Does the trimble data collector have a mechanism, to:
Start an observation.
And it automaticly stores the shot, when certian perimeters are met, and starts another observation. Endlessly, until stopped.The Javad does this. Set it up, go to lunch, come back, and an hr later, it has 8-10 shots.
It can run like this for 12 hrs. Or, 24 hrs.
Then, you can average that pile of coords.

Well it’s not leica! They don’t give much away
From Leica “Simply put, RTKplus is like RTK but better. RTKplus intelligently adapts to changing conditions by selecting the optimal signals to deliver the most accurate positions. Work more efficiently and in more challenging environments than you??ve ever worked in before”
Meaningless drivel. Especially when you compare it with the published science of Trimble’s HD-GNSS. I imagine that Javad also documents how they achieve the reliability and redundancy that we crave.
And how would you guarantee 99.9% reliability anyway? You’re throwing away any credibility in the first sentence.
I think its also customary to let other forum users know (in your signature) if you are a dealer.

GivesYes. You can set the collector to store the shot when your perimeters are reached. I assume you can have it continue to observe again? Never tried. There is a continuous observation….I’ll give it a try and see if I can set it to average. The average setting in Trimble Access is also weighted, meaning that the highest quality shot is given more weight than a poor one..

I think “continuous topo” will only allow instantaneous measurements unfortunately. Good way to get lots of shots and see the variation though.
I have a different technique I use when the receiver can sit on a point for a long period… it’s called “static”.
If I care about a point enough to observe it more than once with RTK then I’m going to measure it as an Observed Control Point, allow as much time to pass as is practical, then re-measure it as an Observed Control Point with the pole oriented 180 degrees opposite the first shot.
Ideally enough time has passed to where I’m seeing a completely different constellation, but this takes 3 – 4 hours and so isn’t always practical. With the R10 you can reset the satellite tracking, which at least guarantees a complete loss of lock and a somewhat independent solution. I say “somewhat” because without the passage of time you’re still looking at more or less the same constellation.
Hey, Lee, I turn static on for most shots. So, I get both. At the same time.
Static, and RTK.
Static is at 1″ intervals.
And, I use it for beyond radio range shots.
NAre you processing the static against your RTK base or using Javad’s PP service?

I generally process against my base (when I use one) and CORS, as that lets me determine the reference position.

Maybe one of you smart guys can create a survey style sheet where the receiver will log a 180 epoch observed control point, reset RTK Fix, log another point for 180 epoch and average the points, for a set period of repetitions or time?

OK, Yes, and Yes. And, Yes some more…
When you Post Process, with a Javad, you either hook to the internet with wifi, or a LAN Wire. (there’s other ways, but that’s all I am used to).
Then, there are CHECK BOXES.
I usually check off so that:
The base processes off cors. This gives you a SHIFT from autonamous to SPC. It also has a check box, to update all the shots or not. MOST of these shifts are about 2 feet horizontally. And, less than 6 ft vertically.Then a check box to Process all sideshots off the base. this gives you BASE to ROVER processing.
Then, another check box, to process all the ROVER shots off CORS.You could go to job, forget a shot, remember it and return to job, and ONLY set the rover up, and perform a CORS to ROVER on it, and IF your cors are not too far away, get a GOOD SPC shot, in 15 minutes.
My CORS are too far away.
ALSO, you can set the LS to run autonomously . MOST shots are within 3′.
In fact… you can do this, with WAAS. Survey a river, without a base. But, now I sound like a salesman, and I’m not. It’s just a good system.N

I don’t know of a way to do that, I’m afraid.
But I also question the real world value of it.

Hemisphere / Carlson (S321 / BRx6) claim the reliability of solution when “Fixed +” status is reached by using dual independent processors and comparing the solutions realtime.
Have I designed a robust experiment to test this? No…
If your work is always in a wide open setting, this fancy multipath mitigation technology is less relevant. It definilty give the marketing department material to work with.
[USER=7070]@StLSurveyor[/USER]… Looks like Saturday will be available… Meet @ a nice pine thicket, and find out… Are you coming?

I just sent you a message. I will not be able to make it. I have too many things going on with the kiddos. I am all for another time. I just didn’t see the announcement early enough. I will be at the short courses this fall and I will bring it along then. I will also be going back home to Kentucky here in the next week or two, maybe I can meet up with Matt?
Yes feel free to call me when you have time. I’ll make it happen.

Lee,
I know you have posted it before but can’t find it. Can you explain how you reset the sattelite tracking? Feel free to shoot me a pmThanks

We are running Carlson and really like it. Anyone like their GPS hardware (I think I’m looking at a Brx6?!).
I think the best is the GS18 T from leica
We got two new R10’s about 3 months ago. Both are VRS capable, they also have built in low power radios and we got a 35 watt high power radio also. Very powerfull system since we can use base rover or jut use VRS, but like someone said above, very expensive, about $46,000 dollars including tax.
