SDX Release 17.8 is now out

Adds advanced interference simulation, Gaussian noise, and more

Freshly out from our coding lab, here’s the latest update to Skydel SDX.

While it’s often a quiet time for many, our team of engineers were busy at work during the “lazy days of summer” producing a brand new release of SDX with a host of new features, including a big one that we have been dropping hints about for a while.

Advanced Jammers Simulation

The “piece de resistance” of this new release is the addition of advanced interference capabilities to SDX.

Why is this a breakthrough? The conventional way of testing GNSS interference uses a hodgepodge of hardware and cables in all directions, is complicated to set up, and is still somewhat limited in functionality. We’ve covered this before if you want the details.

On the other hand, SDX already uses GPU-accelerated computing to create GNSS signals. The next logical step was to add interference generation. That’s what Advanced Jamming is about: a unique way to leverage the power of the GPU/SDR combo to create an unheard of way to simulate interferences.

Let’s talk about interferences

For more than a decade now, we’ve been warned about the vulnerabilities of GNSS and the risks of jamming, as well as the general lack of robustness of GNSS-enabled devices to various interferences. The founding architect of GPS, Brad Parkinson, expressed his concerns about the situation a few years ago. As reported by GPS World magazine:

“[Parkinson’s] concerns over GPS availability relate to threats such as the loss of authorized frequency spectrum (implicitly creating licensed jammers), space weather due to hyperactive ionospheric conditions, and deliberate or inadvertent jamming of GPS signals. He warned that GPS is more vulnerable to sabotage or disruption than ever before, and charged that politicians and security chiefs are ignoring the risk.”

Despite recent examples that the situation is both real and serious, not much has been done since to make the various GNSS/GPS devices that we use daily better able to resist adverse conditions. And as we’ll see below, public RF signal usage is both widespread and often embedded in critical public infrastructure—to the obliviousness of many system designers and engineers.

But let’s first rewind a bit and get to the root of the problem.

Automation in Video: The automate panel and the SDX API

Engineers and scientists that use a GNSS simulator know that automating tests and simulation scenarios are an essential part of their work. Alas, it is often complicated to create GNSS automation scripts: it usually requires advanced programming skills, APIs are often badly documented, and the whole process usually lacks any kind of meaningful feedback while setting up scripts.

When we developed SDX, we decided to tackle these problems by building automation right into the core of the software. The result is an easy-to-use, yet very powerful automation toolset. It addresses new users’ needs while providing intermediate and advanced users with all the tools they need to push GNSS simulation to the next level.

In order to better showcase the range of automation features, we’ve created two videos.

Skydel teams up with Noffz

Partnership increases Skydel presence in Europe

We’re really excited to announce our partnership with Noffz, a germany-based company. NOFFZ creates test systems and solutions in the area of the Internet of Things (IoT) - especially in automotive RF-Test applications around eCall, Network Access Devices (NADs), Telematics Control Units (TCUs), Infotainment/Multimedia Units and Automotive Radar.With nearly 30 years of experience NOFFZ delivers worldwide turn-key solutions and PC based Measurement- and Automation systems with an extensive service. With their broad expertise in test solutions, Noffz is well positioned to bring Skydel’s SDX GNSS simulation solutions to clients located in Europe and beyond.

Technology is constantly evolving. With the advent of new satellite constellations, such as Galileo, expanding needs for position and navigation in the transportation industry, and the growing threats of RF interferences, GNSS simulation is more than ever a key component in the arsenal needed to design and validate new products. Skydel SDX delivers a new paradigm in GNSS simulation, featuring an exclusive mix of performance, flexibility and unique capabilities. With the addition of Noffz’s know-how covering multiple industries, we now have an outstanding team that’s ready to tackle today and tomorrow’s technological integration challenges.
