I was recently investigating a similar setup with trimble gear. It seems that to do that you need a cell plan and cell phones that can do circuit swit...

as Loyal says, OPUS uses 30s. But, you can use anything that is an integer divisor (is that the right word?) of 30: 1, 2, 3, 5, 6, 10, 15, 30. I have ...

David: I do many of these types of surveys, about 30 per year. We use a high accuracy Trimble S6 and sometimes a Zeiss S10 (same accuracy, 1" and 1 mm...

Another oldy but goody GPS boxGavin: TI4100? I never used one, but I do know they were used a lot by military and government.

Al I love trimble productsFor you really old timers:The early Trimble units (4000SL), a firmware update meant they sent you a plastic tube filled with...

I use a Trimble S6, which has a notch at the bottom of the instrument. When you tell the DC you measured to the notch, it does the reduction to the ce...

I was very interested in it, as my BSCE is from there. I began the process a couple of years ago, but it never seemed to gel, so I pretty much gave up...

Shelby-Thanks. That is the conclusion I had reached after some research-that you needed phones capable of circuit switched data connections. All the p...

I don't have a firm number. When I am doing the actual control, I try to keep it under 3 cm. But, this is to compare against the final product, which ...

I subscribe to Keystone, which has a pretty large coverage area but this is outside of that area.

TSC2 base options?If I create a new style, and set base radio to internet connections, then go into the dial profile screen, there are two options und...

Thanks, Gavin. This would have to be very mobile, and would occupy any given point for hours or maybe a full day. When I got my first cell modem (a pc...

a possible solution-not sure if it existsI think one way to do it would be to have software running on a office computer (with a fixed IP that would r...

Derek, that is good to know. I asked my dealer if he knew of anyone who could recell it, and he said no, it was not able to be re-celled.

Consider the value of easily replaced comms connectors -Glenn: thanks for posting that. It now makes sense what they did. I have a hard time sympathiz...

I just bought 2, the first time I had to replace since I bought the dc's in 2006. 5+ years sounds like a really good run to me. Because of the ports, ...

It does, although some (many?) would argue that it is still a single occupation, and therefore not redundant. However, the fact that you have four dif...

Absolutely. You have to make sure the right coordinates and elevations are being held, which takes some getting used to, trial and error to figure out...
