By now you’ve probably heard about the new cave-jamming technology.
While many people are familiar with the technology as a simple form of jamming, a new study suggests that it can also be used to jam GPS signals.
According to researchers, the technique works by creating an electromagnetic field that traps signals sent between two points within a small space, and amplifying that field with a transmitter.
This creates an electromagnetic signal that can be heard and seen.
This can be used for the purpose of jammer jamming or to jam a radio signal, such as a satellite, in order to prevent it from receiving the signal.
“The signal can then be heard from any point on the cave surface,” explained study author, Christopher Ehrhardt.
“This technique has the potential to jam all of the signal sent by GPS and satellites over a large area,” said Ehrhart.
While the effect is somewhat limited, it’s still useful for jamming signals in general, and in the case of satellites it’s useful for satellite communication.
In addition, the jamming technique has a long-term potential to increase the quality of satellite communications.
This new study, however, comes with some caveats.
“While it is possible to jam satellite communications, it is difficult to do so without compromising a satellite’s operational integrity, such that it would become useless for a long time,” wrote Ehrhard.
This means that even with the jammer technique, the effectiveness of jammers will depend on the quality and speed of the jammers.
“This is why we consider the signal to be jamming in the first place,” wrote the researchers.
“A satellite is more than a communications medium; it is a network, which is an important part of the network architecture of the internet,” said Daniel Zolotov, a researcher at the US National Institute of Standards and Technology (NIST).
The authors also pointed out that a satellite signal can be degraded by electromagnetic interference from signals from other satellites and the Earth’s atmosphere.
The researchers used two devices: a device that detects signals that are generated by radio signals, and a device called a radar that can measure the signal strength.
“The device used to detect signals is a radar antenna that is used to measure signals of radio waves, such radio pulses,” explained Ehrart.
“But the device used for measuring the signal, the radar, is actually a transmitter,” he added.
The researchers say that their work is an improvement over previous studies of jam, but it’s not without its flaws.
“Our study uses a very old method to generate the signal that was used in the earlier studies of radio-jammer technology,” explained Zolott.
“But we do not know if the new method can achieve the same result,” said Zolozin.
“It could also be that the signal used in our study is much stronger, and therefore more effective,” said Dr. Ehralds.
“If so, this could give rise to other kinds of radio jamming techniques.”
The researchers also note that the technology could be used by other military or law enforcement agencies, or in military situations where the jam will be used.
