Sometimes the jamming signal arriving at the receiver input, can be lower than the communication (“partner’s”) signal and still prevail. This is happening because usually the receiver needs a certain “margin” between the two signals at its input, in order to be able to interpret one of them (usually the stronger one). However, in advanced communication systems, this “margin” can sometimes be even negative (meaning that the communication signal can be much lower than the jamming signal), and the receiver will still be able to interpret the “partner’s” signal, making jamming a much harder task.
The South Korean capital lies about 50 kilometers from the border region so a signal jammer with such range could disrupt or wipe out GPS signals in Seoul and the surrounding area. The city and region up to the border is littered with military installations and equipment, a lot of which makes use of GPS satellite positioning signals.
The U.S. Navy has entered the final phase of development of the Next Generation Jammer (NGJ) pod that will replace the ALQ-99 that has been in use since the Vietnam War. The new electronic attack pod matches advanced electronic-attack technology developed by raytheon, that combines high-powered, agile, beam-jamming techniques with cutting-edge, solid-state electronics.
Prepares to launch a drone in a joint base with Iraqi army on the outskirts of Mosul, Iraq. A vehicle-mounted signals “cell phone jammer” provided to the Iraqi security forces by the U.S. have greatly reduced the ISIS drone threat in the battle for West Mosul, according to Iraqi generals.

The Next Gen Jammer will respond to these factors with higher equivalent isotropically radiated power, increased number of assignments, digital-based waveform modulations, coherent countermeasures, wideband spectrum, clear spectral output and open architecture, among others.
