Even if you use GPS-only data, you can run into trouble with the difference between L2C and L2P P2 and C2 pseudoranges if you are not using the .g option and .tgd files.  Enabling certain tracking options requires you to use the -g option and .tgd files; otherwise, you can end up with a RINEX file where some satellites have missing L2 psedoranges.

Thanks Lou for the info.  I am only using GPS satellites.  Trimble requires the payment of
additional fees for other constellation signals…

dear Javier,

Be advised:

Alberto's script does not have the '-g' flag on the `runpkr00` command, meaning
that it will only produce a .dat file, and never a .tgd file, (according to the
information that we have from Trimble) and therefore be restricted to having only
GPS (and maybe SBAS) legacy observables, even if the receiver creating the .t02 file
is configured for tracking other GNSS systems or newer GPS signals.

See more details in the link that I sent.

Hello Javier,
As Lou and Jeff stated, you will need Trimble proprietary software to make the conversion.  I am assuming you are not downloading
the data straight from the receiver since it does have a way to convert to different RINEX versions and even in the Hatanaka
compression versions, as well as in BINEX.
Below is a modified version of a script I use in Linux to convert the T02 files after downloading them from campaign receivers.  The script assumes you have
already runpkr00 in your system (path) as well the super useful code julday from the PASSCAL software suite.  You can use the equivalent GIPSY executable
cal2day.
#!/bin/bash

#  Alberto M. Lopez  [Developed September 2, 2015]
#
#  Script for changing filename and headers from T02 format into
#  appropriate surveyed campaign station
#  This script assumes  will have always the same antenna -receiver combination
#  but does not use the same antenna height.  The line below that invokes teqc must be edited
#  to assign Name, Agency and Type of receiver.   Read the teqc manual for the different -O options.
#     USAGE:  Place all T02 files in a directory.  These are the files d/l'ed from the
#             receiver, which will have the Serial No. of the receiver, year, month and day.  The script will ask for the station name and the
#             antenna height used for the campaign.  The script will rename the file to the appropriate RINEX
#             convention (STATDOYS.YYX), and will fix the header to include the correct station name and height.
#             The script will generate directories for each day and will enter there to run teqc Quality Control
#             and it will generate the Summary QC file and all the QC plots.  You can run later teqcplot for sky plots and the like.
# A table will be generated that can be used for plotting the history of QC parameters.
#
#       UPDATES:
#       September 10, 2015:  Edited the original script to read from default filenames from NetR9
#       (e.g. 5038K70419201504220000.T02) in T02 format.  The default name is
#       serial number followed by year month day hour minutes session . T02  - This file is processed using
#       Trimble's proprietary decoder runpkr00.  If you have a different filename, you will have to edit the following variables in the loop below:
#          yr, yyr, mon and day so the cut command will work appropriately.
#
#
 echo 'Enter 4 Ch-ID of station in Caps'
 read stat
#
 echo -e “Enter antenna height in meters:"
 read anth
#
# Let's start the renaming loop:
 for f in *[0-9][A-Z][0-9]*
 do
        runpkr00 -demv $f
        yr=`echo $f | cut -c 11-14`
        yyr=`echo $f | cut -c 13-14`
        mon=`echo $f| cut -c 15-16`
        day=`echo $f| cut -c 17-18`
#        doy=`julday $mon $day $yr | grep Julian | awk '{print $3}’`
#if using julday (PASSCAL software)
doy=`cal2day $day $mon $yr | cut -c6-8`
#if using cal2day (GiPSy)
        echo $stat $yr $doy done
        base=`basename $f .T02`
        mv $base.eph $stat$doy"0."$yyr"N"
        teqc +C2 +nav $stat$doy"0."$yyr"N" -O.ag “Your Agency" -O.o “Operator’s Name" -O.mo $stat -O.mn $stat -O.rt “Type of receiver" -O.pe $anth 0.0 0.0 -tr d $base.dat > $stat$doy"0."$yyr"O"
        mkdir $doy
        mv $stat$doy* $doy/
done
mkdir RAW
mv *T02 RAW/
#
#  Now, let's do the QC
 for d in [0-9][0-9][0-9]
         do
                 cd $d
                 for f in $stat*O
                  do
                  teqc +qc +plot $f
                 done

Javier,


The .t02 file is a proprietary format that only Trimble knows how to read. You need to use Trimble’s software to convert the .t02 file to a .dat or ‘runpkr00’, and perhaps other ways provided by Trimble.

good afternoon


Could you tell me what is the syntax to convert a .t02 file from trimble to rinex?


Thank you
