Update
Dario,
many thanks for the insight ...
In the header of the nav file is another GPSweek nr. that I changed the same way,
some screenshots of the edited fields.

Update
Things look promising. Dario, Christof, Loyal and I have been working on rinex files from day 258 sta DDSN and CABL.
I have processed the edited data in both TGO and TBC then the unedited data in TBC (of course the unedited data will not process in TGO) Now we need to compare the results but the good thing is that the edited data now processes in TGO.
Update
Hello everybody,
Thanks Dario for your trick !
So, I've got some strange things when modifying rinex files. TGO now accept to open and process base lines, but return an incredible Varref (reference variance) for some post processed points. I've got 2 187 369 meters !!!
Some points are not affected by any error during the base line proccess, but I've found that the coordinates are exactly the same before and after base line processing.
Is somebody got the same problem ?
I didn't found the solution a this time, but I'll keep you in touch in the furtur.
PS : I apologie for my bad english.

The apparent problem is that GPS time reached 1 billion seconds since 1980...
WHY since 1980??? GPS system is used by surveyors from cca 1993, TGO is software for Win XP and Windows XP exists since 2001...
What's this bug from TRIMBLE??? 🙁
According to computers, the world began Jan 1, 1980. Computers count time in seconds beginning on that date. If you remember, all DOS programs using time use seconds beginning at 12:00 am Jan 1, 1980.
Thanks for your reply. But TGO is not DOS program. And ... why other softwares (in this issue: TBC, GNSS Solutions) are OK?
I try another DOS programs and - no problem, they are functional.
We work with satelites and we must "manually" editing rinex files (6y, 313m) and give thanks not to Trimble's techniks but to Dario Canosa for emergency solution...
I don't know if it is good Trimble's business strategy :-S
GPS time is measured in weeks and seconds of week. week zero was 1/5/1980. I think it is pure coincidence that computers default to 1/1/1980.
I started using GPS in 1986, not 1993. And there were static jobs done as early as 1984.
> WHY since 1980??? GPS system is used by surveyors from cca 1993, TGO is software for Win XP and Windows XP exists since 2001...
TGO uses the WAVE baseline processor that was also used in GPSurvey, and possibly even earlier applications. The code base was probably transplanted into TGO with as few modifications as possible, with no consideration given to the possibility that some of the variables didn't have a large enough memory allocation to handle time values in excess of 10^E9. That's my surmise, anyway.
The WAVE processor is based in the original TRIMVEC code that we used in the late 1980s first as DOS command line launched and later in the Windows 3.1 shell.
Sheen....
Pwde po ba kayo mag salita n wikang english kasi hindi ako nakaka-intindi ng tagalog..If u dont Mind..salamat. 🙂
> dili ko kasabot sa imo giingon angel
To: Mr Sheen Suba.. What I mean to my messages is, Pwde ba kang mag-eninglish kay dli ko kasabot sa imohang dialect..Thank u again. Salamat. 🙂
PS: If you can type in English, that would be much appreciated as our other users cannot understand you.
I have no idea if that was all in reply to my post, I have no jibberish translator. Angel seems to speak the lingo.
Northern...
Part of it was....
NAMRIA ano masabi nyo? Translates to: NAMRIA, need I say more?
SO I explained to him that almost no one will know what he meant and asked him to talk in English, and said thanks. He said Angel I wont do that. (Smart alec!!) So I explained to him that no one here understands tagalog dialect...and he thinks that you guys should and it should be multi cultural, and again is being a smart alec. I'm beginning to wonder if he's a spammer??? 😐
Northern...
what language?, I thought it was a spoof...

> what language?, I thought it was a spoof...
No, he's speaking in Filipino. And starting to be a smart ass. He wants you guys to also speak in Filipino, but doesn't want to speak in English. 😐
Hey Ricky,
I just uploaded something I have been fooling with and you guys are most welcome to give it a try. It will subtract the 5 or 6 years from the RINEX files. You can get it from http://teqc.silkwerks.com It also runs TEQC from a menu interface. I make no guarantees or warranties.
I wouldn't mind spending some more time enhancing this if folks sent me in suggestions.
Just unzip it in a folder and she should start working without installation. I am running it on Windows 7 and have tested it on Windows XP.
I don't even have TGO anymore so I can't test the output RINEX with the WAVE Processor.
