Yes, and make sure to turn on the "GNSS point averaging". Rather than a simple averaging of the coordinates from multiple observations, (to my understanding) this is a weighted average using vector data, based on pdop/ rms etc/ at the time of the measurement. Check out this video:

I start with truth. I want that box to tell me the truth.
Nice easy cogo is second.
Third, is good hardware.

Boxes cannot tell you the truth.?ÿ I can tell you where to find truth, but then some will accuse me of talking about religion.?ÿ
Any modern box can give you enough evidence of your location to do surveying.
Workflow is what makes money. If you are a sole proprietor, I suppose it doesn't matter. But if you have to train anyone, or need to have multiple crews work together smoothly, or use a total station with the same software, then you start with software.
I have used both and here is my experience.?ÿ
?ÿ
1. The BRX7 is absolutely worth every penny and as accurate in tree cover as the JAVAD. I got fixed faster and it was a faster unit. It is the Carlson environment of software and as we all know or should know, Carlson is the way to go if you are a pure surveying shop. What I didn't like is that I can't get into the nuts and bolts of a shot. In other words, I only know that it is fixed and that it stored a shot. There is no comparison to other GPS methods incorporated like the Javad.
2. Overall I prefer the Javad for a couple of reasons. THe first is I get to see the metadata of each property corner. That doesn't sound like a big deal, but Javad got me hooked to reviewing the data, the RTK fix vs. the PPK shot, the comparison screen, the occupy time, etc. etc. Javad does an excellent job at presenting all of the data and giving the PLS confidence in the solution. I also prefer the Javad because they are the only ones on the market that I know of where you can broadcast the base corrections without huge upgrades in software or hardware. I simply have my based talking to and through a static IP address MIFI card and the Rover gets the corrections from the BASE that way. In our area we have good cell coverage, but if we travel to the boonies, then we can use the radio AND if we get spotty coverage with the radio I will let the LS cook for a minimum of 30 minutes and we will have a tight solution for that point. We run 2 Javad Base/Rover set ups and we get excellent results out of each. The week link is the end user. We continually train our crews and go through the paces on a regular basis.?ÿ
3. I would take a hard look at the Leica GS18s also. I have a buddy running that set up and he screams its praises. Leica has always had really good hardware. I have never been a fan of the DCs but there is a learning curve with every manufacturer out there with the exception of Carlson. Any surveyor worth his salt can figure out Carlson and be proficient in a matter of hours.?ÿ
Anyway, happy hunting. DM me if you need specifics.
I've gone with the Carlson.?ÿ?ÿ
My thoughts:
(1) Would like to see a quasi-real time PPK solution like Javad.?ÿ Then maybe add a routine to develop a mean/ave soultion for a point? Would also be a great way to do some additional QA/QC. Some say it is coming soon with Carlson.?ÿ?ÿ
(2) Would like to see more info real time about the shot like Javad.?ÿ Surefix/Fixed+ does give me some of that.?ÿ Interesting to hear how some think equipment can either lie to you or tell you the truth.?ÿ My view is it does neither - it just spits data at you.?ÿ The user has to pull out / develop the meaningful results.?ÿ This is just a matter of perspective - no need to argue here!?ÿ I agree with C. Tompkins in the previous post about reviewing the data.
(3) I need a DC that will also run a gun.?ÿ Can't get around this.?ÿ So, sorry Javad (but it does do some really cool stuff!).

Interesting to hear how some think equipment can either lie to you or tell you the truth.
In rtk, "truth" means it is reliable within certain tolerances. Such as + - 0.2'. Or some value.
"Truth" is my foot, is about 12" long. That's truth.?ÿ
Pilate said "what is truth".
Jesus said "I am the way, the TRUTH and the life, no man cometh unto the father but by me". That's truth without any error.
Truth needs a context.
Context for measurements, is it's expected error tolerances. It's pretty essential to all measurements.
When standing on the moon, pointing at earth, and saying "that's where I live" is truth. Even if you are off by several thousand miles.
It's academic.
But, we have digresed into philosophy. Necessary though.
Spring has sprung. Enjoy it.

@nate-the-surveyor I enjoy thinking about such concepts. ?ÿThanks for sharing.

I really DONT Miss running a gun. But, I get it. It would be nice.
I'd like to see Javad and somebody that makes Robots, and/or Total Stations get together. To produce a product of this caliber.
It would be good for construction, I'd think.?ÿ

I guess it depends on how you define "need."?ÿ I *wish* I could unhook the Javad faceplate and processor and run my robot with it, but I can't, so I use a Carlson DC with the gun.?ÿ I don't go back and forth between GNSS and robot much, it's usually one or the other, so this isn't a big deal for me.
@jim-frame. ?ÿYes. ?ÿAnd I run my 1998 Leica robot with a different DC from the DC I use to run my 2014 iGage GPS.
?ÿ
Well, maybe I need Javad. My instruments only provide evidence, not truth.?ÿ
And we both have the same idea as to what TRUTH is.
Well, my Javad provides me some fine evidence, that I can believe.
I am always learning new things. Javad has a routine called "trajectory". It's handy for topo. It's designed for use in open areas. I set mine to record a coord every second. It makes a 3d polyline, with connected nodes. I recently had 1/2 mile of county road to survey. I used a yamaha UTV. Side by side. I stuck the LS on the roof, holding it with my hand, and drove the road 3x. Twice in one direction, and once in the other. When the LS is doing trajectory, it does not have all the good garbage, where it verifies, to provide the high confidence.
But, when in motion, it is stronger in its analysis. It generated 3 sets of data, that were within a foot of each other. Part of this was my failure to perfectly drive the same c/l. This dirt/gravel county road went right under big pines, and through a forest. It also had a few glitches, where it was wrong. A ">"?ÿ shaped glitch, where the 3dpoly jumped about 5' or 10', then went back to the smooth trajectory. It worked astonishingly well, even in the trees.
So, in my language, those glitches sideways, are "lies". So, in this mode, I got it to lie to me. But, they were obvious.?ÿ
Hey, get to work. Quit reading The forum. The leaves are growing fast!

I don't know Nate: that Javad gives me a steampunk vibe, they need to modernize the look; don't you think?
OMG MightyMoe, you may as well have made fun of his momma.?ÿ 🙂
