Patent number: 11668835Abstract: Systems and methods for GNSS spoofing detection using C/No based monitoring are provided. In certain embodiments, a system including at least one GNSS receiver that provides C/No for GNSS signals received from GNSS satellites. The system also includes a processor coupled to the at least one GNSS receiver.

Patent number: 11585941Abstract: Techniques for detecting GNSS spoofing using inertial mixing data are disclosed. One or more navigation parameters are determined by at least one GNSS receiver and a plurality of IRS from at least two periods of time. The navigation parameters from the GNSS receiver(s) and the IRS are compared at each time period, and the difference(s) between the compared navigation parameters are further compared to generate at least one differential value. A system can detect GNSS spoofing by comparing the at least one differential value to a suitable threshold. In one aspect each IRS navigation parameter is compared with a corresponding GNSS navigation parameter, wherein the plurality of differential values is mixed before threshold comparison. In another aspect, each IRS navigation parameter is mixed before comparison with a GNSS navigation parameter, and the resulting differential value is then compared against a threshold.Type: GrantFiled: September 16, 2020Date of Patent: February 21, 2023Assignee: Honeywell International Inc.Inventors: Gary Duane Lemke, Karl Abraham Keyzer, Mark A.
