Hi,
Anyone know if these will have the RAW output for use with RTKLib?
I'm not sure exactly what's required for RTKLib, but you can read the
ublox protocol specs to know what informations are available.
Also assume can program for 10 MHz out?
Yes, but it's not necessarely a good idea.
The
Yes, but nonetheless why not develop more stable primary clock sources? We
can always take care of the dissemination in the meantime and try to
develop a more precise time transfer method.

I usually see GPS antennae flashed by lightning: have succedeed opening and
repairing a couple of them but at times they are too bad to do anything. I
use a network analyzer to test them after repairing here at work.

Agreed. My consideration was general but, yes, money is necessary so a
decision is a must to properly allocate the financial resources.

The Thunderbolt wants a higher gain antenna than most standard GPS
receivers. I tried standard Garmin active antennas, and while they
worked (I have a good view of the sky), signal levels could be better.

The Symmetricom item 300571554900 you listed below includes a GPS.
It is not just an antenna.

Thank you for your interest. I have checked many of the circuits which is
made easy in some cases because it is a duplication of the M100 in some
areas and the FRS in others. I have both for comparison. Do to the very high

The elevation angle filter is based on the satellite position, not the actual
direction the signals come from.
If you have reflections and multipath, but the satellite is otherwise high in
the sky, you are out of luck regardless of elevation angle filter.
Of course, the higher the sat, the
Of course the elevation mask is only software and doesn't prevent the bad
signal from entering the antenna but then the signal will not despread and
should cause no harm to the computations.

If the satellite is above the mask, the signal will be used in computing a
solution even if it got in through reflexions and multipath. That's why a good
antenna with choke rings is desirable.

Absolutely true, that's why it is advisable to dare with the elevation mask
and set it rather high (upto 20 deg?) if the antenna is clear above but
there is the possibility for multipath or reflections (i.e. surrounded by
buildings). Of course the choke rings antenna is better... guess how much
Typical chokerings are L1/L2 geodetic antennas. There is however simple
L1-only chokerings available from time to time on *bay. I have often seen
them as low as in the $50 range. Orginal use I think was for DGPS
reference stations. Most seem to be the Aeroantenna model in the url
below.
Yes, there was an antenna with the sting months ago, now that I see your
PDF I remember but can't remember the price and the brand.

that moisture got inside. Maybe I should try to take it apart? Not sure how
to open it without breaking the radome.
