Why is GPS stuck?
Courier services and transportation companies install GPS beacons in company vehicles as well as in transport aircraft. With the help of satellites, management monitors the vehicle's route, speed, fuel tank level, parking location and parking duration.
It works around the clock: as long as there are GPS satellites in orbit, this little device calculates and transmits coordinates. You can't turn it off, but you can block the signal.
jammer gps are special devices that block satellite positioning. Not only do they block beacons in transit, but they also block signals in smartphones, phones, clothing.
Blocking can come in handy for a variety of reasons, for example if you suspect you're being followed by a competitor or suitor. Also of interest are those who want to close scheduled routes or travel longer distances in official vehicles.
However, you need to be aware that there are many legal and technical nuances that greatly limit the possibilities of this device.
Here's how it all works:
Our planet receives GPS signals from satellites orbiting at an altitude of 20,000 km. The distance to each satellite is determined based on the time it takes to send the data and the speed of light. The receiver then determines its relative 3-dimensional position in space.
The problem is that the GPS signal gets weaker. And the weaker it is, the more it will be interrupted by interference using special equipment that produces noise. The GPS signal strength received by a receiver on Earth is 4 trillion times weaker than the RF signal of V2V communication in the weakest short-range network.
Governments, communities, and associations are devoting nearly all their resources to addressing a serious vulnerability to GPS, as relatively cheap and extremely effective methods of jamming are available to hostile nations.For example, the current Russian-Ukrainian war.
Of course, terrorist acts accompanied by violence and casualties are much more serious than GPS interference, but if the GPS network is "disabled" on a large scale, it will cause a lot of inconvenience and serious problems for most companies and individuals.
