Measurement Settings Suggestions

Would like to see measurement settings (Control and Boundary, Precise Topographic, Quick Topo, and Point Averaging) assigned to a white box or U1-U4 (click once and pick one from a list) on the action screen for quick access.
Also would like to be able to assign individual cogo routines as I choose from U1-U4.

Something similar to this is planned and will be available in the future.

I will request the cogo functions be made available for the user buttons.

Sean,
Until something new comes along, you can still take advantage of creating a Setup for various scenarios and then recall them as needed and noting that your fine tuned tweaks in Quick Setup always stay conjoined to that recalled Setup.

Curious as to how this is coming along? It has been kicked around for quite a while and this post is from a year ago.
We have the cogo but not the measurement settings yet.

It really transforms the way you will work with the LS and it is very useful for the new DPOS - Hybrid RTK process. Some shots you don't want to store raw data, such as quick topo shots. Some you will want raw data such as control and boundary. The quick setup options let you setup a topo profile without raw data recording and a control profile with raw data recording. A white box option shows you the current profile. When you press the white box, it takes you to the recall screen where you select the profile you want to use. It's really quick.

Well, I have been owning this equipment long enough, to figure out that I want a setting that will let me do alot. Kind of a default setting.
So, what I often use, is:
3 engines/3 engines Verify, with reset on.
25 confidence
25 consistency
60 epochs
120 seconds.

(Those using the general version, can substitute 600 epochs)

The way I use this is:
For a boundary point, out in the open, With distractions, and the like, it can run the whole 120 seconds.
Often, with this setting, I stop it at 120-200 epochs. If there are any obstructions, I press reset 2 times. Minor obstructions, that is.
If there are more obstructions, I let it run the whole 2+ minutes. If there are heavy obstructions, then I do it 2x. And, they agree by 0.05' of better, all the time.

Of course, I do other things, but this is a GOOD CORE setting. One that will get things solid, and not with a bad fix. Or, as they say, a non ambiguous Initialization.

When using this setting, for stakeout, I'd prefer that the "Compass swing freely" after coming to the end of the shot. So, if it says Go N49E 1.22', I can point the LS at the proper bearing, and set the marker. Then, (as is good practice) move up, on the SET monument, and re shoot it. Sometimes you have to beat the monument in, and move rocks etc.

What setting is your sort of DEFAULT setting?

With the above setting, you can quickly shoot a C/L, and stop it after 20 epochs, when there is 100% sky.

Please share what you consider to be your "Never fail" settings, for woods shots. I know I have been banging around with trying to break it... But, now, I'm headed the other way... What setting will NEVER fail.

Verify with resets, 2 min engines, confidence 25, consistency 25, validate with at least 2 engines for 300 seconds/5min, auto accept and repeat 2 times.

Have never stored a bad shot with these and have three shots to average to increase my relative precision.

Matthew, that would eat up a full 10 minutes. Maybe a little more.
Makes me wonder what PPS will do. That's enough time, to develop a pretty serious coordinate. 3x is over 15 mins.
Probably could be 20 mins, if it managed to start a few groups.
Thanks.
Makes me want to set mine out under a low pine forest, and cook all day, with various settings.
Just to continue the testing.
Time has a way of testing RTK GPS. As the sats "move" across the sky, the satellite geometry changes....

Yes 10-15 min per corner and can still get twice as much done in one day VS total station. The above settings equal redundancy and increased relative precision without sacrificing anything.

Can you get the same results faster? Maybe depending on location but why sacrifice good quality, repeatable data for a minute or two?

It seems to me that there are fundamentally 4 settings needed, The first 2 are for in the trees.
1.) HIGH certainty, low accuracy. Need the shot within .5 foot. DO NOT WANT it off by a foot or more. (Horizontal accuracy)
2.) HIGH certainty, HIGH accuracy. Need the shot within 0.05', but, a tenth is not going to bring down the house. (Horizontal accuracy)
3.) Setting for working in the clear. Lift and Tilt. Driveway shots. etc.
4.) PPS setting, for working where no radio is available.
I'm working on what settings to set all these up for.
Then, I need a setting, for modification. The one, I can assign anything wild to. For testing purposes.
I feel that it will become increasingly valuable to fully understand all the settings. And, that a fluent use of them is good.
Does anybody have a link, to a sky plot, or Graph plot, showing the periods of poor rms, in the day?
I kinda wish there was a link on this site to one.
Thanks for all your hard work.
