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. […]

From RF to I/Q: Why GNSS Receiver Testing is “Shifting Left”

“Shift left” has become a common phrase in the software industry, but not so much – yet – in GNSS receiver development. It refers to the stage of the development cycle at which testing is carried out. In the past, software applications were typically tested only after they’d been written, meaning that whole systems had […]

How to create a realistic, low-latency HIL environment for autonomous vehicle testing

Hardware-in-the-loop delivers accurate autonomous vehicle and ADAS testing – but only with the right test solution. Autonomous vehicle (AV) testing has reached new levels. More companies are fielding more AVs on the road year-on-year, clocking up significantly more testing mileage as time passes. At the same time, the lab testing tools and techniques available to […]

Recent GPS and Galileo issues provide new test cases for receiver developers

Older iPhones and iPads are among the latest devices to experience a GNSS issue. Tech websites including The Verge and The Next Web warned users to upgrade to iOS 10.3.4 or higher before 3rd November, or risk seeing a host of functions fail: from GPS to email, App Store access and 4G/Wi-Fi connectivity. The culprit […]
