Skydel Solutions has released SDX Release 17.8, which offers a host of improvements, according to the company. The 17.8 release offers an advanced jamming feature, as well as improvements for Gaussian noise, spectrum view and the graphical user interface (GUI). The new advanced jamming option provides unique interference testing capabilities for SDX users. It leverages the power of the GPU/SDR combo to create a new way to simulate interferences, enabling transmitter trajectories and user-defined waveform creation. Skydel Solutions will be exhibiting at ION GNSS+ in Portland, Oregon, in booth #100. Attendees can learn about the new system and watch a demonstration of SDX’s latest features. Also, Skydel’s Iurie Ilie will host a technical session about spoofing on Friday, Sept. 29, at the conference. With SDX’s Advanced Jamming package, users can: Create user-defined waveforms. Chirp, CW, BOC, AWGN, BPSK and pulse interference modulation are supported and can be combined at will to create custom, complex interference waveforms. Create multiple real-time jammers. Users can create a single or multiple jammer transmitters with user-defined waveforms. Up to 100 interferences can be generated in real time. Add dynamics to transmitters. Users can create more realistic jammers for simulations; SDX’s dynamic jammers can change position relative to the receiver as the simulation progresses. Their power levels are defined from the transmitter’s point of view. During the simulation, SDX automatically calculates the resulting signal at the receiver antenna in real-time and takes into account the transmitter antenna pattern, the propagation loss and the receiver antenna pattern. The transmitter, like the simulated receiver, has six degrees of freedom. Furthermore, the trajectory may even be defined in real-time using the hardware-in-the-loop API. Read more on Skydel’s blog.
