GPS data processing with GAMIT/GLOBK

GAMIT/GLOBK is a comprehensive GPS analysis package developed at MIT and Scripps for the estimation of three-dimensional relative positions of ground stations and satellite orbits. The software is designed to run under any UNIX operating system supporting XWindows. The primary output of GAMIT is a loosely constrained solution (H-) file of parameter estimates and covariances which can be passed to GLOBK for  combination of data to estimate station positions and velocities and orbital and Earth-rotation parameters.

The workshop is organized in 6 classes/units and can be taken as a self-study course as well.

Course evaluation form
(give us a feedback about the class and/or the web page)

We propose students to process a combination of continuous and episodic GPS data from BARD and the North Bay transect. More information about the data set are available in the GPS DATA SET page. Students are encouraged to work on alternative data sets if they feel this is more convenient for their interests.
