The Oncore driver will do all this for you. It is controlled by the
MODE parameter in /etc/ntp.oncore0. You can also download "WinOncore12"
from Motorola (there's a link at the Synergy web site). WinOncore12
will do a site survey with graphical output showing the data used; e.g.
all position points used to arrive at the calculated value. Typically
the reported positions will be within a circle with a radius of about
300 feet. You grab enough points to find the center of that circle.
WinOncore12 will also display a bar graph of satellite signal strengths
or a sky map of satellite positions. It's a very nice program to have.
