Base with Trimble 5700/5800

Probably a dumb question - but I'm using an old dinosaur GPS setup for some of my work here: original Zephyr antenna, 5700 receiver, Trimark III for the base and a 5800 rover.Question is:  If I…Read more →

I had a fun and interesting practice job last week - setting offset staking for grubbing and rough grading of 700' of driveway heading down steep, rocky, wet jungle.Fun part was using a Trimble…Read more →

GPS vertical results varying too much

I've got an old Trimble GPS setup - a classic Zephyr Geodetic, Trimark III, 5700 base with a 5800 rover.  I'm pretty much just using it for grading and building/utility location as we slowly build…Read more →

I've been using Trimble Survey Controller 12.5 on a TSC2 with an old Zephyr/5700/5800/Trimark III setup and started setting that DC up to use with my Leica TCA1101+ total station today.  I have a new…Read more →

Base with Trimble 5700/5800

Probably a dumb question - but I'm using an old dinosaur GPS setup for some of my work here: original Zephyr antenna, 5700 receiver, Trimark III for the base and a 5800 rover.Question is:  If I swapped out my base setup with something that would pickup other GNSS systems (GLONASS, Galileo, etc) like an R8 model 3 or even a Zephyr Model 2 antenna, would I be able to receive info from those other systems even though I'm still using the 5800 rover?TIA,DaveSee More

"Not upgrade your base if you are on a vrs just the rover.  A virtual network acts as the base, so you do not need to set one on site.  So you use your GNSS enabled receiver as a rover and it collects with Glonass and even better BeiDou…"

Dave Drahn replied to Mohammad Salem's discussion Civil 3D 2017 do not show up the real surface as it's on the site!
"You might also start by making sure your wall lines are breaklines that are included in your surface, providing an offset (not quite vertical) "base of wall" and adding elevation points (not PIs) to the breaklines - you can add them in…"

"A stand alone base setup like you are talking about both base and rover need to be able to pick up GNSS. You also could also use the same rover on a VRS network. Only if the VRS moint point is GNSS capable will you benefit."

Kevin D. Allen replied to Dave Drahn's discussion Base with Trimble 5700/5800
"Quick answer.... no...            long answer,yes   you still get the proper corrections for the base as it handles the GPS signals, you will not benefit from the additional GLONASS of Galileo signals as your…"

"I think that reply answers my question.  Thank you. If I'm understanding you, I could up grade the base and collect other GNSS if I were hooked up to a VRS?  Otherwise, no?"

Aaron Baxter replied to Dave Drahn's discussion Base with Trimble 5700/5800
"If you have a R8 model 3 on the base it will broadcast the GNSS to your rover. Your rover will also need to have GNSS capable another R8 model 3. I use the same setup and it works great. Just needed to set the base setting to use the R8 and check…"

"Yes, our company has used the same setup before. We have a spare 5700 receiver and a Zephyr antenna and have used them when we've sent out our equipment for repair. The main thing is to have all of the settings exactly the same in the base…"

Matthew Jennings replied to Dave Drahn's discussion Base with Trimble 5700/5800
"Would you be able to receive GNSS as well as GPS? Yes. Would it help you at all, no. If one receiver is picking up 3000 seats and the other is only picking up 7, it only uses the 7 that are in common. If you want GNSS, upgrade one, and be aware…"

"I joined a crew not too long ago that was upgrading to the R8's but retained a 5800 from the old settup to use if needed.  There were a few settings to change in the survey styles of the Trimble Business Center data collector. It finally…"
