GT is a UNIX X11-Windows based application written in C that can be used to look at and edit GPS residuals or COMPACT plot files from teqc (or the older UNAVCO QC program). The current version of GT can only read GPS residuals output from the Bernese set of GPS programs.
Compact format plot files that are generated by teqc (or QC):
*.ion normalized L2 - L1 ionosphere observable *.iod time rate of change of ionosphere observable *.mp1 MP1 multipath observable *.mp2 MP2 multipath observable *.ele SV elevations *.azi SV azimuths *.sn1 SNR for L1 *.sn2 SNR for L2
There are several different versions of GT along with some support files. The following distributions are UNIX tar files of the GT source tree which includes an executable of GT for the specified computer architecture. This source tree is designed to be added to the source tree of the Bernese software system but can be used in a stand along mode. The directory structure of the tar file is as follows:
EXE -- the executable directory gt -- the executable SRC -- the source directory, contains main source code, make files and additional source directories EPH -- obsolete directory, will soon be removed from distribution app-defaults -- contains the X-Windows app-defaults file for gt compact -- directory with example COMPACT files dt -- source code directory io -- source code directory lib -- libraries for gt (gt.a) lists -- source code directory plt -- source code directory utl -- source code directory bernese -- support files for Bernese software xbm -- bit maps
Non-Bernese users can still use the source distributions. The following is the pertinent information need to use Bernese in a stand alone mode:
An older version of just the executable for Linux (1.93 Mb) is available as well. Soon this will be replaced with a current distribution version. To use this version, get one of the full distributions above and replace the file EXE/gt with this file (uncompressed of course).
