GAMIT-GLOBK


Welcome to the GAMIT and GLOBK home page at the Department of Earth Atmospheric and Planetary Sciences, MIT.

GAMIT, GLOBK, and TRACK form a comprehensive suite of programs for analyzing GPS measurements primarily to study crustal deformation. The software has been developed by MIT, Scripps Institution of Oceanography, and Harvard University with support from the National Science Foundation. The software may be obtained without written agreement or royalty fee by universities and government agencies for any non-commerical purposes. To obtain the download password and be added to the mail list for future updates, please send e-mail to Dr. Robert W King rwk@chandler.mit.edu You must include in the e-mail the full name, address, and telephone and fax numbers of your institution. If you are a student, you must also include the name and email of your advisor or other permanent staff member who will receive the announcements and be responsible for the terms of the license.

GAMIT is collection of programs to process phase data to estimate three-dimensional relative positions of ground stations and satellite orbits, atmospheric zenith delays, and earth orientation parameters. The software is designed to run under any UNIX operating system.

GLOBK is a Kalman filter whose primary purpose is to combine various geodetic solutions such as GPS, VLBI, and SLR experiments. It accepts as data, or "quasi-observations" the estimates and covariance matricies for station coordinates, earth-orientation parameters, orbital parameters, and source positions generated from the analysis of the primary observations. The input solutions are generally performed with loose a priori uncertainties assigned to all global parameters, so that constraints can be uniformly applied in the combined solution.

Current: The current release is 10.40 (November 2010)

The most recent workshops, for which the presentations are available under Documentation, were in Miami in October (Miami10) and Lima in March (Lima11).
