I think I need a new base battery (RTKGPS)

Real Time Networks don't rely on batteries. Zero baseline lengths also provide zero ppm corrections. Got a cell phone with a data plan? Frees up your base to act as a second rover ... 100% increase in productivity.

We are in Jeff Foxworthy's inlaws cousins woods. Ain no such thang roun hear!

> Zero baseline lengths also provide zero ppm corrections.

I've often wondered about the "zero ppm" claim for RTNs. I get the part about no slop in the vector from base to rover, but I'm thinking that the "virtual base" must be modeled, and there must be slop in the model. How does it work out in the real world?

We have base/rover set ups and RTN rovers (Trimble VRS, R8 receiver).
It has been my experience that the base/rover set-up yields more accurate results, and obtains a fix quicker in tough environments.
We often work in the boonies w/poor cell service...so that could be a concern too.
Obviously, no cell service = No VRS.

As far as batteries go for the external 35 watt radio, I had good luck with Interstate. It's out in the truck, but I'm pretty sure the model is DCM0035. Last time I bought one, they gave me a knock off Chinese version...

Optima Blue Top Deep Cycle.

They're pricey but we have two of them and one is going on nearly 5 years. Yes, 5 years. They have a built in handle. The kicker to managing the life of them is to always charge at a 2Ah charge and always run them down as far as you can each day.

I have an odyssey dry cell. It has worked well. But, it is heavy.

What capacity is sold with a standard setup these days?

Isn't it a SLA (Sealed Lead Acid) battery)?

I thought of gettting one of them, and going up about 20%.

OVER buying a base battery seems to not make the battery last as long.

Thanks,

Nate

Nate-

I must be a bit thick so bear with me ...............

Are you saying when on a remote site your "base" battery has both the electric fencer and the GPS attached ?

Cheers

Walmart. Everstart 24DC-6 Marine for Trolling, Deep Cycle, RV Get a Nautillus Gold 12V Fully Automatic Deep Cyle Charger. Save the sales slip as they are under a good warranty. Also you do not have to cycle the battery down before recharging again. They do not have the memory retention like the Nicads.

I run everything off either sealed lead acid or gel cell batteries. A wholesale place has them in all sizes. For GPS receivers I have some 5Ah for packing up to 12Ah for long static sessions. I run a Geodimeter 620 total station with same. For the RTK base receiver and 35 watt radio I have a car sized gel cell. Nice for jumping dead vehicles also. I made all my own power cords. The whole setup of about 6 batteries cost less than one pretty manufactures unit of say 12Ah.

Yes, Derek, Have you ever heard of COWS? (Not "our" Holy Cow, mind youk, but those kind that knokc over base setups?

This is what I used for a fence, worked great.

I also used the Optima yellow top for my 35 watt radio, but would suggest the blue top.

Livestock will disturb survey setups. Horses are the worst. Set something up in a horse pasture and it won't last 10 minutes. Most exciting thing for them all day!

Do not setup near horses

A few of my control points have been corrupted by the presence of horses in adjoining pastures. I normally set control points 5-10 feet from any R/W fence.

When I set them, they were in great locations. A few have put upgraded fence next to my monuments and moved it closer and within reach of their beasts.

Last incident destroyed a tribrac. Snapped it off tripod, bent/broke many components of the locking mechanism. I am glad it was on the other side of the fence from the horse, my whole PM3 setup could have been destroyed.

Dang Nate,
I think a Big Help with a willow switch at the base station would be better than an electric fence...

I figure a camp chair and Skelton's Boundaries and Adjacent Properties would do the boy some good...maybe he could teach us a thing or two...(and maybe we could claim PDH's)

I have a Zareba Yellow Jacket.

It can run on it's own batts, or hooked to 12v.

I usually run it on "Training" mode, in case somebody needs to "know" what the lectric fence means!:-P
