JMT and the Triumph 3NR

OPUS has a similar note for the triumph 2 and the triumph LS "Antenna with adapter"
but the drawings in the NGS antenna calibration data for the T-2 and LS clearly show
the ARP at the bottom of the receiver not the adapter. No drawing for the triumph-3NR.

You are right, I just checked the T-2 drawing. It looks like you need to use 2 meters as the antenna height.

Is "JAVTRIUMPH_2ANONE" the correct antenna to use when submitting a Triumph 3-NR file
to DEPOS? I do not see a Triumph 3-NR in the list.

You should use Auto with DPOS. If does not automatically choose JAVTRIUMPH_3NRA let us know. I just checked and it is in the list at https://app.javad.com/jca/#/dpos/upload.

I have the Triumph-3NR in the list in JMT.
When I download the file with Netview and send it to DEPOS using the antenna setting on AUTO DEPOS does not chose any antenna and the result appears to be about 6cm high. See report
I try to send the file directly from the phone, I get to the "what to do with file" window I do not have the " Process OPUS" or "Process DEPOS" options.

Is anyone sending files to dpos directly from JMT? I have not been able to, I get an error that there is no file, even though it’s downloaded from the receiver

I've tried to use JMT for the past hour or so. I'm waiting on support to enable my OAF for JPPP on the T3NR. Either way, JMT keeps dropping bluetooth connection with the T3NR??? This is frustrating. Is anyone else just repeatedly losing connections?
Mine will disconnect when my tablet screen goes to sleep, so I set mine not to time out. It draws more battery, but solved the connection issues

Has anybody noticed a problem with the ortho heights using the Triumph 3NR and JMT?
I took the T3NR and JMT out for a test drive Feb. 02, 2024 using the NYSNet network.
I visited 5 published benchmarks all had 2 OPUS shared observations all locations had very good
open sky. The marks were 2 to 3.5 miles from the base id:73. The T3NR and JMT obtained a fixed
solution quickly and held it well. The ortho heights on all 5 disks trended low by about 2 inches.
PID KV0805 JMT 0.16' low
PID DP7999 JMT 0.17' low
PID DP7894 JMT 0.21' low
PID KV0818 JMT 0.15' low
PID DM7186 JMT 0.12 low

Another test drive with the T3NR and JMT. Not very scientific but ok.
We collected 19 points using a Geomax Zenith 35 with Carlson Surv PC on Leica Smartnet (IMAX).
After each point was collected we immediately collected the same points with the Triumph 3NR
using JMT on the New York state network (RTCM3 FULL MSM NEAR). Multi engine, all points fixed
on 3 or 4 engines. Smartnet and the New York State Network share the same CORS.
The differences on all points were reasonable horizontal and vertical. Five points were collected
about a year using a Septentrio NR3 and Carlson Surv PC. The differences between the 3 systems
were Reasonable.

Not a problem. those seem to all be within published tolerance of the network. If you need to match closer you need to use your own local base.

I am not feeling warm and fuzzy about the ortho heights I get from DEPOS with the Triumph 3NR.
I do not see a specific antenna listed in DEPOS for the Triumph 3NR. I did a 2 hour occupation on
a published monument and processed in DEPOS with the antenna set to auto. The horizontal coordinates
look hot. The ortho height is 0.21 feet high compared to the height on the NGS data sheet and the height
from an OPUS shared solution. No antenna type shows on the DEPOS report

Without applying the 'adapter', the TRIUMPH_2A NONE vs a TRIUMPH-3NRA NONE APC offset difference is ~7mm (~0.023USft)
