Does anyone know of a program that will convert Trimble ".dat" files to RINEX so I can bring Ashtech Solutions?

Trimble used to have a program called dat2rin.exe that would convert.

It used to require a key, but I think it's shareware now. Suggest you contact Trimble or a dealer to get a copy.

The University NAVstar Consortium UNAVCO has an excellent converter available for download at:

The downside of teqc is that it expects you to know the correct command syntax. A manual is available at the same site.

The program "teqc" is short for translate, edit and quality check. You can merely translate a .DAT file into an observation file. It can also create both the observation and navigation files, create multipath plots, ionosphere plots and an excellent summary of the observations.

If I remember correctly, the syntax to convert a Trimble *.dat file to RINEX is:

teqc -tr do -week 1148 alfa0080.dat > alfa0080.02o

"1148" in the example above is the current GPS week and needs to be correct. The value before the ">" is the Trimble format file the name after the ">" is the name of the file to be created.

You need to input the GPS week due to some problems correctly identifying this value from the file. If it is not entered, I believe it defaults to the current GPS week taken from your system clock.

HTH,

Thanks guys, I didn't post it, but I put David onto the AIUB (University of Berne) converters. These were developed by Dr. RINEX (Werner Gurtner), and are bulletproof.

Thanks for the responses.
