The base was set for 1 hour 45 minutes. There were a couple trees nearby, but open sky above about 15 degrees.

Convert the inpurt file to RINEX and run it through teqc to see if it's really a cycle slip problem or something else.

I don't know how to use teqc, I just downloaded it. Looks like it is a DOS base program?

It is a DOS based executable program. There may be a learning curve, but there are all kinds of support for this DOS based program.

DOS Box

Seemed pretty simple considering most everybody from my generation is completely DOS illiterate.

Google up WinTEQC Editor,
www.teqc.silkwerks.com. They have a windows based GUI that simplifies things if your DOS challenged. I use the QC application on the Rinex files to identify cycle slips and other problems. You'll need to dive in to the manual to decipher the codes for data analysis in QC results but you can subsequently turn off the problem SV(s) and resubmit or process resulting edited Rinex file. I'd post more but I'm home fighting off the dreaded crudd. Another tip, install and run everything from one location. Hope that helps some.

Go to WinTEQC Editor and get the WinTeqc editor.

If you want to e-mail me the T01 or T02 file I'll be happy to have a look at it for you.

Just curious,

Did you guys get it figured out?

Yes, Lee provided me some answers. Now I'm trying to figure out how to do it myself.
I downloaded WinTeqc, not sure what that does yet, and RTKLIB, a complicated program, but I think it will work in the long run.

"5 C1 C2 L1 L2 P2 # / TYPES OF OBSERV " is not correct for GPS 02

GPS 02 first line "20959758.328 7 110144272.83017 85826706.32159 20959758.06349" is C1 L1 L2 P2. However in posting here you may have lost the blank spaces that should be there.

I would suggest to edit out all the GLONASS.

Then edit out GPS 02 and then to C1 L1 L2 and P2 if it does not solve.

My problem is I do not know what I am looking at. You see that error, I do not. In time I will but not right now.

Cool...

I just use 'teqc,' it's really easy once you get the hang of it.

Send me that RINEX and I'll look at it and point out oddities to you.

Does WinTEQC work on windows 10? I unpacked the downloaded zip file to C:/WinTEQC/ Then I double-click the highlighted executable.


No matter which RINEX file I input, or which options I choose, I get errors and no answers. I have been through the Power Point Tutorial, read the Unavco Tech Tutorial a couple times, I just can't seem to get any clue what is supposed to happen. I assume if I ever do it right that the OPUS results tab will have some answers. So far it has remained stubbornly blank.

Teqc hates long file extensions. Unzip everything into a single folder and create a subfolder 'Input' and copy your Rinex file into that and open from there and see if that helps.
