CRPA Testing: Achieve High-Performance GNSS Simulation in the Lab with Spirent

Controlled reception pattern antenna (CRPA) systems are the state of the art in maximizing reception of authentic GNSS signals while rejecting interference and false (spoofed) signals. Technologies such as military aircraft, drones, and autonomous vehicles all rely on CRPA systems for reliable and accurate positioning even in interference-rich environments. To ensure the highest levels of […]

GPS Spoofing: New Live Sky Tests Confirm Receivers Are Vulnerable to Attack

It was once considered an esoteric and theoretical type of cyberattack, seen only in James Bond films and academic papers. But radio frequency (RF) location spoofing is now causing real concern for users of GPS and GNSS receivers. The recent emergence of software-defined radios has made spoofing much easier to carry out. By broadcasting a […]

Transportation Requires a Fusion; Now to Test It

Inertial navigation systems (INS), like most navigation systems, have evolved through countless iterations and improvements over many years. An INS, unlike other navigation technologies, does not rely on any external signals or inputs to aid navigation. It is, therefore, extremely difficult to spoof, jam or disrupt the system, and solar flares, ground/sky visibility and climate […]

Challenges of Testing Adaptive GNSS Antennas for Jamming and Spoofing Protection

NOTE: This blog is a summary of a webinar presented with DLR on Wednesday 18th November 2020. You can access the on-demand webinar here. The GNSS threat landscape is evolving, and sophisticated new techniques are needed to protect GNSS-reliant equipment against RF threat sources such as jamming and spoofing. One such technique is adaptive antenna technology. […]
