You’ve probably heard of at least one of those terms in any discussion around GPS anti-jam technology for defense. Because they are all terms that describe essentially the same thing: a specialized ...

GNSS jamming and spoofing pose a significant threat to global security, as satellite-based navigation and timing systems are utilized in various application fields, including critical infrastructure, ...

Exactly a decade has passed since the first major milestone of the GPS-mobile phone success story, the E-911 legislation enacted in 1999. Ensuing developments in that history include: Snaptrack bought ...

Unmanned aerial vehicle (uav) used in the spoofing tests; owned by the University of Texas. A radio signal sent from a half-mile away deceived the GPS receiver of a UAV into thinking that it was ...

GPS services are critical for real-time information on positioning, navigation and time (PNT). Because of the highly accurate and continuous PNT solution provided by GPS in all weather conditions, ...

GPS jamming is a continuing threat. A detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. A team of researchers from Cornell University ...

Limited landing area as well as interference due to wind disturbance and wave motion make shipboard landings of unmanned aerial vehicles (UAVs) extremely difficult. Use of UAVs at sea can enhance the ...

Russian satellites have caused GPS outages of as long as 10 seconds across Europe, according to a new research paper, authored in part by GNSS expert Todd Humphreys. Humphreys is head of the ...

The technique of precise point positioning (PPP) is making inroads in the positioning industry. However, one issue hampering its more widespread adoption is the convergence time required for the ...

No audio available for this content. In the battle for reliable positioning and timing, the U.S. Army is engaged in a multitude of activities, including mounted and dismounted A-PNT (assured position, ...

A report filed with NASA’s Aviation Safety Reporting System and published in June outlines how a passenger aircraft flew off course during a period of GPS jamming and nearly crashed into a mountain.

Upholding the principles of “superior construction, excellent management, and substantial development,” the BeiDou Navigation Satellite System (BDS) implements multifaceted strategies to ensure ...
