I guess this could also go under humor 🙂
I came in to the office this morning, booted up my computer and opened Outlook. I received 35-40 emails from OPUS for files from 2008-2009. Are these time bandit files? Has anybody else experienced this?

What was the process date?
BTW, did they use the finsl otbit?

If you have the extended output then you will notice a NEW (non NAVD-88) computer orthometric height.
** Orthometric Heights Above Future Geopotential Datum.
Prototype orthometric heights are now being made available as a precursor to the completion of GRAV-D and the replacement of NAVD 88 with a new geopotential reference system. The following height reflects the current best estimate of the true orthometric height, based on the existing gravimetric geoid model. This height is subject to change as data and modeling for the gravimetric geoid change throughout the lifetime of the GRAV-D project, or as new realizations of the ITRF are adopted. However, at the completion of GRAV-D, these heights will supersede the NAVD 88 heights

Looks like the ones sent to me were all OPUS-DB stations that I created but I'll have to check them later. We have to topo jobs to do this morning.

I believe these were stations that were submitted to OPUS-DB as well.
I checked three quickly and they were all OPUS-DB stations. The reports sent are in the latest NAD-83(2011) and there are no geoid heights computed. But there are these new grav-d orthometric heights. I'll have to copy and take these home tonight for a bit of study.
Stop the world. I want to get off.
And I'm still trying to work my head around relative versus absolute antenna files. (Antinfo versus Antex). I have a lot of catching up to do now.

i got two opus results yesterday as well. haven't actually used it in about three weeks. maybe old data files are rattling through the pipeline
Yup...I got one this morning too (from 2008).
It is the ONLY OPUS_DB submission file that I have as yet submitted, so I think that the OPUS_DB "connection" is probably the answer.
It seems to me that I heard [somewhere] that the NGS was going to "update" the existing OPUS_DB [database] to NAD83(2011) Epoch 2010.0000 at some point, MAYBE this is the beginning (or end) of that process.

I received about 30 or so yesterday evening. We have submitted well over 200, probably close to 300 stations to DB, mostly around USACE projects.
