Base Guard

[James Suttles]

Base Guard in LS - LS, seems to be implemented, but I think it may have an issue. The base has not moved, but I am getting lots of warnings about it. I have attached a screenshot to show what I am seeing. The base is on the correct point, and has not moved. I have gotten this message since I installed the latest version of Pre-release

This maybe something that needs to be checked by the team.

Thanks

If it persists, you can turn off the warning in the "Warning" hard button screen.

 

[James Suttles]

Thanks. Will do. Wasn't sure if this was something you guys needed to know or not.

Yes. Thanks for reporting. 132 MG is a lot of motion. We will review.
Are you sure that it was not subject to any vibration? Even loud sounds or a truck running near you?

Thanks for posting those screen shots after we spoke Doug. There has been a number of really nice improvements lately. This is one of them.

Javad, thanks for implementing base gaurd with the LS base.

How long has It been since you calibrated the compass and tilt on the LS base Doug? It may be worth getting a fresh calibration with this update.

 

[Adam]

Javad, notice the tilt of 358.2 degrees. Seems odd.

Does it not mean -1.8 degree? I don't remember our convention.

 

[Adam]

I haven't used base gaurd in a long time but I dont remember it displaying that way. I thought It displayed + or - from 0.

 

[Shawn Billings]

I think it's direction, not tilt.

 

[James Suttles]

Its been about 4 weeks since calibration. There was not any vibration or loud noise, at the base site. It was a wide open field about 80 ft away from a secondary roadway.

Right Tilt should not be such huge. Looks like unit was felt down and hit the ground to generate such parameters.

James, did you set the base at the point and then configured and start base?

 

[James Suttles]

It was configured and then set up onto a 2m fixed height tripod. Does it need to be configured after its placed on the 2m Tripod?

It should not be started with the Start button until it is on the tripod.

 

[James Suttles]

That is what we did, I double checked, we did not tell it to start until it was on the tripod and everything was level. We have adjusted the tripod bubble, I will re calibrate the level in the LS, before we start the next project. Attached is an image using the same base point, today. If its something we are doing incorrectly, we will try to correct it.

We will start a new project this afternoon, I will report if the problem persist.

7 inches? Only Architects and Whores use inches!

@Eugene Aksyonov I have still been seeing large values with base gaurd when using the LS as a base. Can this be investigated a little more?

Adam, I never check the ability of TR-LS to support "Who moved my base". But if messages are coming it means we have a chance to make it work. What I see now - is not usable. Tilt of 187 or 358 degree is kind of unrealistic values. 838mG is equal to short but strong side kick, which is not the case I believe. Finally, 18cm doesn't seem to be correct.
And yes, calibrated Levels and compass should be used.

It works correctly sometimes, other times it gives the wild values. I always have the LS stable and on point when I start it. Yes, my tilt sensors and compass are calibrated.

Probably we have read non filtered values from accelerometers that may explain lilt and G values, but distance is measured by position vector from point to point. I will check for this issue in bag tracking backlog.
