Javad DPOS and Triumph 1/LS

[Robert P Stenerson]

Okay, I'm back in the office now, so I can upload a couple of screen shots for my original questions, and thanks everyone the great support.
Here's the first page of topo shots, and I don't see the little circles pointing to circles Shawn mentioned. The second screen shot is my last page where my BaseRPS is highlighted.
And the third one is is from going into the DPOS screen from COGO, and it shows the base was adjusted, but I'm not sure about the associated topo shots?

I guess I'm a little confused by the automatic part of the DPOS process with LS, if DPOS needs about 24hrs a la OPUS, how can it use my downloaded file so soon after, i.e. as soon as I shut down and download the Base file?

Missing the third one Rory.

Don't confuse automatic with instant. The process can be performed automatically using the settings Matt shows above. But it isn't instant. The file is downloaded from your base to the LS. Then when the LS has internet access it begins to attempt to upload the base file to the DPOS server. DPOS checks for data availability. If it isn't ready, the process starts again, until there is data available. All of this is done without user intervention, hence "automatic". But it does require usually waiting until the next morning for ties to IGS stations (CORS) to be processed. Once the results are received from DPOS, the user can set the LS to automatically adjust all of the rover points to the new base coordinate (as Matt shows above). Or you can turn off the automatic settings, send the file to DPOS by highlighting the file and pressing "DPOS" then pressing "ADJUST" when the results come back.

Arggh! I am very confused <g>, and I didn't get that third screen shot uploaded as mentioned above, here it is

 

[Robert P Stenerson]

Hi Shawn,

I am 99% sure that my settings matched Matt's example from above. How do I know if my points did get adjusted? My topo points listing still has no little circles pointing to little circles like you mentioned previously.

Thanks,
Rory

 

[Shawn Billings]

On the points list, highlight the point 1000, then tap the blue field on the right side. You should see a "SHIFT" note with a direction, distance and vertical difference.

 

[Robert P Stenerson]

Hmmm, okay here's what I got

 

[Shawn Billings]

I was wrong about the shift icon next to the points. This apparently only applies with the base coordinates are manually edited or Reverse shift is used. My apologies.

What I describe above (highlight point) tap blue field will show you the statistics for the point which will include the shift. You can also scroll down the blue field and you will see the Survey Shifted and Survey Origin as well as Base Station Shifted and Base Station Origin coordinates.

 

[Shawn Billings]

Pick a different point. I see that you go from 1000 to 1046, that's two more than 45. Did you shoot a couple of points from a different base session?

 

[Shawn Billings]

DPOS only adjusts points in that base session.

 

[Robert P Stenerson]

Since you're online could you do a remote session with me so you can see what I'm seeing or show me this scrolling down, I can't scroll down

 

[Shawn Billings]

yes. what's your password?

 

[Robert P Stenerson]

Ahhh I can see it with point 1024. Great thanks!!!

I think the shift symbol that we use to have besides the points is broken now.

You can scroll down on the blue field on the right.

 

[Robert P Stenerson]

I just sent my LS password to your phone, SMS

 

[Robert P Stenerson]

This is cool, love the remote assistance

 

[Robert P Stenerson]

So are you now just highlighting the blue area next to RPSBase1 and I can see Base (new adjusted values), and the Old (the autonomous position?)

 

[Shawn Billings]

I'm guessing that point 1000 must have come from a previous base session. I see that you have several points that look like they were base points (maybe a couple of false starts).

When you look at the DPOS screen press the blue field and you'll see statistics about the DPOS solution.



Here you can see that there was only data from one CORS site. You had a nice long file, in excess of 4 hours. This should give you a very good position, but notice the sigma values are kind of high. Wait a bit longer and submit this file again. With more data you'll get a better solution. I recommend checking the results of the DPOS solution this way before accepting the results.

 

[Robert P Stenerson]

Okay, great info, I learned alot. Surprising about the CORS stations considering I was about 2 miles from PSU1. Now if I resubmit (not sure how I would do this other than downloading the GNSS data file and sending it to DPOS via the website) this base to DPOS say this weekend will it readjust all the points taken with it?

 

[Shawn Billings]

Try it out now. Highlight the file name in DPOS, then hit "DPOS". It will ask if you want to resend the file to DPOS. Answer yes. When the result comes back you can hit adjust and it will apply the newest adjustment. It will forget the current adjustment you have. It will always remember your original autonomous based coordinates and just keep apply new adjustments to the original coordinates.
