Shawn, our next experiment is totally clear for me now. As horizontal is not a problem than put t1 and t2 next each other on POST station. Evaluate heights above POST. Log data at both receivers. Than send to process.
Javad DPOS and Triumph 1/LS

I will have data ready for you when you arrive to work on Monday.
Alexey, one of the OPUS observations I had was off a considerable amount horizontally. Did you notice this too when you processed?

I will test with LS and T2 tommorrow too.
I will process data Monday. In a case of OPUS/DPOS discrepancy I can usually find something incorrect inside raw data. For example, third file sent by John includes events for antenna height update inside. OPUS declines process. DPOS processed somehow but the result was suspicious.
Alexey,
I am not sure why the third file I sent contained the antenna height change. It is possible that at some point during that day, I utilized base rover setup, and did not "follow through". To avoid confusion, just ignore my third file.
I will be running again Saturday and Sunday. The only receivers I have are the LS and T2. I will mount them at common height for recording.

Don't worry, John. I have splitted that file and processed it well. LS in a couple with T2 will be OK.
Triumph-1: Vertical Height 0.100m

Triumph-2: Vertical Height 0.100m + 0.025m Adapter = 0.125m
https://drive.google.com/file/d/0BzRuWb4iNIVFNTRMZDJtMWNzQTg/view?usp=sharing
The Triumph-1 was positioned directly over station POST at a height of 10cm, while the Triumph-2 was on the opposite end of a 20cm bar at a height of 12.5cm. Files are nearly identical in length, started and stopped at the same time. The bar is oriented generally South to North with the Triumph-1 on the South and the Triumph-2 on the North. The files are approximately 8 hours at a rate of 10 seconds.
I ran a test of the files through OPUS and DPOS. OPUS selected different CORS sites for the files even though they were recorded at the same time and within 20cm of each other. I'm sure you already would do this, but I would recommend forcing OPUS to use a particular set of CORS for both files to remove variables between the solutions.

Alexey,
Attached is the data from my T2, and my LS. They were mounted on tripod, using a tribrach with a horizontal beam. No adapters were used at all. Estimated leveling inaccuracy of beam does not exceed 2mm. Sorry no picture.
The files beginning with the name "log" are from the T2. The files beginning with a number are from the LS.
I have not yet processed these myself.

Got it.
Alexey. I used a caliper and determined the height is actually 97mm, not 100. It's not a lot of difference, but it's definitely 3mm short of 100mm. So the Triumph-1 is 97 and the Triumph-2 is 97+25 = 122mm
I could not get OPUS to process the file from the LS.
The internal format of the raw file you submitted to OPUS could
not be converted to RINEX by NGS and is therefore not supported
by OPUS!
Please convert the raw file to RINEX before uploading or contact
your receiver manufacturer for an alternative solution
I experienced the same as Adam. My LS OPUS submissions were rejected. T2 returned fine.
OPUS accepts RINEXed with jps2rin files (disable events/occupations).
Updated
Alexey, have you tried selecting the same base stations OPUS is processing with and also only processing with GPS? This would make the results more comparable.
DPOS selects the same stations as OPUS does, but 2 stations extra. I did not remove GLONASS and sent files as is.
