Data Transfer & Conversion Workflow
The Trimble Data Transfer tool sometimes has trouble transferring files from the receiver when using a USB to serial converter. I’ve had better luck using the rutils package.
In this example, I ran the
rutils on a Windows XP VM, and
teqc natively on a mac.
- Use rfile to transfer the raw observation data from the receiver
- Use runpkr00 to convert the raw file into a trimble dat file
- use teqc to convert the trimble dat file to RINEX 2
1. List files
rfile -DCOM2 -B57600 -Pn --rtscts -N
--rtscts disables RTS/CTS flow control. Like most FTDI based converters, the one I used does not have any of the hardware flow control signals connected.
This will produce the following output:
RC REMOTE CONTROL, v2.55 WIN32 (Jan 16 2004) Copyright (c) 1993-2001 Trimble Navigation Limited. All rights reserved. rfile, 2.102 Storing new device file name (COM2). Setting COM2 to 57600,NONE,8,1.

Use the number from the INDEX column to select the file to transfer. In this example, I want
41131640, which has index
rfile -DCOM2 -B57600 -Pn --rtscts -F -I019,41131640
This will transfer the file to your PC. In my case it produced a lot of errors and retries, but was ultimately successful. It seems to struggle regardless of baud rate.
Now, convert the
.r00 file to a
runpkr00 -d 41131640.r00 41131640.dat
And then use teqc to convert the
.dat file into a RINEX 2 file. In this case, I’m using a receiver with stock firmware, so it thinks it’s 2001 when it’s actually 2021, so I have to tell teqc what week it is.
teqc -tr d -week 2142 41131640.dat > 41131640.21o
And you’re done!
