TrustPoint has shown that its C-band navigation signals can keep working through satellite navigation ...

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 ...

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 ...

June 18, 2025, Mountain View, CA – The SETI Institute and SpaceX have launched a groundbreaking collaboration to help protect sensitive radio astronomy observations at the Allen Telescope Array (ATA) ...

In the search for extraterrestrial intelligence, alien radio signals would be swamped by interference from radio sources on Earth. To confirm, researchers point away from the source and then back. If ...

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 ...

WASHINGTON — Slingshot Aerospace, a company specializing in satellite data analytics, received a $1.9 million contract from the U.S. Space Force to advance technologies for detecting electronic ...

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 ...
