Importing OPUS

[Brandon Alred]

To start, I'm working with 1.15.

I've been looking at using the "Include from OPUS Output" option. When I try to do this, I only have the options of a .txt and a .opus files. 

The only outputs I have ever received from OPUS have been PDFs. Is there something I'm missing? Do I need to convert my PDF from OPUS to a .txt?

Hi Brandon,

I hadn't exercised the OPUS import in a while, so I just gave it a shot. This is with 1.15.0 also. I submitted a RINEX file to OPUS, selecting all default options (including Standard output as opposed to Extended, etc.) The solution came back as an email which I then copied and pasted into a text document (i.e., using notepad). I then used SALSA's Import --> Include from OPUS function and selected that file, and it imported/converted two POSG records. I was a little surprised there were two records, but looking at the OPUS results I see they provide solutions in two reference frames:

 REF FRAME: NAD_83(2011)(EPOCH:2010.0000)              ITRF2020 (EPOCH:2026.0013)

         X:      1112162.961(m)   0.005(m)           1112161.968(m)   0.005(m)
         Y:     -4842856.103(m)   0.004(m)          -4842854.663(m)   0.004(m)
         Z:      3985497.128(m)   0.008(m)           3985497.088(m)   0.008(m)

       LAT:   38 55 14.00729      0.008(m)        38 55 14.03940      0.008(m)
     E LON:  282 56  1.42422      0.004(m)       282 56  1.39740      0.004(m)
     W LON:   77  3 58.57578      0.004(m)        77  3 58.60260      0.004(m)
    EL HGT:           60.195(m)   0.005(m)                58.905(m)   0.005(m)
 ORTHO HGT:           92.186(m)   0.036(m) [NAVD88 (Computed using GEOID18)]

So SALSA imports both, and includes comments accordingly:

Assuming you're seeking maximum consistency with WGS 84, you would then deselect (or delete) the NAD_83 record and preserve the ITRF2020 record.

Let us know if this makes sense and you can reproduce these steps, or if you have further questions. Thanks,

Clark
