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 ...

United Airlines, Honeywell and the US Federal Aviation Administration are plotting a slow, but deliberate, return-to-test of a GPS-based precision landing system that was foiled by unexpected ...

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) ...

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, ...

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 ...

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 ...
