How to setup a new base point using Trimble TSC3 and Rover R8

Hey guys,Just wondering how one would go about setting up a new base control point for use in a mine surveying scenario using a Trimble dGPS.A previous surveyor who used to work here knew how to do it, but I do not. He mentioned something about setting up the equipment and then running static observations for several days? That's about the extent of my knowledge as it stands.So I'm after any advice in doing this, or if someone could point me to a how to article or online guide that would be…See More

"Jose is correct. We are talking within a half inch of accuracy basically. Repeating and averaging over multiple days will also help."

"You'll have basically the same degree of accuracy you had before, I think. In order to establish a very good quality you´d need a static survey tied to at least 2 more points with known coordinates. Normally I prefer 3 points to enclose…"

"Ok things are starting to make sense now. So what degree of accuracy would we be looking at if we were to do RTK? Because while we may not need a high degree of accuracy at the moment, this point will be a permanent base point and so someone may…"

"The static achieves basically an Opus solution on a single point. Static is more for making entire networks of control where you have 3 or more units occupying points. RTK (which is what you're doing by using a base/rover) is just as accurate…"

"Ok thanks for the help William that sounds pretty straight forward. On a side note, will the static obs method not work? Or is that not really what static obs is designed to achieve?"

"Ok. So to basically be on the same coordinate system as that peg, you'll need to do a single point transformation, or what most contractors would call a localization. Basically, set your base up in the new point and just hit the…"

"Well there is an existing base point nearby that we have been using for survey work, but it is simply a metal peg in the ground that we have to set a tripod over every time we want to use it. So we installed a steel post into the ground with…"

William Kenter replied to Zac Large's discussion How to setup a new base point using Trimble TSC3 and Rover R8
"The answer to that varies based upon what you are trying to do. Is it supposed to tie into an existing control network or are you starting completely fresh? If you are using an R8 and setting a fresh point, I'd collect a half a day of data or…"
