GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) ANTI-SPOOFING TECHNIQUES

摘要: A system for identifying spoofed navigation signals includes a multi-element antenna configured to receive plurality of signals. The also at least one processor determine an angle arrival each the and analyze angles whether or more are spoofed. To signals, may be (i) two were received substantially same (which based on difference less than 5° between arrival) and/or (ii) compare expected information about actual positions multiple satellites).
