My LS is still getting use to this as he has been a loop traverse guy and compass rule.
I still see this a lot, and I'm not a fan personally. Does it work well enough for most people most of the time? Sure. Can't deny that.
Me? I want everything double determined at a minimum- be it from two different total station control points, total station + GNSS, or double occupied GNSS (although this probably isn't the case if we're working in downtown LA... can be hit and miss). 95/100 times you won't see much of a difference. 4/100 times you'll see a difference but it won't have a significant impact. It's that 1/100 that I try to account for when doing control- any type of control, really. You never know when you're recycling control/monuments to use in another project.
@steinhoff Is downtown LA Lower Alabama or Louisiana or Los Angeles. I appreciate the info. I have not done any stop n go since the USMC days. Glad you rattled my brain on that. I had not even considered that as an option. Might have to use that as my next training session. I am always trying to train on the options. So the crews have all the tools in the toolbox they might need. You just never know what situations might call for a different approach for sure.

Downtown Los Angeles

If our crews are running RTK then I have them use an RTK-logging style by default. Additional backcheck option (or in this case the opportunity to process your rover against an additional base) for free.
@steinhoff What epoch do you use at base and rover. I do the whole rtk and logging I remember that from the 90,s. A lot of what we do because of no cell is the whole opus. So i log at base for that while the map and do whatever so they can be productive. I will have to try the stop and go for sure. Today i am dealing with some very noisy data in static. Geezers its as if some of the cors station are taped to a dancer. To close to a military base I imagine.
What epoch do you use at base and rover.
Usually 1 second epochs. 10-15 degree elevation mask for RTK base and rover, 0 elevation mask for static. Now will the crew remember to make sure all constellations are enabled...? I dunno, but let's pray just in case.
@steinhoff nice. Why a 0 elevation mask at rover or is that a typo. And supposed to be 10. I have been burning the late night oil figuring out TBC baseline processor.i am so use to methodically processing sessions and independent dependent baselines it has taken some getting use to. I watched a couple partial videos on youtube and power hour. But nothing like the old days of telling the software exactly what and when you want to process. I did a all at once then manually chose some and I didn’t see much difference has the whole independent s dependent mine set gone away because technology has just become that good. Or does one still do this in todays off the shelf software. I been drawing circles and poly lines to mark them visually or am I missing anything that will mark them for me. And let me know i have process two baselines other than having to select them to see.
Why a 0 elevation mask at rover or is that a typo.
For a static-only base? I collect at 0 elevation mask and THEN process at 10-15 degrees. Why not? Plenty of storage space.
For something like an RTK base or an RTK rover? Yeah, 10-15 degrees like I noted above since you're working on the fly.

Given that commercial programs like TBC utilize a baseline processor instead of a session processor like PAGES, all baselines are arguably independent.
@steinhoff I see the thinking in that. I have always never closed a triangle or loop at any common time frame as I built networks. I reckon if you have redundant observations it would show any blunders anyway. I have been playing around with both ways all everything and manually choosing and so far not a lot of difference. Hard to break old habits and how i was taught for sure. TBC is fairly fast time wise for sure. I will have to read up more on all of this for sure.
