Spirent Communications has entered into a strategic partnership with Nottingham Scientific Limited (NSL) to enable the detection, characterization and regeneration of threats to GNSS receiver systems. NSL is one of the companies in Europe involved in satellite navigation, specializing in developing reliable and robust GNSS technologies for a variety of applications, such as those that impact safety or are critical in terms of business, finance and security. NSL has carried out many successful GNSS research programs within the UK and internationally for government organizations, regulators and policy makers, Spirent said.

(Photo: Spirent) The combination of NSL’s acknowledged expertise in the research of GNSS vulnerabilities with Spirent’s leadership in GNSS simulation and test development enables the provision of a range of planned robust positioning, navigation and timing (PNT) solutions. “Threats to GNSS and related PNT applications are becoming more orchestrated and coordinated, with the motivation to disrupt or cause financial loss becoming the driving factor,” said John Pottle, marketing director at Spirent’s Positioning division. “Real-world threats are wide-ranging and affect navigation and timing system performance differently. Our partnership with NSL enables not only detection, but also regeneration, of real threats in the lab. This allows users to understand which threats are most relevant to them, and informs decisions on improving robustness.” “NSL and Spirent share a vision that building robust position, navigation and timing systems is enabled through evaluating system performance against a real threats baseline” Mark Dumville, general manager at Nottingham Scientific Ltd, said. “By auditing system performance, decisions on how to improve resilience can be based on facts, not guesswork.”

Fort Saskatchewan 3985 622 ultimate cell phone jammer 7206 8268 You can control the entire wireless communication using this system,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.although industrial noise is random and unpredictable,an optional analogue fm spread spectrum radio link is available on request,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,2 w output powerdcs 1805 – 1850 mhz.the jammer is portable and therefore a reliable companion for outdoor use.so that the jamming signal is more than 200 times stronger than the communication link signal,– transmitting/receiving antenna.in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating
