Translators (with varying limitations*1) are included in the current development for:
Teqc is designed to handle mixed satellite constellations, such as GPS, GLONASS, Galileo, and SBAS; it is 100% non-interactive — to aid in using it with automatically executed scripts — with a command line interface.
There is currently one publication about teqc:
The following links show examples of teqc translation, editing, and quality checking on real data files. Each link brings up a page for that particular format with one or more command lines. On these pages, many links to data files are to binary data files, so be sure to use ftp in binary mode. Most of the sample files were selected at random, except for the ConanBinary file--which is partially corrupted--and the Trimble download fileset--which was selected because of its interesting qc situation (time-variable RFI at the site). The teqc commands used are fairly typical, using only a small number of editing or extra qc options. Download the input files and try the commands yourself. (Note: For the Ashtech and Trimble downloads, remember to get the entire fileset: B-, E-, and S-files for Ashtech and the DAT and MES files for Trimble). ASCII files will look best if viewed with a non-proportional font like Courier.
Qc'ing a RINEX OBS file (say, foobar.obs) is as easy as typing
teqc +qc foobar.obsAdditionally, if a foobar.nav exists, this is automatically included as part of the input and used for position calculations. This automatic RINEX NAV search also applies for names ending in .YYo -> .YYn and .YYO -> .YYN to allow for Berne-convention RINEX names.
A list of all possible qc settings can be obtained by executing
teqc +qc ++configBy examining
teqc +helpthe user can find which qc option to modify to achieve a specific change in the qc option configuration. For example, to suppress plot files, the report file, include a symbol table in the short qc report (stdout), and change the elevation mask to 15 degrees:
teqc +qc -plot -report +sym -set_mask 15 foobar.obsA concise qc symbol table can also be generated anytime with just
teqc ++symMost other qc options have been tuned to settings and values to yield an optimized qc run under most conditions for the most users.
Examine a "teqc +qc +sym" example. Here, only the short report, usually available via stdout, is given.
The executables for the current development version of teqc (15 Mar 2013; see development & release log) for the following OS/platforms can be downloaded (sizes in kilobytes below are for the downloaded .tar.Z for .zip file):
UNIX compressed tar files …
… or Microsoft Windows zip files:
If you don't have a 32-bit zip and unzip utility on your PC for Window 95/98/NT/2000/XP/7/8, be sure you also download 32-bit zip and unzip.
Note to Microsoft Windows users: None of the teqc.exe executables available are MS Windows GUIs; they are all command line programs. Clicking on teqc.exe will only result in a window popping up for a fraction of a second. You must use a DOS emulation window and run teqc.exe on the command line. For example, on MS 2000 or XP, click on Start and then Run, and in the Run window type cmd and click on OK to bring up a DOS emulation window. Do the equivalent in Windows 7 & 8.
