　　The main functions that GPS satellite positioning system can achieve in civilian use are:

　　Call traffic command function; the command center can monitor the running status of vehicles in the area and reasonably dispatch the monitored vehicles. The command center can also communicate with the tracked target at any time to implement management.gps jammer can be detected and located by mobile direction finding systems. Spectral analysis to determine the duration and signal type of interference can also be used to indicate whether the interference is accidental or intentional.

　　Route navigation function; providing travel route planning is an important auxiliary function of the car navigation system, which includes automatic route planning and manual route design. The automatic route planning is that the driver determines the starting point and destination, and the computer software automatically designs the optimal driving route according to the requirements, including the calculation of the fastest route, the easiest route, and the route with the least number of highway sections. In manual route design, the driver designs the starting point, ending point and waypoint according to his own destination, and automatically establishes a route library. After the route planning is completed, the display can display the designed route on the electronic map, and at the same time display the vehicle running path and running method.

　　Vehicle tracking function; the actual position of the vehicle can be displayed in real time using GPS and electronic maps, and can be zoomed in, zoomed out, restored, and changed at will; it can move with the target to keep the target on the screen; Vehicle, multi-screen simultaneous tracking. Use this function to track and transport important vehicles and goods.

　　Information query function: Provide users with databases of major objects, such as tourist attractions, hotels, hospitals, etc., users can display their positions on the electronic map. At the same time, the monitoring center can use the monitoring console to query the location of any target in the area, and the vehicle information will be displayed on the electronic map of the control center in digital form.

　　As 5G systems move into frequencies used by GPS, interference is likely to become more widespread. The key point is that civilian signal jammers are completely open, they are not encrypted, they are not authenticated, they are completely open and completely immune to spoofing attacks.

　　GPS satellite positioning system has added a lot of convenience to our life, but it has also brought some troubles, which even threaten the personal safety of individuals.

　　1. The location information of the vehicle can be easily obtained by others; it is only necessary to load a specific GPS positioning device on the vehicle body to obtain the vehicle location information in real time. This function is widely used in the automobile transportation industry and the financial loan industry. In fact, this is also certain. Personal privacy is violated to a certain extent.

　　2. Personal location information is also easy to steal; current location trackers have become smaller, lighter, and more accurate, making it easier for some criminals to steal and spy on the location of others. Health status.

　　The GPS tracker featured in the 2006 movie once raised questions from professionals—at the time, such a small tracker was impossible.

　　As technology advances, the smallest GPS tracker is only a centimeter long, yet its performance is more responsive than ever. Ultra-small GPS trackers will soon go from fiction to reality.

　　The evolution of technology toward smaller and more sophisticated technologies has made GPS tracking more useful for personal privacy theft in addition to commercial espionage.

　　In order to combat the trouble of tracking and positioning, there is gps jamming.

　　GPS jamming is a relatively simple technique that requires only generating an RF signal strong enough to overwhelm GPS satellite transmissions. The subject of a GPS jamming attack will immediately realize that there is a problem because the system will not be able to generate geolocation results.

　　MIT graduate student Limor Fried called her portable jammer a "bubble." GPS cannot enter this bubble for the purpose of reclaiming private space.

　　It's not actually a bubble, it will interfere not only with private spaces or cars, but also with innocent GPS receivers for miles around you. People worried about cracking down on tracking probably won't be uncomfortable with opening the radio bubble.

　　No matter what the goal of the portable jammer is, the device doesn't treat it differently, so there's usually additional collateral damage. Air traffic control (ATC), search and rescue operations, power grids and mobile phone services are all vulnerable to GPS interference.

　　The London Stock Exchange suffered repeated GPS outages, affecting the time stamping of financial transactions. In 2007, an outage in GPS communications at the Port of San Diego prevented residents of the city from withdrawing cash from ATMs, and it took them three days to determine the cause of the ship's drill.

　　While GPS jammers can cause minor disturbances, such as signal loss, they can also pose a large risk to public safety. For instance, jammer gps cannot distinguish between types of communications and may block ingoing or outgoing calls from emergency responders. Additionally, the devices could block more than calls and disrupt all communications within a broad frequency range.

　　The Russian military is buying up jamming devices which it plans to mount on cell phone towers. The idea behind it is simple — the Kremlin could switch on the signal jammer, known as Pole-21 to confuse American GPS guidance.

　　Russia has about 250,000 cellular base stations.

　　As more industries -- like law enforcement and transportation -- rely on GPS-enabled devices, jamming has the potential to interfere with business-critical operations and data. In fleet management tracking, GPS information can be connected to data such as fuel use, driving behavior, engine health, vehicle synchronization and safety metrics.
Therefore, signal jammer can disrupt all of this information and cause major outages.noted that the devices appear to be part of a larger push by Russia to prepare itself for the possibility of major conflict.

　　When we talk of navigation, GPS provides accurate and easy navigation like never before, GPS provides an accuracy that neither of others systems can provide. No matter where on earth you are using a GPS receiver you navigate easily and accurately.

　　GPS jammers were originally developed by the military to mislead enemies about their geographic location and targeting. These devices are then suitable for consumers who want to ensure their privacy or prevent tracking.

　　However, without the proper technical knowledge or in the wrong hands, GPS jammers can potentially disrupt communications by disrupting communications.

　　These days most of our daily routine and critical sectors, like military and aviation industry are highly dependent on GPS navigation.It is shown that jamming can be detected at almost every stage of GPS receiver. The case of intermediate power jamming is emphasized the most, since a GPS receiver is still able to present navigation, which is based upon wrong pseudoranges.

　　GPS jamming is the process of using a drone radio frequency jamming transmitting device to block or interfere with radio communications. Types of communications that can be jammed include phone calls, text messages, GPS systems and Wi-Fi networks. The term is also known as GPS spoofing and the devices used can also be referred to as cell phone or signal blockers.

　　GPS jammers were initially developed by the military to misguide the enemy about geographic locations and targets. The devices were then adapted for consumers that wanted to ensure their privacy or prevent tracking. However, without proper technical knowledge or when placed into the wrong hands, GPS jammers can cause potentially damaging disruptions in communications.

　　GPS jamming devices can be used for a variety of applications, such as:

　　Concealing the location of a device or vehicle.

　　Inhibiting mobile devices from being able to make or receive calls, text messages or emails.

　　Hiding, changing or obscuring positioning signals from GPS units.

　　Blocking Wi-Fi enabled devices from successfully connecting to the internet.

　　While GPS jammers can cause minor disturbances, such as signal loss, they can also pose a large risk to public safety. For instance, GPS jammers cannot distinguish between types of communications and may block ingoing or outgoing calls from emergency responders. Additionally, the devices could block more than calls and disrupt all communications within a broad frequency range.

　　As more industries -- like law enforcement and transportation -- rely on GPS-enabled devices, jamming has the potential to interfere with business-critical operations and data. In fleet management tracking, GPS information can be connected to data such as fuel use, driving behavior, engine health, vehicle synchronization and safety metrics. Therefore, jammers can disrupt all of this information and cause major outages.

　　Once the signal jammer is operational, you can practice testing it by monitoring the signal on a common consumer GPS receiver or high quality communications receiver. A GPS receiver close to the jammer will not be able to acquire C/A-code lock and any operating GPS in the jammer's radiation pattern will lose C/A-code lock. Higher quality GPS receivers tend to be less susceptible to low power jamming, so you'll need to be in the antenna's near-field radiation pattern (i.e. close) for it to work.

　　Any obstructions near the jammer's own antenna (trees, houses, hills,walls, etc.) will decrease the jamming range. The best placement is where the jammer's antenna is line-of-sight to the antenna of the GPS receiver you're trying to jam. Real world results will vary drastically, but you should be able to obtain a jam radius of a few hundred feet even in heavily obstructed areas with the higher power (AH102) option and a simple antenna.

　　You can even practice counter-jamming methods to protect yourself against hostile or accidental GPS jammers. Try to shield your GPS receiver from the interference source by placing your body, trees, hills, rocks or other obstructions in-between your position and the interference. More advanced methods involve using directional or steerable phased-array antennas on your GPS receiver (pointed skyward) to nullify any ground based interference.
