A new plotting program for Windows-based TEQC users

Abstract

In a 1999 issue of GPS Solutions (Vol. 3, No. 1) Estey and Meertens describe a multi-purpose software toolkit for GPS and GLONASS data called TEQC (pronounced "tek"). The program's name reflects its three main functions: translating, editing, and quality checking. TEQC can be used on many different computer platforms, including Windows-based personal computers. This amazingly capable program can be used for converting native binary files from a wide variety of GPS receivers into the standard Receiver Independent Exchange Format (RINEX). It can also be used for editing and quality-controlling existing RINEX files. And it can be used for generating plot files of several different quantities normally associated with satellite observations. This article describes a new C/C++ program which gives Windows-based TEQC users increased flexibility for viewing and printing TEQC plot files. The user can now specify a start and stop time for each plot, a subset of satellites to be plotted, labels for the x- and y-axes, and a title to appear at the top of each plot. The new software converts the original "Compact Format" plot files output by TEQC into PostScript files, which can then be viewed or printed. An additional benefit of PostScript files is that they can be used to provide high-quality, high-resolution graphics for document publishing.
