GPS signal anomalies

InsideGNSS reports an interesting news on the SVN49 anomaly. In the article Tim Springer and Florian Dilssner, GNSS engineers in the Navigation Support Office of the European Space Operations Center (ESOC), described the effects of the anomaly as well as the U.S. Air Force’s initial attempts to solve the problem by altering the broadcast satellite orbital positions and time.
