A Geodesist's View of the Ionosphere (January 8, 2004)

Precise ionosphere models are very important for accurate positioning by GPS by removing the current distance dependent effects of the ionosphere. Such models would allow single frequency L1 positioning over long distances and provide a useful aid for rapid ambiguity resolution.

GPS & the Solar Storm: (November 21, 2003)

NGS produced AVI Videos that graphically depicts the major solar storm as it swept North America the end of October 2003. The data represented in these movies were derived using GPS technology.
