What about the fast static mode mentioned above, Opus can't return that great of a solution in that mode?
Dunno. I haven't done much with OPUS. I'm in learning mode.
Dave
My bad - in my mind, rapid static +/- 20 minutes, with added minutes depending on baseline lengths.
I did not know that a session of up to 2 hours is considered rapid by Opus.
Here's a close-up:
The Blue Light blinks once for each satellite it's receiving, then waits five seconds and blinks again. I was getting 10-12 satellites.
Operation is really simple: Turn it on, let it cook, turn it off.
I set it up over three different points, about 2-1/4 hours each, this morning. (I started about 2 a.m.)
Now I'll shoot some data over to OPUS. I might wait until morning, because some of the CORS sites download their info only once a day.
Dave
I think you made a fine choice dave.....just my 0.02 cents....
Mark has a good thing youtube about weeding out CORS stations unavailable and such. That's about all I know about.
I'm kind of "jones'ing" for some field time. I would like to see if my program can back it up.
Big E,
I did three 2-1/4 hour observations this morning, but I'm not having much luck with OPUS. I think it wants me to try again tomorrow. The problem is I can't find the files to re-send them. The X90 program has sent them deep into the bowels of my C: Drive. If I knew the names of the files, I could send out a search party, but alas...
Dave
Dave,
I believe the files still exist on the unit. I do the QC... Save to rinex (my specified folder)... And THEN send to OPUS. My files names contain the last 4 digits of the serial number, Julian date, and year.
Hope this helps,

David,
The files are still on the receiver, and they are in your download program. Look at your download program, and look at the dates of your observations. You can just highlight the observation, and resubmit using the download program. The observations default to the new project if I remember correctly.
I will be around the house/office tomorrow. Give me a call if you have a hard time finding the files. My numer is nine zero one eight three seven six two seven three.

Jimmy,
I found 'em! Sometimes you just have to click around until something happens:
Dave
Dan,
My observations get stored in a folder named "Rinex". According to the manual there are two files, a Nav and an Ob, whatever those are. Do you zip together the Nav and Ob to send to OPUS? The X90 program originally does something automatically to "reformat" before sending to OPUS. I'd like to understand what it's doing. What exactly is a "Rinex"?
Dave
E,
Where do I grab the XML? Do I have to select this option in the OPUS Submission Window?
Dave
Dan,
I'm just now reading about QC. What do you look for there? RMS? PDOP?
Dave
Jimmy,
How long do you have to wait before OPUS gives you a message like "You're cool, bro. Man, have we got some numbers for you!"
Dave
I believe you need to pick the "+ XML" option.
I don't know for sure actually being I've never submitted a OPUS job.
In my area it sometimes took more than 24 hours to get complete or adequate CORS data so I had to learn patience in submitting the data
Also OPUS-RS is very sensitive to CORS quality somehow because it does not use 3 or so CORS that are within 20km and goes to stations 45-80km away. As a result I maximize time and pay attention to the statistics and other info in the report. In the end I do get repeatable values. Alternatively I could probably make a rinex and post process myself from the nearer CORS.
I love the gadget though, as I am sure the problems I discuss are a result of the CORS/OPUS system and would also occur with any other receiver.

Thanks, Jerry. I'll wait a few days to see if OPUS gives me a more encouraging message. Then I might play with selecting different CORS Stations.
Dave
E,
I'm hoping tomorrow I'll get a more encouraging message from OPUS. I'll hit the +XML option and forward the results to you.
Dave
Can anybody tell me how this is different than a Leica Viva GPS? This unit seems like it just has one function: to run static. Can you do topo and construction staking with one of these?
This unit is specifically designed for static work only.
As far as differing from the Leice Viva... the list price on this receiver is currently $1880 including shipping to your door.
