J-Mate

Wow, just finished watching the video about J-Mate... very interesting and seems pretty cool. Maybe it's too early to start asking questions but here I go. The angular encoders, what the specs of these? What kind of angular precision and accuracy can we expect with this? The Javad Team definitely thinks outside of the box, that's for sure.

To anyone with a robotic total station and/or a terrestrial scanner, the J-Mate might seem to be a solution in search of a problem. However, if you don't have a robotic TS, it could be pretty useful (depending on the price point, of course).

We are entering a new realm in surveying. I don't think the distance limitation will hinder me much. Of course I don't work in wide open spaces for the most part.

Ever since I first tested the LS, I have suggested and advocated for the integration of a laser measuring device with the LS. The J-Mate appears to truly tackle this and then some.

Very exciting!!
In my mind there are some major points to be considered:
Price point;
Software/hardware interface;
adjustment of collected points with DPOS of project.

Everything else is just tweaking of the system.

Looks like it might be here for Christmas! How do we get on the pre-order list?

Just completed watching the video. This is an awesome addition to the Javad family. And clearly, the dimensions of the current LS are intended to remain unchanged in order to couple with the J-Mate. The "Astro" function is really quite amazing. Takes me back to sun shots with old Wild T-2s. And the 100 meter+ limitation will not be a problem for 95% of surveys, particularly coupled with the LS GNSS functions. Very, very innovative. I simply love to see Javad thinking out of the box. :cool:

This is an all reflectorless setup then - no prism needed? Once it's set up and backsighted, it basically operates like any other robotic total station, with the plus target and LS on the other end?

This is something I would consider. I don't have a robotic TS, and don't need one often enough to justify the price of other robotics, but for this price I could see it. It would be perfect for when I have to detail encroachments of building, fences, etc., where the GNSS is kind of a hassle.

Very exciting! I didn't know this was on the horizon and have lately been thinking of ways to accurately strap a laser to my rover rod!

Amazing innovation and well worth the asking price. Now if I can only find a buyer for my robotic package before the November pre-order deadline:) I've shared the link around and anxious to get some feedback from those in my neck of the woods.

I would love to get my hands on one of these!

I see many uses for this equipment that would be very beneficial, and productive for the varied types of work I have been, and am still involved with.

I was truly, and pleasantly surprised with the inclusion of the Astro Azimuth determination function.
Being an old school Seismic Surveyor (Doodlebugger) I have literally taken thousands of sunshots for azimuth determination and rectification.
Some of the traverses I have run were over two hundred miles in length, not much in the way of accessible control along the way, and even in the good old days, helicopter time was expensive.
Knowledgeable clients would allow, or even encourage us to run leapfrog solar traverses, half the setups, twice as many points from each setup.
The motto for most surveyors who worked out west was "Shoot Far, Shoot Fast, Shoot the Sun Whenever you can."

Given the price point for the J-Mate, as well as a Triumph LS, along with a base station, and radio of your choice, it would be a very foolish decision to overlook Javad if you were starting from scratch. I do not think you could get a new, full blown RTK GNSS system, along with a robotic, or reflectorless (passive distance measuring) total station from another manufacturer for anywhere near the numbers I have come up with in my head.

I've been thinking for years of starting my own business, but the cost of the equipment is a substantial startup cost. The Triumph LS and a T2 or T1M base solves part of that, and now the J-Mate answers the robotic total station part. Now I have no excuses I guess! If only the Triumph drone was ready for market, I'd be all set...

As stated before, I am very curious about this new product. From a price point, I think that if you already have an LS and don't have a robot, this may be the way to go, especially at the introductory price point. I guess it depends just how much you want the "total integration". On the other hand, robotic total stations have come down in price. I can buy a SP Focus 35 for $16200 and have a very nice robot. Another $5850 will get you a Ranger 3 w/ radio and Survey Pro on it. Total of $22050. So for $2000 more than the standard price of the J-Mate, one can have a good proven robotic setup with no distance range limitations. Everyone will have to weigh out the options for themselves.

I am curious how long it takes J-Mate to do a solar shot and how repeatable the azimuths derived from solar shots are. I will confess that being a younger Surveyor, the only time I ever did a solar shot was in college:eek::eek:. To me, what is slow about a one man crew using a robot is traversing. All the back and forth. If the solar shots produced repeatable azimuths, then maybe backsights could be eliminated with J-Mate, which would be a big advantage over robotic total stations. Thoughts? Has there been any real life testing of the J-Mate yet?

I am assuming the L.S. and target act like a prism so the JMATE can collect points like a normal robot if required?
