[QUOTE="Pheasant Surprise, post: 1633472, member: 1103"] "The future GNSS signal designs (GPS, Galileo, GLO-NASS) are combating against unintentional and inten-tional interference with, for example, longer codes, dataless pilot signals, and higher transmission powers, and overall, it is much more complicated and expen-sive to jam multiple frequencies at the same time. Systems all over the world have been created to detect jamming/interference. For example, in Britain, the Senti-nel research project used 20 roadside monitors to detect the use of jammer (Vallance, 2012) and the GAARDIAN project monitors the integrity, reliability, continuity and accuracy of the locally received GPS and eLoran Radio Navigation signals creating an alarm network (GAARD-IAN, 2012)." [I]The GAARDIAN project is a UK Government funded collaborative R&D project to develop solutions for analysing interference phenomena assiciated with Positioning, Navigation and Timing (PNT) signals, including GPS and eLoran in safety and mission critical applications. The industrial and academic collaboration is led by Chronos Technology Ltd, includes University of Bath, General Lighthouse Authorities, BT, Ordnance Survey, National Physical Laboratory and Imperial College London.[/I] [URL]http://www.chronos.co.uk/index.php/en/gaardian[/URL] Have you heard of this stuff [USER=1005]@Robt[/USER] ?
