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 interference detection. This protection can detect the use of GPS and GSM cell phone jammer. This function helps to prevent vehicles from being stolen, and can even be used to recover stolen commercial fleet vehicles.

　　In Southern California, the technique is used to study the motion of tectonic plates and to assess the possibility of earthquakes.GPS is used for precision agriculture, mapping fields, improving productivity, and promoting the use of chemical fertilizers.

　　In other words, it is essential to protect the GPS frequency in the modern world. 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 jammer devices will be seen flying around sooner rather than later.

　　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, the driver may spend an hour out for lunch running errands and eating while using the company vehicle. In both cases and in other cases, that driver uses the working vehicle for personal use and may not want to be tracked. Many drivers use GPS signal jammer because they don't want to be followed in these private hours.

　　Many GPS tracking devices offer“Privacy mode” settings. This feature enables drivers (and dispatchers) to hide their driving activities for a period of time.Once enabled, vehicle position, speed and engine data will not be available.However, in special cases, such as accidents, data can be extracted manually to assist in the investigation.Providing a privacy mode may reduce the risk of a driver using a GPS jamming device to protect his personal data from disclosure by an employer.

　　Even without interference detection, you can still capture employees with GPS interceptors.Although drivers may think that using GPS scramblers makes them invisible, doing so actually draws more attention to their behavior.

　　Gps interceptors are dangerous, cheap and easy to obtain.Enabling privacy mode on GPS tracker can prevent employees from using GPS-interfering devices to stop their activities after hours.

　　High-tech models of GPS tracking devices include signal jamming detection, and you can also detect employees using GPS tracker gps blocker by viewing the driver‘s travel history and live map tracking.

　　As we become more and more reliant on GPS, the prospect of a decline in GPS seems more and more alarming.

　　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.

　　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.

　　Interference effectively turns off GPS navigation by sending radio signals on these frequencies, or on frequencies adjacent to those used by the technology.
