Hi Bob,
I use the Trimble Thunderbolt as a 10 MHz reference.

One thing you would want to set up different from the receiver's
defaults is the elevation mask.
Hey, great info, thanks. I am getting one

time, I have to say it was pretty boring. Eventually both the standards broke

Bob,
You can use a 10 MHz Rubidium standard, or for even more accuracy, the
Trimble Thunderbolt.
The Thunderbolt requires a GPS antenna.

As far as I can see you can either use the ext ref continuously
(which was my plan) or you can use it as a very handy way

Hi Bob,
I use the Trimble Thunderbolt as a 10 MHz reference. This is a GPS disciplined
clock, using GPS as the main time reference and an OCXO. The time and 10 MHz
output are both very precise, in the 30 PPT range (though this precision
varies, but not by even an order of magnitude). You
