I really like the S6, we use it a lot for high accuracy work, as well as for other day-to-day work like topo, etc. That said, if starting over I might...

3 mm between them is very doable with the proper instrument. we use a Trimble S6 high accuracy model for deformation surveys, and our goal is 3 mm ove...

Back when I was using a T2 for daily traversing, I was working on a steep mountainside in West Virginia. I always put the gun back in the bullet case ...

For a traverse I always do D+R, that eliminates the vertical angle error. Topo shots (D only) would of course be affected. I don't think the presence ...

hey RoadhandI have been to a few out-of-the way places while working along the various borders. We surveyed all the crossings (and did photo control i...

New Orleans in 93. I remember because my wife was 9 months pregnant. The doctor said another week or two, so I went to ACSM. My daughter was born on 0...

Not to give anyone any ideas, but...the RTK base transmits its position as part of the data stream. A sophisticated criminal could use a radio and a P...

A long time ago we put "DANGER-RADIOACTIVE" tape around a base. Of course, that doesn't deter the illiterates. Or maybe "HIGH VOLTAGE" might work...

hmmmm...that's a thought. Except I lost it in Tennessee. Very foggy in the AM when I set it up, then when I came back i could see that was a dumb plac...

A person who steals a man's tools that he uses to make a living should be executed! Or at least whipped.When I lost a base years ago it was a terrible...

Right now I am worried about the baseball team...lost 7 in a row but won last night. As for the Steelers...They arrested two running backs this week f...

No, I would not call it a sales pitch. Of course, the exhibits are Trimble (and suppliers of non-competing stuff). Definitely a great place to learn a...

the Great Arc is a fascinating read.when I worked in India (early 90's), we recovered some triangulation stations to use for control. But, the actual ...

Not to be missed, Jim! It has always been worth sticking around for the gala dinner. The last few times I took the red-eye back east after the dinner,...

It has been an ongoing issue with getting updates, going back about 10 years or so, I am always willing to pay to be on software, firmware, and hardwa...

I downloaded the latest ngs_antennas.atx, which does contain the CHC X90D-OPUS antenna. However, when I run TBC (2.81), I do not get that antenna in t...

If I include OPUS or OPUS-RS results in an adjustment, I do it by including the vectors rather than the positions.
