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 ...

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 ...

Using signal-to-noise measurements from a single commercial-grade L1 GPS receiver, it is possible to detect interference or jamming that is above the thermal noise floor and below a power that causes ...

Germany’s Frankfurt International Airport has become the world’s first hub airport to feature ground-based augmentation system (GBAS) landings with an increased glide angle of 3.2 degrees. In March, ...

An ongoing research effort featuring aviation government and industry representatives from Brazil and the United States will look to certify the use of a Ground Based Augmentation System (GBAS) ...
