“The Economic Benefits of Commercial GPS Use in the United States and the Costs of Potential Disruption” was presented by Nam D. Pham, Ph.D., of NDP Consulting, during a June 21 webinar sponsored by the Coalition to Save Our GPS. The report states: “The direct economic benefits of GPS technology on commercial GPS users are estimated to be over $67.6 billion per year in the United States.
Interference, detection, and mitigation — these have become topics of paramount importance to the GNSS community recently, surpassing at times even those old familiar standards accuracy, availability, and integrity. In March, a large expert audience attended a GNSS Interference, Detection, and Mitigation (IDM) conference at the United Kingdom’s National Physical Laboratory near London. My conclusions first, followed by reportage of the details.
First Overload Interference/Desensitization to GPS Receivers, Systems, and Networks Report to FCC; Plus Save Our GPS Coalition Forms; WAAS Official Again; EGNOS SOL Operational; Russian SBAS Satellite Passes Transponder Tests
Representatives of the GPS industry presented to members of the Federal Communications Commission (FCC) laboratory evidence of interference […]
A comprehensive methodology combines spectral-separation and code-tracking spectral-sensitivity coefficients to analyze interference among GPS, Galileo, and Compass. The authors propose determining the minimum acceptable degradation of effective carrier-to-noise-density ratio, considering all receiver processing phases, and conclude that each GNSS can provide a sound basis for compatibility with other GNSSs with respect to the special receiver configuration.
