (the current jammer can be shielded together with the LBS signal), and the car dealer cannot find the vehicle information. Of course, the premise is that the GPS jammer needs to be powered all the time or the GPS locator is removed, otherwise the car dealer It can still be positioned.
Personal privacy and vehicle location protection:
In real life, in order to effectively protect the privacy and safety of the personal vehicle driving route, and some mortgage car behaviors to protect the privacy and safety of the vehicle, the location of the vehicle will not be discovered by others, the use of Sai Yuetong GPS signal jammer, GPS jammer is equipped 6-channel signal transmission, independent switch, car charging, can effectively isolate the mobile phone card positioning and GPS satellite positioning signals, the location information of the vehicle cannot be located in the background, which effectively protects the safety of the property and the user is maliciously installed by the positioning device The privacy and security that it brings.
