Yeah, Bell telephone had the technology; just never got it as integrated as Apple and Samsung:)

I only see LS product presentations with its short pole. How can one operate its screen and buttons when the receiver is up high using a 4.65m Seco pole, for instance? Does this mean that using long polse is a thing of the past for Javad receivers? Or does this mean there is a an optional some sort of secondary screen?

How about F2F features? Offset routines?

Is Javad definitely much cheaper that Trimble or Leica?

Thank you.

With the 6 RTK engines and the Verify/Validate feature in J-Field, does this mean that measuring/storing points could be much more difficult? How about for topo application wherein I just want <=2" accuracy? Is it possible to set some values in the receiver to be more lenient and accept/store points of 2" accuracy?

Thank you.

Im at day's end. Typing on phone.
You ask many questions.
I only take on one of them.
Short pole.
I usually run mine on a 12' Hixon pole.
My pole is almost all day at 5.1' to the bottom of the LS..
It simply does it all down there.
If i want to take a shot at 12' i set a 5 or 10 second delay. There is a flashlight built into the bottom of the LS. It blinks, in certian patterns, depending on what the ls is doing. It tells you when it's got the shot. Also, you can wear a bluetooth ear piece, and you can hear it.
Also, you can run the LS from a cell phone, remotely.
Quite bluntly, it's got the power, so it does it all down low.
Occasionally there are advantages to going up. Building corners. Real deep holes. But if you begin to use one, you will find that going tall is simply not needed, for most shots.
Today i shot a corner 1x, at 5.1' and 2x at 6.1'. I have a mark on the pole for 6.1'. I'm tall. So this works. I wanted a change in multipath... So i changed it. All three shots were within a tenth. The 1st one showed a larger ellipse, than i wanted. So, I went up a foot, and tightened up the position.

Amadog,

The field to finish is actually performed and displayed on the Triumph LS itself. All line work and symbols, export as an Autocad drawing, or DXF. Of course this in addition to the many other formats. The lines are 2d and 3d, and you can add a prefix to the 3d layer name if desired.

The cross sectioning works great for me. I can be running a dozen lines at once, and never have to push a button. If I do push a button, I can very easily control the auto sequence of the items in a cross section.

I really like it a lot.

Great info guys.

Javad is one of my considerations for my next RTK kit.

Thank you.

Yes, I will occasionally widen the confidence gaurd setting for rough topo in canopy. During verification new groups are made if they fall outside of the confidence gaurd of the current group. So if I'm looking for 1' horizontal and .5' vertical then I will enter these values and any epochs within this tolerance will count up and once it hits the required confidence for this group it will procede to the second phase where all epochs outside of the confidence gaurd are rejected. Very nice for rough topo in canopy.

Is Javad capable of processing point position using correction from two or more sources like base + CORS or multiple base units?

Thank you guys.

As I am a Civil 3D user, I need to create an environment in LS wherein it promotes automation of lineworks/figure creation in Civil 3D. This is somehow related to coding/linework system in LS. Can this be done?

Thank you.

This is not something that is possible right now. Hopefully in the future it will be.

Yes but you pay a price in terms of time. I used to think the R10 was worse than (or at least no better than) the R8 model 3, and I still feel that way about the first few sets I ever had experience with's firmware. With recent firmware upgrades and additional satellite launches we can get almost 100% of our locations in the woods with the R10s. Sometimes one shot may take 20 minutes, and you may have to be happy with swing ties, but given the terrain in western Kentucky and southern WV I can guarantee that you won't locate the points any better via traverse. I wouldn't want just any field hand trying to accomplish it with the spray and pray method, it takes someone willing to put the stink eye on the results in the field.

I will say that if I was a solo or smaller operation I would pull the trigger on the LS in a heartbeat. It is basically an R10 econobox. The biggest advantage of the LS is the point occupancy QA/QC routines it has built in, and the biggest advantage of the R10 is the overall data collection and entire Trimble ecosystem.

Plumb Bill, I wish I'd said that. (I could not, because I don't know anything about the R10 and R8 systems....) But from what I see, and read, I think you are on the right track.
There are a few other things that really smooth up the LS.
One of them is DPOS. It corrects up autonomous base positions, to be on pure SPC, in a few minutes. All the sideshots from that base, get moved with it. Essentially, all jobs now are SPC.
Another is that you CAN work a local system, or LDP with ease. You can carry coords from one job, to another, and they are on the same datam. Or, with LDP's, on the same UNDERLYING datum.

O well.

And. I agree, the "Entire Trimble Eco system" is hard to abandon, when you have so much stuff that HAS to work together.

Actually we can process your base and Cors stations but it is post processed not real time.

I think most of the manufactures are going the "eco system" route. I went with an R10 because topcon was making the change to all or nothing. It's frustrating but I understand from a business standpoint of why they are doing it.
On the other hand if you consider the Javad "tip" locator. Not a good idea in my opinion to require it to only work with the LS, maybe the technology isn't there yet but I would've bought day one if it didn't only work with javad

Just because a system "Goes Fixed under canopy" is no indication of when the integers are wrong. Multiple fixes, under canopy, over a period of time, are necessary, to be confident, that it is not a bad init.

Oops...I meant eastern Kentucky.

You mean real time from one reference and rest is post processing? My intention here is for stakeout work.

Thank you.

Have another question here.

Is it possible using the LS to perform post processing in the field if I do static survey for example?

Thank you.

Amdomag,

Yes the LS can process your static vectors while in the field. Internet connection required, as processing runs on cloud server. It only takes a few minutes to do.

Real time from your base and post processed from your base and Cors.
