Need TGO help, PLEASE!!!!!!!!!!!!!!!!!!!!

Matt
I assume the project has static baselines. If it does, you will need RinexDates to adjust the dates in the file so it will process. You can get RinexDates by clicking on the "services" tab above then selecting it from the drop down menu. Do you have any processing experience?

The files have all been converted already.
I do not have processing experience in TGO, I was familiar with the Old Ashtech Solutions processing, but this is a completely different beast.:-(

I'm not sure what you mean by the files have all been "converted"? Do you mean they have simply been converted from .dat to rinex files or they have already been run through RinexDates or they have already been differentially processed into resolved vectors?

They have been converted to Rinex and thats all. I have imported then into TGO and thats as far as i have gotten. After that its been a trail and error session of reading the manuals and "button pushing".:-S

Ok. The first thing you need to do is run the rinex files through RinexDates before you import them into TGO so you'll need to back up a bit and remove the files you have loaded into TGO.

It's probably worth noting for the benefit of the OP the reason he has to use RinexDates: TGO broke sometime in the fall of 2011, i.e. a date-handling limitation hard-coded into the software prevents it from correctly processing GPS data collected after the break date (the billion-second rollover). Since Trimble had already superseded TGO with TBC, they chose (reasonably, if inconveniently for users) not to invest in a fix for TGO.

Some of the sharper minds in the surveying community realized that if the observations were backdated to a time when the relationship between the GPS second and the GPS week are the same as those of your observation date, you can fool TGO into processing the data correctly. That led to the creation of RinexDates, a way of automating the process. I believe Dario Canosa and Chris Lambert are the primary architects, with John Minor providing testing and support. It's good stuff for those who have no other solution.

Just so's you know.

Thanks Jim

To add to what Jim said, John Hamilton also has a program, FixDatTGO, that does the same thing but uses the .dat file rather than a rinex file. It saves having to go through the rinex conversions but if you need to use CORS data it will be in rinex format so you will need to go the rinex route anyway.

Never mind ...

Try the tutorial??

On the TGO CD there is document titled "Guide to the Trimble Geomatics Office Sample Data.pdf" or something similar.

That document uses the data in a TGO project created using the "Sample Data" template for several exercises including postprocessing and network adjustment.

If you cannot find the CD, send me an e-mail through via the link by my name and I will send you the document via e-mail attachment, it is only about 265 kB.
