The round table

[Adam]

I think there are couple scenario's that will happen.

1. Folks with a good rtn and rtpk may not ever DPOS, unless they have multiple base locations and are concerned about vertical.
2. Folks with rtpk but without a good rtn will always dpos the base but not all raw gnss points because they already have rtpk.
3. Folks without an rtn or rtpk should always use DPOS.

 

[Jim Frame]

3. Folks without an rtn or rtpk should always use DPOS.

Or OPUS Projects when you have multiple bases. I prefer this approach because the results are from a non-proprietary processing tool that's recognized by public agencies, notably FEMA.

 

[Matthew D. Sibole]

I turn off “process all process all points with raw Gnss data” when I submit to DPOS.

I start with a RTN base position and if it is a project that will be a long one or I expect to use that base point for multiple projects I will send the base point to DPOS.

 

[Matt Johnson]

DPOS Base/Rover processing should not be used with RTPK. It will overwrite the RTPK coordinates and the RTPK verification will be lost.

GPS in inches:

 

[Nate The Surveyor]

How does it work? IMU, (Inertial Measurement System) tilt sensor, and non-magnetic direction indicator, to determine direction of tilt.
We did not get to be surveyors, without a fully curious system at work in us.
In fact, insatiable curiosity is a character trait that I consider to be one of the most desired traits of a surveyor.
Creativity, and willingness to look at subject matters from different points of view are all desirable, but curiosity will do many things that nothing else will.
Anyhow, how does that thing work?
Thanks,
Nate

Using LS+ / T-3. Setup T-3 on nail. Start job on Autonomous. do the days work. Go back and want to use the same nail for base. Do you DPOS the autonomous base for base/rover setup or does that change of all the shots you have done already. Mike

 

[Matthew D. Sibole]

You DPOS after the first day. That will move your base from the autonomous position to actual state plane. The next day you go out your recall the previous base point which will have been adjusted to state plane so everything will be relative to that position.

DPOS adjusts the base and every point that is shot from the base to state plane.

 

[Michael]

Thank you Matthew. Thought that was so, but wanted to confirm.

 

[Nate The Surveyor]

Time separation between multiple shots on same point.
I'm walking down a fence row, taking shots on various things, and survey marks. I take shots as I go. Get to the end, and re do shots on the way back.
The LS is already programmed to let you know there is a previous coord, a few hundredths away.
It'd be nice if we had the ability to know direction, and dist to it automatically. And, copy or use prev point description.
It could do a cluster detect. And, be able to copy any prev desc. And, put the little cluster on the screen, at some scale, and make a mark where the avg of cluster would land. Just to slick up the field analysis part.

So, what about the rumor that there is a major release coming before Christmas?
What's it got in it? Any major changes?
Is the rumor true?
And if so, what can we expect in the way of changes?
Thanks

Nate; just curious, which other brands are you referring to?

I believe that SEVERAL brands of GPS are better than Javad, or nearly better, when comparing the T-2, Radio, and LS, Like I have. (Non LS Plus). I keep my ear on the road. By better, I mean come up with the right answer, faster.

Sean, the difference between the Plus and the standard really is an apples and oranges comparison.

 

[Nate The Surveyor]

Well, a Trimble r10 is close to equal to a non plus LS, running with t2 on base.
I've got a friend who describes the igage to me as being close as well. These comparisons are, as Adam says apples to oranges, because the t2 is limited in constellations. USA, and Russian, and piece of the others. The t3 is a full multi-constellation reciever.
So, the t2 and LS regular is going to be not quite as good as a full constellation system should come as no surprise.
Now, I will say I like my t3 and LS plus. Is it worth it? Well, if you work in big sky country, it probably won't matter alot. Or in a wide open plain state. But, if you go where there's nearly no sunshine.... Then the LS plus and t3 shine.

Adam thanks, that first message reply was in error dont know why it wasn,t deleted.. I know that the 2 are very different

Nate I probably should have been more specific,
The question is about the best Javad has to offer vs the best "they" have to offer.
All things considered I am not seeing any others even close yet. After Using Javad and then trying to go backwards to another make?? I would be willing to bet no one on this forum would even consider it
I have had guys tell me about Carlson working well in the woods but is it even on the same playing field as Javad?
I doubt it.

Dumb I have to have a disclaimer but employer is a little picky...

Disclaimer: The following is personal opinion and should not be considered as being associated with my employer or position. Please refrain from repeating or sharing to other platforms.

I do not have experience with Carlson or any other lower cost systems so cannot comment about them, but big T's R10s/R12s I can comment on.

I can't say I wanted to switch but I changed state/office and they are R10/R12 users in Idaho. I currently supervise so no daily use since 2019, but I am responsible for knowing the equipment nonetheless. I have not had the pleasure of using the LS+/T3 combo, I only have used the LS/T2 combo. Certain models of R10s are multi constellation capable if the option is paid. From 2016 to 2019 I was still in the field using R10s and I could make it work but just not the same as my previous experience with LS/T2. The R12s are also multi constellation but use a multi solution check utilizing 1 engine but 2 separate satellite combos. We now have a R12i set that has been used for part of this last summer and 2 sets almost ready to go out to crews. The crew with the R12i set loves it but they are forever T users that have never used anything but big T. I went out with the R12i crew for a week and personally I was disappointed especially considering the cost. The fact I have not used Javad since 2016 and have not had a chance to play with the LS+/T3 combo but was still disappointed says an awful lot to me. Of course the R12s should have an advantage over the LS/T2 set, but from what I have read about LS+/T3 combo I would guess Javad still has the edge. I have to be careful about promoting but my personal choice will always be Javad. Maybe someday I will get opportunity to switch back....place sad crying emoticon here! LOL

Several Javad users have contacted me, about upgrading to the latest Javad gear.
Here is a general answer, for those of you who are using T-2, and LS (minus or regular) as opposed to PLUS.
Here is the upgrade path:

1.) Buy a T-3 first. I also recommend that you get cell modem with it. Reason for Cell modem is: With the T-2, and REGULAR LS, and a Radio, you are sending packets from BASE to ROVER than are 8 ounces each. (Figure of speech) With the T-3, you are sending packets over the radio that are 16-22 ounces each. Since the data packets are BIGGER, and we have been narrow banded, you need a BETTER device to send data via BASE to ROVER. IF we could get a radio, to work on 2 or 4 frequencies at once, this could potentially solve it. But, that is not available.
2.) Then Get the LS Plus upgrade.
Comment on the 4 engine system, It SEEMS to focus on only one engine to maintain lock. Then, adds the rest. This allows the LS+ to get proper fix, without pressing fix, about 90% of the time. I always press start, to CONFIRM, but it's real fast, and good, most of the time, without pressing start.
IF you cannot get cell modem for coms, you will need External Antenna on the LS alot, and you will want the BASE radio antenna as HIGH as you can get it.

OF course, you can just get RTPK upgrade, ($1000 was price last I checked) and keep running the LS-T2 combo. This will allow you to do alot, with your old gear. HOWEVER, you should consider that VERSION 4.0 has already been released, into PRE-release. And, the BEST parts of software is usually designed for the latest version of the hardware. So, obsolete-ism, is un avoidable.

In short, the LS + and T-3 is dynamite.
