Note: In May 2013 this newsletter published a column on “What’s New in GNSS Simulation.” This month, Editor Tony Murfin takes a brief look at a new start-up in GNSS simulation, Skydel, and its software signal simulator. We also provide quick updates on the latest from those simulation companies and others. Skydel Software-defined simulator Skydel provides a software-defined simulator using generic hardware to accommodate system integrators who may have a consumer product or application with GNSS inside, and may not require a full-function simulator. Skydel uses a regular GPU to perform modulate the GNSS signal. The computer can be a laptop or desktop, but must include an Nvidia graphics card. The Universal Software Radio Peripheral (USRP) here is the Ettus N210. Skydel also uses the bladeRF x40 made by nuand, an alternative USB 3.0 Software Defined Radio, and Averna RP-6100 Record & Playback system. “What’s New in GNSS Simulation” Updates Spirent Spirent debuts practical PNT framework for more robust position, navigation and timing systems Threats to GNSS and related PNT applications are more orchestrated and coordinated, with the motivation to disrupt or cause financial loss. The technology to disrupt GPS has also become much more accessible, resulting in GPS vulnerability even gaining attention at hacker conventions. Spirent’s GNSS Interference Detector System helps users solve these problems.
