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 […]

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. […]

Improving Jamming and Spoofing Robustness with Multi-antenna GNSS Simulation

In this webinar from Spirent, we will explore the challenges of reliably testing adaptive antennas (CRPAs) and provide guidance on establishing test requirements. We will then focus on the use of GNSS constellation simulators for the performance evaluation of advanced anti-jamming and anti-spoofing techniques of GNSS receivers using multiple antennas in an antenna array. Topics […]
