Here are two toys for those NTP users that have ONCORE GPS receivers.
They work with the new SHMEM interface in refclock_oncore.c

I wanted to monitor SA, and the only tool I had to do this was SAWatch,
which ran under Windows.

The first program, sat_path, brings up an X window that shows the positions
of the satellites overhead, and it draws the path of the calculated position
(xy) of the station as it moves around with SA.

The plot keeps track of your input value for the (xyz) of the antenna, and
computes a ongoing Delta(xyz) which is presented at the bottom of the screen.
You could use this to update you idea of your antenna position.

The second program, horizon, draws streaks for the satellites as they cross
the sky, and then draws an envelope around these tracks.  After about a day
you will have a pretty good idea what your Horizon looks like.  You will also
see area near the pole where the satellites never venture.

Both programs can print Postscript versions of what is on the screen to lpr.

Thats about it, enjoy
