Introduction

Anthony Pritchard is an accomplished inventor based in Coon Rapids, MN (US). He holds a total of 3 patents that focus on advanced technologies for detecting satellite signal spoofing. His work is significant in enhancing the reliability of Global Navigation Satellite Systems (GNSS).

Latest Patents

One of his latest patents is titled "Detecting satellite signal spoofing using error state estimates." This innovative system includes at least one satellite receiver that receives satellite signals, along with a memory and a controller. The controller determines state estimates from the received signals and identifies potential spoofing when error state estimates exceed a specific threshold.

Another notable patent is "GNSS spoofing detection using carrier-to-noise based monitoring." This system utilizes a GNSS receiver to provide carrier-to-noise ratio (C/No) measurements for GNSS signals. The processor in the system calculates new comparison values based on these measurements and determines if any signals are spoofed by comparing current values with previous ones.
