Regarding that chapter, you should use as your network topology, the
example 4 (Wifi) or 5 (mobile phone network), and replace on both of
those examples the block "RTKNAVI" by Spider (and maybe move Spider
to the "Base Station" or reference receiver's PC, and "STRSVR" to
the remote receiver's PC) . If there is going to be line of sight
between both locations, a Wireless Router or Access Point connected
at the Base Station's PC Ethernet port (or wirelessly), an a USB
wireless adapter with detachable antenna at the rover's PC (this
one, for example: <a
href="http://www.tp-link.com/en/products/details/?model=TL-WN722N">http://www.tp-link.com/en/products/details/?model=TL-WN722N</a>),
with both antennas (the AP/router and the USB adapter) replaced by a
directional Wifi antenna like this one: <a
href="http://www.tiendecita.com/antena-wifi-planar-estanca-marca-abaks-p-99.html">http://www.tiendecita.com/antena-wifi-planar-estanca-marca-abaks-p-99.html</a>,
should do it. (Note that the antenna does not include the coaxial
cable needed to connect the antenna to the AP/router (that by the
way has to have a detachable antenna also, in order to replace it),
but that cable can be easily found on computer stores). The USB
wireless adapter used at the remote receiver's PC should be placed
inside the box behind the antenna, were the RP-SMA connector is. <br>

</div>
<div>Well... At that point I have to disagree with you. The
options (and there are many options) are listed and very
briefly described. Almost never exemplified and never
explained. You must have a strong background on GNSS
positioning techniques to fully understand most of the options
at user diposition.</div>
</div>
</blockquote>
<br>
My fault, no examples...but at least RTKLIB has a manual....and
there are screen captures on it!! At the GNSS positioning techniques
FOSS world, those features are not very usual... ;-). Based on that
brief descriptions, you would be able to find better explanations
somewhere else: papers, doctorate theses, GNSS equipment
manufacturers, etc.<br>

<br>
You will be sensing large structures, right? In that case, I would
go with "static" (static rover, static reference), not "moving-base"
(moving rover, moving reference) nor "fixed" (constant distance
between rover and base). Maybe you could go with kinematic too, if
the real-time displacements and deflections of the structures
studied can be considered as "movement".<br>

<br>
I think I never fully understood this option, I can't give you a
better explanation than that stated on the manual, so if anyone has
a better understanding of it please enlighten us. <br>
