GPS jamming devices are widely used in many fields
GPS signal jammer are devices that can block the GPS satellite signals, which can disable businesses to track, locate or manage their entire flight in real time if a GPS blocking device is attached to every single vehicle.
These small GPS jammers enable users to defeat efforts to track their vehicles with GPS signals by creating a bubble of RF interference around the vehicle as wide as a quarter-mile. When that vehicle passes by an airport or other facility that relies on GPS positioning and timing, then problems occur.
So will intentional and accidental GPS jamming cause aircraft to fall from the sky or trucks to smash into buildings? That’s unlikely because most mission- and life-critical GPS devices have ample backup to handle intermittent outages, Buensel says.
The recent reports out of Syria highlight the inclusion of these in an evolving battlespace. One of the simplest threats to drones is the blocking or scrambling its reception of a signal from a GPS satellite. This “GPS jamming” can produce serious operational impact on military mission and will likely become more and more prevalent. According to a piece by NBC, Russians are using GPS jamming against the U.S. military’s smaller surveillance aircraft.
The Systems Tool Kit (STK) has a quick tutorial that demonstrates how to determine if a small, hand-held GPS gsm jammer can interfere with your mission. One can also determine how spectrum filters or phased array adaptive nulling can counter this, or design new systems as other phenomenologies to get positioning, such as celestial navigation, that operate in these denied environment.
The situation was similarly serious in September 2017, when airliners from companies SAS and Widerøe in periods had to navigate with the help of radio signals due to loss of GPS when they entered the East Finnmark airspace. The jamming coincided with the major Russian military exercise «Zapad».
GPS jammers broadcast a noise that effectively cancels out the satellites signal despite being such a low powered device. This combination of high efficiency and low power makes them a relatively cheap piece of equipment that can be bought for as little as £15. Each device can simply be plugged into the vehicle’s cigarette lighter, which makes it very easy to operate.
