Montreal, Quebec-based Skydel Solutions has released SDX 17.8 software-defined GNSS simulator just in time for ION GNSS+. SDX users now get a host of improvements, according to the company. The 17.8 release menu features, among other things: Gaussian noise, spectrum view and GUI improvements, as well as Advanced Jamming.
Advanced Jamming is an option new to SDX that brings unique interference testing capabilities to SDX users. It leverages the power of the GPU/software-defined radios (SDR) combo to create an unheard-of way to simulate interferences, Skydel states, enabling transmitter trajectories and user-defined waveform creation. It’s designed to be very intuitive and powerful.
SDX release 17.8 brings advanced interference capabilities to SDX, including:
• 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. Create a single or multiple jammer transmitter(s) with user-defined waveforms. Up to 100 interferences can be generated in real time.
• Add dynamics to transmitters. Create realistic jammers for your simulations; SDX’s jammers can change position relative to the receiver as the simulation progresses. During the simulation, SDX automatically calculates the resulting jammer’s signal power at the receiver antenna in real-time and takes into account the transmitter antenna pattern, the propagation loss, and the receiver antenna pattern.
• Use simple transmitters. Create simpler transmitters whose power level is defined from the receiver point of view (as if attached to the receiver).
• There’s no need for additional hardware. Advanced Jamming uses the same hardware combo (GPU/SDR) and is fully integrated into SDX’s GNSS simulation.
SDX’s Advanced Interference allows many new possibilities, such as:
• complex jamming and spoofing scenarios involving land, sea or air vehicles
• complex waveform generation for compliance testing and GNSS receiver testing
• generation of out-of-band interference for non-GNSS interference scenario replication
SDX is multi-frequency (upper and lower L-band) and multi-constellation. SDX uses GPU-accelerated computing and SDR, and is available as complete turnkey systems or software only. Since it is software-defined and uses COTS hardware, it is designed to provide the following benefits: unparalleled upgradability, hardware reuse and economy, advanced features, and high performance/precision. It is suited for design and validation of GNSS receivers, complex integration, academic research, NAVWAR and test engineering.
ION GNSS+ 2017
ION GNSS+, the conference and industry exhibition covering all aspects of satellite navigation technology, will take place in Portland from Sept. 25-29. The company will demonstrate SDX’s latest features at booth #100. Additionally, Skydel’s CTO Iurie Ilie will host a technical session about spoofing on Friday, Sept. 29 — Session B5: Applications in Sectorial Policies.
