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 ...

The vulnerability of the global positioning system, or GPS, is widely acknowledged. Radio frequency interference caused by jamming and spoofing is used to degrade a vital synchronization system ...

For the first time, NASA has detected a signal from the Global Navigation Satellite System (GNSS) nearly 250,000 miles from Earth. The signal was part of the Lunar GNSS Receiver Experiment (LuGRE) ...

UAV Navigation ensures that Alpha platforms A-900 & A-800 can carry out missions even with GNSS signal denies or under jamming attack. The majority of Uncrewed Aerial Systems (UAS) rely on Global ...

In today’s interconnected world, the reliability of Global Navigation Satellite System (GNSS) signals is paramount. These signals underpin almost every aspect of modern life, from navigation and ...

Accurate smartphone positioning in dense urban environments remains challenging due to signal blockage, multipath effects, and unreliable satellite visibility. This study presents a new positioning ...

In a pioneering move to bolster the precision of Global Navigation Satellite Systems (GNSS), researchers have crafted advanced processing techniques for subcarrier modulated signals. These innovations ...

It's the first time in history when that NASA has implemented GPS signals on the Moon and it is an important milestone of ...

Fraunhofer ISE researchers have investigated whether PV panels installed above orchards can affect the reception of global navigation satellite system (GNSS) signals and, in turn, affect the precision ...
