File Information

Description

TEQC is the Toolkit for GPS/GLONASS/SBAS Data used to solve many pre-processing problems with GPS, GLONASS, and SBAS data.

TEQC stands for Translation, Editing, and Quality Check.

TEQCSPEC(FILENAME) makes a geographically oriented polar plot of multipath in the band 0.04 - 0.07 Hz (default) for a defined time range.

Comments and Ratings (6)
03 Apr 2007	Yunfeng Tian	It takes so much time for waitbar to complete (Fedora Core 6). The import process runs faster when waitbar line (in the loop) is commented.
15 Jun 2007	Easwar Sankar
24 Jul 2008	Victoria Andreatta	The creator of TEQC - Dr. Lou Estey at UNAVCO, Inc. should also be acknowledged. Without him, there would be no TEQC.

10 Feb 2010	Masashi Mochi	When run with 2009b using the included "Ball1830.mp1" : ??? Cell contents reference from a non-cell array object. Error in ==> teqcplot at 44 sats=str2num(A{i});
16 Mar 2010	Tom N	Same problem as above. ??? Cell contents reference from a non-cell array object. Error in ==> teqcplot at 44 sats=str2num(A{i}); Can anybody help?

Updates
16 Nov 2006	Enhanced to plot satellite tracks of multipath in a defined time range
13 Dec 2006	Modified the code to remove system requirement of the Signal Processing Toolbox.
22 Feb 2009	Updated on February 22, 2009 to work with Matlab R2008b. The following functions were added: Checkfile.m, Scanfile.m, and Readfile.m
22 Feb 2009	Updated for MATLAB 7.7 (R2008b). Added new files (checkfile.m, scanfile.m, readfile.m). Fixed a bug on a Wait Bar.
