You would need to use the "Multi Select" option found in the Context Menu of the Files screen. Whole folders can also be copied and screenshots can also be exported with "Archive Current Project".

thanks

Nate, your screenshots are not showing abnormal interference. If you look at the screenshots of the points you could see the inference levels while the points were being collected.

I don't know that the interference is excessive, but there is clearly interference in the L1 band and L5 shows spikes in the blue graph (the receiver's countermeasure to interference). It might not mean much, but the graphs are not exactly textbook. Nate and I spoke a bit about it, I would also recommend observing a bit longer to see if the interference is intermittent as Nate suggested. Perhaps a minute or more to acquire a better idea of the interference. Currently the default is 10 seconds.

The shot i posted was 50" long... I think!

Nate any luck getting the screenshot off the LS yet? All you need to do is Export>Project Archive File Format and use theses setting and post the zip file in here.

I found the problem.
I use HIXON Prism poles. They are very good poles. The bubbles in them stay adjusted, and, often only need MINOR adjustment every year or two. To check one, extend it, tie the top to something, and plumb it, and spin it.
This is the CORRECT look of one of these prism pole, bubbles: This is the BAD BUBBLE. The bubble was TOO BIG. It was hard to plumb the rod, but, I took my time. My son said, "But the pole is not plumb". I checked it with the PLUMB BOB. Sure enough. Bad pole bubble. So, most of this 0.25' is from my bad pole. So, I apologize. I have had my HIXON poles perform so well, for so long, that I did not adequately check them. How I found it, is I set the pole up in the yard, and plumbed it, and then moved the top around, to see how much it affected the bubble, It could move a tenth, and NOT CHANGE THE BUBBLE substantially.

And, having been through many things, with the JAVAD, that worked one day, and not the next, I assumed.

So, I'm sorry. I think it has been my pole all along. The thing is, when the pole is cool, it can be adjusted, and indexed, and set pretty good.
I think the bubble failure was heat related. I did notice the bubble was growing in size... but now I feel better. I'm pretty sure I have it nailed down.

And, on the failure to BASE to ROVER process, it was ALSO my fault.
I did not have the box checked "Process all points with GNSS RAW".

I had BASE PROCESSING only, or Base processing + Base Shift checked. I did not know that "Process all points with GNSS RAW" had to be checked.

Growing pains.

Thanks for all your patience, and help.

I will add, it is my ROVER pole, that was bad.

Another thing... The pole could be adjusted PERFECTLY in the morning. When the heat got on it, the bubble would move. It was making as much as 0.15' error, at 6' high.
Part of that bubble had separated, and was reacting to the heat.
GLAD it is not the LS, or Javad equipment.

Nate, your scenario is why I like to put a second bubble on my poles. One at the normal location and one about 2ft up from the bottom of the pole. You can compare the two and know if one is out it's time to adjust. Plus if you are doing stake out you can place the pole on top of the stake and still see the bottom bubble.

 

[Nate The Surveyor]

The stinking thing, is I could adjust it good, and then, when it got hot, it would move.
Faulty Bubble.
I used to carry one of these: http://www.ebay.com/itm/Sokkia-Rod-...560892?hash=item19f7527dbc:g:TxEAAOSwD0lUbrmH
But, one of us broke the bubble.
It was just for a quick check.
Maybe I get another.....
