Post pics of difficult shots

I am creating this thread so everyone can post pics of their LS in bad environments getting good shots.

I'll start. 1' from a 10" cedar tree in a cedar thicket. One 240 epoch shot with consistency of 20 and confidence at 25. One 19 epoch shot and one 22 epoch shot. All agree within 0.15.

Today I was collected two shots with a 2 minute duration each, back to back on an iron rod that was on the North side of this pine tree. There was another pine tree 10 feet to my Northeast as well as a cedar tree to my East and various small deciduous trees all around. I did have a few small openings to the sky as can be seen, but not many. The two shots were less than 0.02' apart. Later I will process them through Hybrid RTK and see how DPOS handles this.

Yes, it will be good to see how Hybrid RTK does in tough environments.

As I mentioned earlier, I collected two points on this monument, L015 and L016. I collected for right at 2 minutes (give or take a few seconds). This is the screen that shows the difference between RTK and Base Processed results. If I were relying on the post processed solution I would have recorded more time. That I was able to get fixed solutions at this point impressed me, and I know this receiver pretty well. You'll notice that L015 has a vertical difference between RTK and BP of 0.346 (see row labeled Dist,ft). That's a little wide, but for my purposes the BP solution confirmed the RTK. I haven't run enough tests yet to determine just how independent RTK and BP are. For instance, could RTK and BP come up with the same bad fix? I think it will be very unlikely, but I won't know until I run some tests. For now, what I've seen over the past few days has me really excited about the future of RTK surveying and those of us with Triumph-LS receivers have a front row seat.

Yep. You have to wonder how much interference a bird makes. Certain times of the year I find droppings on the base and think that bird had to be sitting there for a while.

This is impressive. So that I fully understand, is the static file used for the DPOS processing recorded at the same time the RTK shots are being done? Matt, apologies on veering away from your original post!

Boy, I can sure relate. The backpack, and the Schonstedt, and (I'd guess) the backpack, with 100' tape, sandwich, can of kippered herring, flagging, marker, and a few other goodies! O! Yeah!

It seems that there are a number of developing philosophies regarding the settings in the LS. Would those of you who post to this thread, mind SHARING your favorite settings, for working in these environments?
At one time, Mr Javad offered a 10k reward, if you could get an LS to lie (bad fix). Many folks stepped forward, and said NO! Somebody out there, will figure out how to collect that money.... or will learn some goofy stunt, such as aluminum foil, on the top, to fool it. (put your favorite scam there)
Anyway, AFTER this, "Beast Mode" came out. And, all the different methods hit the ground. AS I listen to every user who will share, there are a NUMBER of ways to use the LS.
And, the available methods are also changing. ie, TIME and EPOCH are now separated. You can stop by time, (2 minutes) and 60 epochs. So many options. And, I still have clients, to work with, and deeds, and just want to learn different things, and methods. I can see some settings are better for some environments.

Thanks for all your sharing. Tell us your settings, and what you learned, etc. And, we will all learn more. Further my education, and I'll try to further yours too!

Nate here are a few screenshots with the settings I was using for the points in the pics above.

Thanks Adam. I've never set it up to a confidence of 25, and a Consistency of 60. I have done multiple observations, though, in the tight spots. I'll try that.

Here are a few pics of the job I am currently working. With beast mode I was able to run out 6.75 miles of boundary and 5.7 miles of control in a third to half the estimated time. Out of those miles I only had to run line for 400 ft of it and in that 400 ft I checked into some LS points and a couple of hundredths was the difference! With beast mode I use 600 epochs, 2 engines for V6 and 1 for validation with 10 for confidence and 20 for consistency. I was able to get a bad solution only because it was getting dark with briars to fight for walk out so I stopped it without validation completing. Validation or repetition or both are vital in multipath especially with beast mode, I personally do both. Anyway loving the system and a big thank you to Javad and all the folks involved in the design, development, and of course testing by fellow surveyors!

Awesome pics Monte! What part of the country are you in. My pics are from North Carolina.

I am from Minnesota but these pics are in Massachusetts just outside of Boston. My office covers 31 states east and bordering the Mississippi river.

Adam, thanks for posting that. Maybe you could share that over on the "Survey Connect" forum. I have been wanting to do that for a while, but you did it for me! (ha!) My feeling is that MANY surveyors who work in the open, and nearly all open areas, don't care about this. BUT... for those of us who do work in the woods... it's the bomb!
