Latest Patents

Keyzer's latest patents include innovative systems for detecting satellite signal spoofing. One of his patents describes a system that utilizes error state estimates to identify spoofing in satellite signals. This system comprises at least one satellite receiver, memory, and a controller that processes the received signals to determine state estimates and error state estimates. If the error state estimates exceed a certain threshold, the system can detect potential spoofing.

Another significant patent involves GNSS spoofing detection using carrier-to-noise (C/No) based monitoring. This system includes a GNSS receiver that provides C/No measurements for signals received from satellites. A processor calculates new C/No comparison values and determines whether any GNSS signals are spoofed based on these comparisons.
