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" target="_blank">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" target="_blank">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></blockquote><div><br></div><div>Once again very useful tips. Thanks.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

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... ;-). </div></blockquote><div><br></div><div>Yes. I must agree with you. The manual is very good.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">
<div bgcolor="#ffffff" text="#000000">Based on that
brief descriptions, you would be able to find better explanations
somewhere else: papers, doctorate theses, GNSS equipment
manufacturers, etc.<br></div></blockquote><div><br></div><div>That's what I'm trying to do these days... </div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

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></div></blockquote><div><br></div><div>My structures move at relatively high frequencies (say from 0,1 to 5 Hz). Most of the movements are small (a few centimeters at most).</div><div><br></div><div>Best regards</div>
