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.

To learn more about Noffz, visit

Interoperable with GPS and Glonass, the Galileo GNSS constellation is Europe's civilian global positioning system that will reach Full Operational Capability (FOC) in 2019. Simulation of the complete Galileo constellation is possible with Skydel's SDX GNSS simulator.

Upcoming Events in 2017

We’ll be exhibiting at many events in North America and Europe in the coming months. Come visit us at the events listed below: you’ll have a great opportunity to see a demo of SDX and have a chat with a Skydel representative. We always love to hear about your challenges, needs and expectations when looking for a GNSS simulator.

ENC - European Navigation Conference 2017

May 9-12, 2017 | Lausanne, Switzerland | Booth 6

From Wednesday to Friday, come to ENC and attend to technical sessions featuring a number of internationally recognised experts in the field of GNSS.

During session breaks, Skydel will be present at booth 6, featuring SDX. Come by and see multi-constellation simulation (including EU’s Galileo) and the latest features & benefits of our software-defined GNSS simulator.

Oh, and the conference’s location isn’t bad either.

JNC - Joint Navigation Conference

June 5-8, 2017 | Dayton, Ohio | Booth 301

The 2017 Joint Navigation Conference (JNC 2017) is hosted by the Military Division of the Institute of Navigation, for the Department of Defense and Department of Homeland Security.

JNC is the largest U.S. military Positioning, Navigation and Timing (PNT) conference of the year with joint service and government participation. The event focus, among other things, on advances in battlefield applications of GPS; critical strengths and weaknesses of field navigation devices; warfighter PNT requirements and solutions; and navigation warfare.

Skydel SDX will be present at JNC through our partner Talen-X, demonstrating the latest version of BroadSim, featuring advanced jamming capabilities.

Note: Conference attendance is limited to U.S. Government agencies and their contractors.

Rolling out SDX Release 17.1

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

GNSS Signals Simulation with Multipath

Release 17.1 adds a fine level of control on signal multipath. Multipath is a term that refers to the propagation phenomenon that results in radio signals reaching the receiving antenna by two or more paths. In the field of GNSS, this most commonly happens when satellites’ signals are reflected and diffracted before reaching the receiver, for example by hitting objects such as buildings, trees, vehicles or the ground. These signals are often named echoes.

Example of the signal reaching the GNSS receiver through multipath echoes

In urban environments, multipath echoes are a common occurrence. Their effects are non-trivial, as they can compromise the accuracy of the positioning, resulting in errors that can reach tens of meters. To add to the problem, the effects of multipath echoes are notoriously difficult to test “in the real world” with live sky signals: for example, naturally occurring signal echoes cannot be isolated to create a successful test scenario.

GPU-Accelerated Computing: What are the Perks for GNSS Simulation?

We’re often asked why we promote GPU-accelerated computing as our product differentiator. In short, what benefits does using this software-defined architecture for GNSS simulation offer the user?

Today’s GPUs –readily found as COTS (commercial off-the-shelf) hardware– have been typically associated with computer gaming, and have been included as standard equipment into the desktop PC since the late 90s for this purpose. Since then, they have continually improved; and now, they can be used for much more than 3D graphics rendering. GPUs have a highly parallel structure that makes them more efficient than general-purpose CPUs for algorithms that process large amounts of data. At their current price range, they offer an unprecedented price-to-calculation-power ratio.

The multi-core structure of the GPU is perfectly suited to parallel processing, such as the generation of multiple GNSS signals

SDX leverages the computing power of both a PC’s GPU and CPU units. The result is a GNSS simulator that uses affordable COTS hardware instead of proprietary hardware, while achieving top simulation performance.
