redundant locations are taken on each important point.Redundancy is your friend. If you have several observations on a point and they are not in a fa...

I'm pretty sure where this would go if in Utah. California maybe not from a few cases I've read and other things I've heard through the years.

In 2002 I worked as a sub consultant on the Salt Lake City I-15 rebuild before the Olympics. I was basically working TerraModel for a field office do...

Baaaad RTK or Not? - Check ideasI still use the 4700 as a RTK rover. I ditched the Trimble backpack and also the big radio antenna. I've bought hiki...

Baaaad RTK or Not? - Check ideasIf I got a hold of one of the new GNSS units, probably wouldn't believe it! Whether I'd want to dedicate a half year'...

I've done this many times. Setting up for a static observation but have an RTK base going. So I'd do a 3-5 minute RTK before starting the static. W...

For What Purpose?From my view TGO was better than TBC in some ways. In TBC they took out some really good stuff like formatting custom reports. If y...

On more important points (like section corners) I always reinitialize. For this little sub I did it for every set corner. Get a fix, make an observa...

For What Purpose?I haven't used all software. I use TBC. In a points report you can set it to show the scale factors. So for a small scale LDP (say...

I doubt Kent would use a GNSS RTK if you gave it to him free! For the rest of us RTK seems to work pretty good.My equipment has about reached (or pas...

I don't have total confidence in any measurement system until I've done some redundant checking. There are certain conditions where I've experienced ...

I've had bad fixes before but these usually bust 5 feet or so. In pine trees you can get say a half foot difference with observations taken one right...

I've done enough RTK over the last 15 years to know you can get bad numbers. Of course what is bad and how far is bad is a relative term (to some of ...

Dunno Kent, not much in Wattles like the metes and bounds you produce.Basically the book is fine, but with word processors and all that there is so mu...

Maybe I should sell mine. The book is very dated.

I almost never work an area with enough vertical BM's to do the 3 or more point calibration (lucky to have one good BM). I've never done one. The Ge...

I haven't used a calibration since about 2000. Never liked the idea from day one.I get control points using OPUS (at one time CORS). So then I'm on ...
