CORS to Rover, no base

[Nate The Surveyor]

How do you process CORS to ROVER, with no base?
What happened is I thought I was done, so I took my base down... then as I started leaving the job, I SAW the power poles... I was supposed to tie those... So, I fired up the ROVER alone, set it to WAAS, and shot the poles, with 3' offsets.
How do you process those shots, as stand alone shots, against the CORS?

Thanks!

You can only currently do this through the online portal.

Well, I am trying to POST PROCESS against the CORS. Not real time... Like Dpos. Like a PPK.
It's actually there... sorta. It says

"Base-Rover+Base-CORS Processing+Rover CORS"

But, I only want PART of that, (It's the 3rd, or last option) I just want

"PPK Rover-CORS" Is that not in it? I somehow thought it was.

This is only possible if the point is part of a base station session.

How long did you locate the power poles and what accuracy do you need on them?

 

[Matthew D. Sibole]

If you had code float and had located them for 5-10 min you should be within 1-3' or so. I have seen it be as close as .3' but I had quite a bit of time on it.

 

[Nate The Surveyor]

3 min each. But, some were 1 min.

Accuracy? They are only shown for graphical purposes... 5' is fine.

What I got now, will do this job... But, I always WANT to be expanding my horizons. I somehow thought it could process "Rover to CORS". I can see the utility of it... especially as more CORS stations become available. (Or for those who have a CORS station nearby) Anyway, for this current job, I don't need it, but wanted to learn it... thinking it was hid somewhere.

This is just the question I was going to ask. I have not done the work yet, but this is in an area that I have been unsuccessful getting RTK radio to in the past. It's in heavy timber, but the point I need to tie is on the edge of an old clearcut, so I have relatively open sky just down in a hole where the radio won't get. Do I have to set the base up anyway? Then collect with the rover in standalone PPK mode?

 

[Matt Johnson]

Yes you need to set up the base unless you only want to process the data through web DPOS. Collect the point with any profile if you use the Active Post-Processing option.

 

[Bruce Dawson]

Okay folks, I collected the data for the point I spoke of above. I was in Standalone mode, with my T2 base running on a known coordinate. From the options screen I checked for the LS to collect GNSS data for the point, and also the base data. I collected for 30 minutes, then downloaded the data at the base.

Do I just DPOS the base data and the standalone point is processed as well?

 

[Nate The Surveyor]

Um... yes, if you have the right check box checked... Cors to Rover I believe. Look at all the options. It's there.

Okay Nate, I am not seeing that. What screen is it on?

Ah...I remember now! Okay, sending it to DPOS as we speak (type?).

Thanks!
