After GPS Wing engineers and contractors figure out how to solve the elevation-dependent signal anomalies on the latest GPS satellite — Space Vehicle Number 49 (SVN49), they may want to take a look at another nine Block IIR and IIR-M spacecraft that European scientists say exhibit similar, but less severe, behavior.

In an article that will appear in the July/August issue of Inside GNSS, 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. A version of the article was posted June 25 on the magazine’s website.
