  4. Real Time GNSS & eLoran Integrity Monitoring at Point of Use GAARDIAN - Challenges  Manage vast amounts of data  In real time  Report unambiguous integrity  On different parameters  In all environments  Verify the new Anthorn Loran signal GAARDIAN - What, How, Who ???  What are the causes?  How will PNT systems be affected?  Who is concerned? GAARDIAN - Deliverables  24x7 Web enabled sensor network  Locally deployed in the vicinity of the user  Deploy trial sensors to both analyse data  & Test integrity monitoring thresholds Chronos Technology Ltd , Stowfield House, Upper Stowfield, Lydbrook, Gloucestershire, GL17 9PD 11/24/08 4 www.chronos.co.uk T: +44 (0) 1594 862200, F: +44 (0) 1594 862211

  5. GAARDIAN – What are the Causes? All known failure modes including  Interference  Scintillation  Multipath  Jamming  Meaconing  Space Weather  Additional Secondary Factors (eLoran) Chronos Technology Ltd , Stowfield House, Upper Stowfield, Lydbrook, Gloucestershire, GL17 9PD 11/24/08 5 www.chronos.co.uk T: +44 (0) 1594 862200, F: +44 (0) 1594 862211

  6. GAARDIAN – How will PNT Systems be affected? Different systems will exhibit different vulnerabilities Different user groups will be susceptible to different vulnerabilities Vulnerabilities will be evident at different times  Environmental impact – weather & space weather  Sensor Location Will problems be systematic or non-deterministic? What new applications will real time 24x7 monitoring enable?
