It is easy to prove if a jamming device is being used. If you are receiving the vehicle and tachograph data, you will know if the wheels are turning and the vehicle is moving, even though the tracking system will not be reporting any positional data and/or there appears to be a poor GPS signal (a will appear on the map in Mandata Tracking). In addition, you will receive the tachograph data and therefore know who the driver is and when he is driving.
GAJT protects GPS-based navigation and precise timing receivers from intentional signal jammer and accidental interference, ensuring that the satellite signals necessary to compute position and time are always available. It is a Commercial Off-the-Shelf (COTS) product, and comes in versions suitable for land, sea, fixed installations and smaller platforms such as Unmanned Aerial Vehicles (UAVs). Warships, military vehicles and platforms, networks and timing infrastructure can all benefit from the protection that GAJT provides. There is no need to replace GPS receivers already installed, as GAJT works with civil and military receivers including SAASM and M-Code.
A single KAMAZ heavy truck controls three Orlans, one of which acts as a communications relay while the others carry both airborne cell phone jammer and disposable high power jammer they drop to the ground. The whole system, known collectively as Leer-3, can shut down a cellphone network, selectively interfere with only some phones, or broadcast text messages to deceive and demoralize.
But after the Soviet Union fell in 1991, the US Army and Air Force largely disbanded their electronic warfare capabilities. Individual aircraft still have short-range jammers to confuse incoming anti-aircraft missiles, ground vehicles can jam IED detonators at short range, but wide-area, long range jamming was relegated to a relative handful of Navy planes.
