Real-time DGPS Accuracy
The accuracy of differential
GPS not only means that your
databases have better data, it
also makes locating previously
mapped assets in the field
quicker and more accurate
too. With differential GPS,
distinguishing between closely
spaced assets is fast and unambiguous.
Back in the office you'll
save time too. Since the data you
collected was corrected as you
gathered it, you can transfer that
data directly into your GIS
without the delay of a separate
postprocessing step.
Cable-Free Convenience
To complement the convenience
of Trimble's handheld
GeoExplorer® 3 system, the
BoB differential receiver communicates
with that system
automatically—with no cabling
or accessories whatsoever. There's
nothing to connect, nothing to
forget, and nothing to carry on
your back. Your crews will move
faster and incur less downtime
due to snagged or broken cables.
Rugged and Easy to Operate
No matter where your data
collection and update projects
take you, the BoB receiver is
ready to follow. Shockproof and
water-resistant, it will withstand
all the rigors of fieldwork, in any
weather. Right out of the box
the BoB receiver is ready to start
working with your Trimble
GPS/GIS data collection system.
Within seconds of powering on,
it automatically selects the best
beacon and starts transmitting
corrections. If you want to
reconfigure the receiver in the
field an easy-to-use two-button
interface simplifies the process.
Powerful Software
For more extensive configurations
the versatile PC-BoB
office software makes it easy to
exclude beacon stations, define
custom display names for stations,
and configure the initial
tracking mode. All in all, the
BoB receiver is the most convenient
and versatile beacon
receiver we've ever developed.
* Some countries may not allow transmission on
the frequency the BoB receiver uses. BoB
reveivers sold outside the US have the cablefree
option disabled and must be used with a
cable.
