As we become ever-more reliant on GPS, the prospect of it going down seems increasingly worrying.
Almost half a century ago, the US Department of Defense started working on an experimental project to launch a series of satellites into space to make it possible to pinpoint any location on Earth.
Fast-forward 47 years, and the Global Positioning System (GPS) is everywhere and in everything from the activity-tracking applications in our smartphones to the navigation systems found in airplanes.
And it became part of the US government's plan, too: in 1983, the Reagan administration declared that it would effectively guarantee and provide GPS for both military and civilian purposes.
Reagan couldn't predict, at the time, that engineers would develop chips cheap and sophisticated enough to power more than five billion smartphones across the world, all fitted with GPS and contributing to a global dependence on the technology.
Jamming happens when too much noise is broadcast by third parties on the same frequencies used by satellites to send data to receivers on the ground, which in turn calculate their location by determining their distance from the satellite.
By sending radio signals on those frequencies, or on frequencies neighboring those used by technology, jamming effectively shuts down GPS navigation.
The US Federal Communications Commission (FCC) is well aware of the issue. It has taken steps to punish the use of jammers gps, which are small devices that send out radio signals on the same frequencies as GPS to override or distort satellite signals.
In Southern California, the technology is used to study the movement of tectonic plates and assess the likelihood of earthquakes. GPS is used for precision agriculture, to map fields and increase productivity while better spreading the use of fertilizers.
In other words, protecting GPS frequencies in the modern world is critical. For that reason, the US Department of Transportation last year published an assessment on "GPS adjacent band compatibility, an analysis of the frequencies neighboring GPS spectrum and of whether they should be used for commercial purposes.
And with Amazon now planning to deploy a fleet of drones to deliver packages straight to our doors, it is likely that more portable jammer devices will be seen flying around sooner rather than later.
Some of the most advanced GPS tracking devices have the ability to detect GPS signal interference. Products such as Azuga's Fleet tracking software include signal jamming detection.This protection can detect the use of GSM and GPS jammers. This feature helps prevent vehicle theft and can even be used to recover stolen commercial fleet vehicles.
Some drivers are authorized to use their work vehicles for personal use under certain circumstances. For example, many drivers take their work vehicles home every night. In other cases, drivers may take an hour off for lunch to run errands and eat while using company vehicles. In both cases and others, drivers use their work vehicles for personal use and may not want to be tracked. Many examples of drivers using GPS signal jammer are because they don't want to be tracked during these private times.
Many GPS tracking devices offer a "Privacy Mode" setting. This feature enables drivers (and dispatchers) to hide their driving activity for a period of time. Once enabled, the vehicle's position, speed and engine data will not be available. However, in special cases, such as accidents, data can be manually extracted to assist investigations. Providing a privacy mode reduces the risk of drivers using GPS jamming devices to protect their personal data from being leaked by employers.
Even without jamming detection, you can still capture employees with a GPS blocker. While drivers may think using a GPS scrambler will make them invisible, doing so will actually draw more attention to their behavior.
When an employee uses a GPS blocker, it shows up as a missed or interrupted trip on a live tracking map or trip history map. Additionally, if a Renegade employee has activated their GPS jamming device during only part of the trip, a line will appear from the scrambler's activation position to the position when it is deactivated. You can even create an exception rule to look for GPS signal errors and trigger email alerts in the event of interference.
GPS interceptors are dangerous, cheap and easy to obtain. Enabling privacy mode on your GPS tracker prevents employees from using GPS-interfering devices to block their movements during off-hours.
High-tech models of GPS tracking devices include signal jamming detection, and you can also detect employees using jammer gps by viewing the driver's travel history and live map tracking.
The GPS satellite positioning system is the most commonly used satellite positioning system in the world. Its predecessor is a "Meridian" navigation satellite system developed by the US military. Space satellite navigation GPS positioning system. After more than 20 years of research and experiments, costing 30 billion US dollars, by March 1994, the constellation of 24 GPS satellites with a global coverage rate of 98% had been completed.
The main functions that the GPS satellite positioning system can achieve in civilian use are:
Vehicle tracking function; the actual position of the vehicle can be displayed in real time using GPS and electronic map, 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; it can also realize multi-window , multi-vehicle, multi-screen tracking at the same time. Use this function to track and transport important vehicles and goods.Of course, the quality of some cheap mobile signal jammer products may not be as good as high priced products.
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.
Emergency assistance function; through the GPS positioning and monitoring management system, emergency assistance can be provided to vehicles in danger or accidents. The electronic map of the monitoring station displays the help information and the alarm target, plans the optimal assistance plan, and reminds the on-duty personnel to carry out emergency treatment with alarm sound and light. , and other human services. With the development of society, GPS positioning system has been applied to more and more industries. It plays the role of early supervision and later management, unified distribution, easy management, improving our work efficiency and reducing costs.
Traffic command function; the command center can monitor the running status of vehicles in the area and make reasonable scheduling of the monitored vehicles. The command center can also communicate with the tracked target at any time to implement management.
GPS satellite positioning system has added a lot of convenience to our life, but at the same time, it has also caused some troubles, and these troubles even threaten the personal safety of individuals.
Personal location information is also very easy to be stolen; current location trackers are getting smaller, lighter, and more accurate, which makes it easier for some criminals to steal and monitor the location information of others. condition.
The location information of the vehicle is extremely easy to be obtained by others; it is only necessary to load a specific GPS positioning device on the body to obtain the vehicle location information in real time. This function is widely used in the vehicle transportation industry and the financial loan industry. In fact, this is also certain. To a certain extent, personal privacy is violated.
Therefore, people with awareness of positioning and tracking will have this demand - how to shield or interfere with the GPS satellite positioning system?

With the emergence and popularization of smart phones, their functions have become more and more perfect and are gradually becoming intelligent.
Your smartphone may know itself better than you do.
Smartphones are an important tool for us today, and they are even more important for us in terms of communication, social networks and storage.
Smartphones have almost become a part of our body and our lives cannot live without them.
It not only records every moment of our life but also stores important information whether it is our personal photos, family photos or accounts.
Information is almost entirely stored in our mobile phones.
This is because smartphones store information about us.
Will you keep track of your private dates? Of course, the quality of some cheap mobile signal jammer products may not be as good as high priced products.
This may be due to the deduction of some labor in the manufacturing process, thereby reducing manufacturing costs.
The low price is understandable.
How to distinguish the products?
This includes comparisons between multiple products, not only based on products and prices between different stores, but also descriptions of prices and quality of products in different stores and many other seemingly identical factors.
Experts say one of the biggest risks of using a self-driving car is that it can be hacked, as any device that uses the internet is vulnerable to such attacks.
With the progress of society and the rapid development of the communication industry, especially the development of 5G technology, mobile communication has brought great convenience to people's lives, and it has also brought adverse effects on confidential places such as prisons, detention centers, and college entrance examination rooms. increasingly obvious.
In the past two years, the incident of candidates cheating through 5G mobile phones has a strong warning effect on the supervision system.
Technically speaking, the essence of the prison full-band gps blocker is electronic countermeasures or co-channel interference, which is to use the frequency band signal emitted by the device through the antenna to make the mobile phone unable to identify and receive the network due to garbled codes when receiving the downlink signal, and the mobile phone displays as No network status, to achieve the effect of shielding the signal.
If mobile phones are brought into prisons and used by criminals, it will cause great harm to the management and security of prisons, detention centers and other places.
Faced with the harm caused by mobile phones, how do prisons block 5G mobile phone signals?
Wireless signal shielding is actually a project with high technical requirements, which cannot be solved by simply purchasing the prison full-band jammer equipment and installing it by yourself. In order to establish a perfect prison cell phone signal shielding system, on-site investigation, power calculation, construction planning, equipment debugging and other processes are essential.
When the prison cell phone jammer needs to be used for wireless signal shielding in large and complex environments, from a professional point of view, high-gain antennas should be used in a wide range and some areas.
The high-angle area is shielded by supplementing the optimized method with a small-range indoor antenna.
Only by establishing a truly effective prison mobile phone signal blocking system can we provide strong security for prisons and detention centers Assure.
The power of the prison full-band jammer needs to be configured and debugged by professionals to achieve the perfect shielding effect of strict shielding in the prison and no interference outside the prison.
