The GPS jammer is used to block the GPS signal in the car, also called the blocker, which will cause the car loan GPS locator to be unable to transmit the current position data of the vehicle through the network signal, so it cannot be located. If the mobile phone is in this environment, There will be no signal. As for the impact on the device itself.
GPS interference method: GPS interference, like ordinary electronic interference, is also divided into two types: suppression and deception.
Suppressed interference: There are narrow-band interference (aiming type), wide-band interference (blocking type), continuous interference and pulse interference in the interference time. The advantage of suppressed interference is that the technical difficulty is less, but the required interference power is larger.
Deceptive interference It is to transmit interference signals similar to gps jammer, misleading GPS receivers to deviate from accurate navigation and positioning. The advantages of this kind of interference are obvious, the required interference power is small, and the interference effect is much better than the suppression interference. Of course, the technical difficulty of deceptive interference is far greater than that of suppression interference. Because it is necessary to know the GPS satellite code pattern and the message data sent at that time to realize deception, it is quite difficult to understand and master these.
The signal jammer is an electronic device, and it emits frequency when it is working, so it must be radiated. We recommend using it as far away as possible from the shield one meter away. At this time, the radiation is very small, basically similar to the mobile phone, and it will not affect the human body.
- The gps receiver is actually composed of 2 parts
- The first part is to receive satellite signals
- The second part is to calculate the time it takes for satellites at different positions in
- The radio signal screen rate used by the GPS receiver is about 1500mhz
- So it is entirely possible to interfere with the GPS signal.
- We use GPS to receive radio signal transmission with the same signal frequency
- You can interfere with the receiver.
GPS jammer is activated, both the vehicle's GPS locator and mobile phones within its vicinity will lose signal reception, rendering them unable to be located or communicate through network signals.
two types of GPS interference methods: suppression and deception. Suppression interference involves disrupting GPS signals through narrow-band or wide-band interference, continuous interference, or pulse interference. It requires a larger interference power but is technically less challenging. On the other hand, deceptive interference involves transmitting signals similar to GPS signals to mislead GPS receivers, causing them to deviate from accurate navigation and positioning. Although deceptive interference requires less interference power, it is more technically complex because it involves understanding and manipulating GPS satellite code patterns and message data.
It states that GPS jammers emit frequencies while operating, similar to mobile phones, but recommends maintaining a distance of at least one meter from the device to minimize radiation exposure.
GPS receivers, which consist of two main components: receiving satellite signals and calculating the time it takes for satellites to transmit signals to determine the receiver's position. It notes that GPS receivers operate at a radio signal screen rate of approximately 1500MHz, making them susceptible to interference from devices emitting signals at the same frequency, such as GPS jammers.
