We have an EndRun Technologies Praecis Gntp time server as one of our
two NTP appliance systems.  The specifications of the Unison GPS model
are very much the same as the Praecis Gntp.  It looks to me like the
Unison has replaced the Praecis in their current product line.

The good news is that the product works great for us.  We installed it
just over two years ago, and it has performed very well in our network.
 About 100 systems use it over our internal network.  The "bad news" is
that it has functioned so flawlessly that the only support we've even
tried to use is to download and install the firmware updates

Here's the typical output of the ntpq peers and rv commands:
