Interference-free GNSS signals are essential for more than just military vehicles and aircraft. Anti-jam systems usually suppress signals from interference sources by means of spatial filtering. These ...

Traficom said late last week it had received "numerous occurrence reports" of GPS signal interference along the border. [Courtesy: Finnair] GPS signal interference has been reported along Finland’s ...

A signal detected by a Chinese telescope and originally reported as possible evidence of extraterrestrial intelligence is almost certainly due to human factors, one of the researchers on the project ...

Satellites depend on radio frequency spectrum to communicate with each other and with ground stations on Earth, but spectrum is a finite resource that’s prone to interference — an issue that’s only ...

Developers and manufacturers of GNSS receivers have always needed to simulate the signals from GNSS satellites to test receivers in their labs and in the field. Now, as the vital role of GNSS for ...

Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

Advances in a plethora of military communication and situational awareness platforms have created unintended repercussions for the U.S. Navy, from the “forest of antennas” that can consume a ship’s ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
