摘要：Disclosed herein is a system for detecting manipulation of a GNSS signal andmitigating against such manipulation. A GNSS receiver receives GNSS signals from a
plurality of GNSS satellites, and calculates event times for each GNSS satellite. The GNSSreceiver then compares a next event time for a particular GNSS satellite with an expectednext event time for the particular GNSS satellite. If the difference between the expectednext event time and the next event times exceeds a predetermined threshold, then theGNSS receiver indicates that signal integrity may be compromised.
