There is also no way the jamming device would be allowed to jam essential safety frequencies so there are some frequencies you could fly your drone with criminal intent and be fairly sure they would not get cell phone jammer. Then you have the self flying – no reason a drone can’t fly a programed course and that would be pretty much impossible to affect with jamming – shut down the navigation satilite bands and maybe eventually its dead reckoning would become imprecise enough to have issues, but if you are really in the mood to do something so stupid its not hard to use direction finding based on the local FM radio station towers, map markers, sun position etc and keep accuracy in the dead reckoning.

If the signal-cell phone jammer fails, then the buggy's radar technology can direct conventional missiles towards the same target to finish it off. The radar can detect targets ranging from small commercially available drones up to bombers and passenger jets, at heights ranging from 30 to 30,000 feet.LMADIS engagement procedure goes something like this: the RPS-42 detects the drone on radar, or alternately Skyview detects the back-and-forth radio signals between the drone operators and the drone itself. Next, the electro-optical/infrared camera is trained on the incoming drone to make a positive identification as friendly or hostile. If hostile, the Marines aim the MODi jammer at the drone and prevent the drone operators’ radio commands from reaching it. Gravity takes care of the rest.

Electronic warfare (EW), the use of the electromagnetic spectrum to foil enemy forces and protect friendly ones, is perhaps the most time-sensitive of all the weapons in the military arsenal: a matter of nanoseconds could make the difference between life and death. That’s why latency is so critical to EW processing systems. If a radar-guided missile is heading for your aircraft at Mach 5, the aircraft’s radar jammer had better be quick – quick to take in the signal, manipulate it, and retransmit it to fool the adversary with false targets or misleading data on size, distance, heading, speed. Digital RF memories (DRFMs), the specialized RF jammers that do just that, require receive-response latencies of 20 to 100 nanoseconds. Compared to radars – which transmit pulses and receive echoes – DRFMs – which receive pulses and retransmit the signals modulated with jamming techniques – have much more stringent latency requirements.

DroneGun MKIII, which was announced in mid-July, is centred on a pistol-shaped, portable UAS jammer that weighs less than 2 kg, according to the company. It is designed to operate as a standalone unit or in combination with the company's other products, notably its RfPatrol body-worn UAS detection device and the DroneGun Tactical C-UAS system.

The NERO F5 is developed and manufactured by the French Company MC2 Technologies. It is a microwave jammer capable of disrupting and neutralizing all communication protocols used by drones. The product is based on a portable rifle offering great flexibility for operators in terms of detection, tracking and neutralization.

And a lot of devices jamming signals now on the market and the normal use of the tracking device is a mobile phone signal tracking devices and GPS tracking device, so if people need to cut off the signal tracking GPS and a mobile phone tracking device, if you wish, you can come directly, to see concrete examples of the design of this feature, you can come here to know more details about this' Bluetooth portable signal option 3G mobile phone GPSL1 GPSL2 GPSL5 jammers' and you can see this hand mobile phone GPS 3G jammer details.
