Let's not overlook the fact that it is only half duplex, which results in
more collisions on the uplink, uncertainty over whether you were heard, and
generally more chaos. Full duplex operation always tends to be a better
experience for everyone on the pass, and is the more refined method to
operate.

Date: Tuesday, May 19, 2009, 12:07 AM
I am trying to install the FTDI driver (as per the LVB Tracker installation
instructions). I am downloading the VCP software successfully. (Win XP, 2.93
Ghz processor, 1.5 Gn RAM)
I click on the CDM release info Word Document, and the Windows Installer
box pops up "preparing to install". I then get a Word error message "the
command cannot be performed because a dialogue box is open.Click ok, then
close open dialogue boxes to to continue". But no dialogue boxes are open!
If I move the cursor to the Wiindows Installer box's "cancel", the cursor
changes to an hourglass. If I click "ok" in the Word Error box, all the
windows close and I am taken back to the folder where the unzipped FTDI
download files reside.? Any ideas?
Thanks

One important feature of circular to circular antenna reception is the 30 dB
of rejection of signals that are opposite polarity from ground and building
reflections that will cause QSB on linear antennas used for reception. If
you are 30 miles out to sea this is not a concern.

Hi Luc,
a linearly polarized antenna on a satellite means, that you will see
different polarization at different times and different locations on
Earth. Assume the satellites transmit vertical polarization but "tumbles"
then the polarization you are receiving is always linear but can vary
between vertical, diagonal, horizontal ...
Therefore it is better if the satellite and the station on earth both use
circular polarization. If this is not possible due to constraints on the
satellite I think it is still better to have a circular polarized antenna
at my station as the losses due to varying linear polarization will always
be only 3dB and thus no strong fading due to polarization will accur.
Please note that a tumbling satellite will most likely still generate strong
fading as the antenna on the satellite will never have a perfect
omni-directional behaviour.
Best regards

Hi Art,
this is a very good point. This is also one of the reasons why circular
polarization was chosen for the commercial GPS system.
