Javad LS or Triumph 1M?

I have used the Triumph LS-Triumph 2 for 6 months now and am very impressed with it;-) . Fast fixes with confidence in the data collected. The whole unit being combined makes for convenient handling. I've got got some large topo's coming up, so I've got my helper/handyman fabricating a "door with mount" for our UTV it so that he can drive while I collect data:-) .

Cool, thanks for the info. I have never used any of there projects and I am on the East coast. I have used other gnss equipment. It seems javad's approach to running multiple engines will at the least provide a little more ease of mind when leaving the site.

I've enjoyed using the Triumph-LS. I think the form factor is odd to most people at first, until they use it for a few days. Negotiating through brush, or packing it up in the survey chariot to head down the road to the next point is far simpler than with the current layout for most RTK receivers (head on a two meter pole with a data collector and bracket midway down). I use a thumb drive to move collected RTK points from the LS (in ASCII format) to my Carlson data collector for terrestrial observations (total station). Works great.

I think the LS is by far the most advanced integrated receiver on the market. You have to either get used to the all-in one design though, and it is not for everybody.

On your options: You have to remember the Triumph-2 is s slightly different spec. #1, you will not believe the size of this thing, it is amazing when you hold on in your hand the first time. A very very capable receiver for its size. It is super cool when you just turn it on and it automatically connects to the RTK radio via bluetooth. You have to remember though that this receiver is GPS/GLONASS only, it does not get the additional constelations, if that is important to you. So if you use a pair of these for RTK, or use this as a base for teh LS, then you "only" get GPS C/A, P1, P2, L2C (L+M) GLONASS C/A, L2C, P1, P2 SBAS L1.

If you go with the Triumph 1M for a base, then the signels will match with the LS: GPS C/A, P1, P2, L2C (L+M), L5 (I+Q) Galileo E1 (B+C), E5A (I+Q), E5B (I+Q), AltBoc GLONASS C/A, L2C, P1, P2, L3 (I+Q)
QZSS C/A, L1C(I+Q), L2C (L+M), L5 (I+Q), SAIF Beidou B1, B2 SBAS L1, L5

That is IF you were to activate them all. If you are running on a network, then you are likely limited to GPS, and maybe GLONASS. I don't think any US systems are providing additional corrections as of yet.

So, a pair of Triumph 1Ms and, a Triumph 1M + an LS should give you the same capabilities, provided that the new data collectors will perform all of the internal magic that the LS will. You will need to see if all of the features you are interested in will be available on the particular DC.

I think my big question, and I am going to check this out soon, is will a pair of Triumph 1Ms, mate up well with a Carlson Surveyor2, well, and will any of the additional Javad features be available - beyond just basic RTK corrections.

If you get one, post up some pics and a review, not many people share info about the green stuff.

I have a pair of Triumph 2's, unfortunately the Victor LS Data collector to run the rover "has been not yet released" since Dec. so I'm "Stuck":-D with an Triumph LS:love:.

Why would you use a Triumph 1M over a Triumph 1 base?

TRIUMPH-1M supports Beidou, TRIUMPH-1 does not. Today, it doesn't matter much as there aren't enough Beidou satellites to make much difference over the continental US. Also, TRIUMPH-1M uses the newer boards with less power consumption and have more battery capacity which will equate to longer run time between recharging.

Shawn or any other Triumph LS users. I have been using the 25 mm adapter provided by Javad, but I'd like to use this doohickey with a regular adjustable rod. Anyone using this? If so, would you share which model # rod you are using? http://www.surveying.com/Products/Prisms-and-Assemblies/Other-Prisms-and-Accessories/2131-02

For some applications, I'll put the LS on the 25mm adapter and attach that to a standard prism pole with a bipod.

With the doohickey you linked to, I notice it's a 5/8x11 male thread instead of female. Might be a trick finding a pole with a female thread.

I don't see any benefit to using that adapter, but there are couplers available to adapt the 5/8" male of the adapter to the 5/8" male of a standard pole. If you don't mind the weight, you can get one in galvanized steel at your local hardware store; just ask for a rod coupling nut.

I use the Javad adapter on a quick-release and use the LS on the same rod I use with a Leica mini-prism. The quick-release is especially handy when I'm driving from point to point, as I can lay the pole in the back of the truck and set the LS behind the seat.

Here are some photos of an old rod. I think the SECO adapter would work. My problem is all of my rods work with Trimble MT1000 prisms, so the graduations on the rods don't read true when using any GPS. I normally use a 2 meter fixed rod for GPS work, but the LS is a pain to use at 6.025 meters, so I prefer to use a standard and measure it with a pocket tape, but then the graduations are jacked up. I am smart enough to work around the issue, but I have 5 other employees and I am trying to cut out some possible errors down the road.

If you determine a constant for the true HI minus graduation HI you could use the vertical offset in instrument height on the LS and just enter the graduated height.

Hardware wise I think you're on the right track.
