GNSS Performance Under Heavy Foliage: Trimble vs. Leica

Another thing is the eBubble. With my very limited knowledge on the R10, I am not sure if the eBubble provides some form of correction if tilt is within tolerance.

Kind of reminds me of a scene from the movie Haywire starring Gina Carano that I watched recently on HBO.

In it she has a smartphone that tracks someone moving inside of a building. She was also inside of the building. She was able to track the red dot moving from room to room.

Must be a Leica phone.:bye:

People have been claiming that for years. I will be surprised if this claim is true. The facility is supposedly going to be commonly available when the new block of GPS satellites are aloft with the additional frequency.

Some of the current fancy claims don't point out that it takes 30 minutes to initialize ...

Until then I'd take it with a grain of salt.

it is not possible to initialize without taking time.
HD standts for High Defininiton TV video or something, this is marketing shi...t

Never uses Leca GNSS.. only TS, and thing I learned is their user user interface and manuals suck.

If you choose between two evils, trimble is better evil.
not in a good mood today. :-/

I think you should weight the software as much as the hardware in your decision.

I sell Leica...which may make me a bit one-sided, however, I am not one to drink the kool-aid. If there is a better product on the market, I want my customers to go that direction and I do what I can to help them.

That being said, I am not one to buy into gimmicks. If I was a Surveyor, my sole goal would be to provide the most accurate and repeatable data available. I don't care if it "may" fix under the trees or "may" work for five mins after your hotspot goes down. No, I want a unit that will provide me dependable results in the environments that the GPS/other Equipment was made for. GPS is not made for the woods, and though it's really cool, and sometimes really helpful for certain jobs, that is not what it is for.

Now if the Trimble R10 is trying to push that envelope and say that is the optimum environment, then I would be dead wrong. I don't think that is what they are doing though.

I like the Trimble R8, I like the Spectra Epoch 50, the Promark 800, the Sokkia GRX's and the Leica GS14's. Why? They are all reliable, they are all "repairable" and they cost a lot less than the high-end machines that are really overkill anyway.

Again, most important is to have a dependable local dealer that can support and repair the GPS. Equally as important is the software. Proprietary software or third party software? I tend to lean towards Survey Pro or Carlson SurvCE. It runs more than anything else on the market, runs it well, both have a loyal following (making it easy to get on Beerleg and ask questions) and both spend a large amount of time trying to improve their products.

Good luck with your search.

Let us know if you test it. My experience is similar to what others are saying. GPS is not good under trees. I just setup my control outside the area and traverse in.

> With all these new technologies from Trimble, does the R10 provides better power/solution under heavy foliage than with Leica GS15/GS14?
I haven't had an R10 in my hands. I have used the GS15 and have been very impressed with how much tree cover it can tolerate. But I think it probable that Oklahoma underbrush is a whole different animal from Philippine jungle.

The Leica and Trimble salesman each have powerful propaganda. Each salesman honestly believes his is true and the other guys is a lie. That is how they are able to make their claims with a straight face.

Both manufacturers have "xfill" that allow you to keep getting positions at a heavy cost in accuracy.

Get both of the units out in the real world conditions for a test before buying.
