GPS Research Group

The GPS Research Group applies GPS technology to geodetic and atmospheric research. The group pioneered the development of real time GPS network measurements of the atmosphere. As part of its research program, the group assists in the analysis of regional and national GPS network data, providing precise coordinates and 2-D tropospheric water vapor and ionospheric electron density maps in real time. The group is developing water vapor tomography using data from densely spaced GPS single frequency systems developed by UNAVCO.
