How to verify the ADAM GPS units are getting satellite lock via Gordon feedback
FYI, "ntpq -p" from aster is a good check of the network and GPS's. This shows
that all the adams are happy (with either a leading * or +) except for pressure2
which is getting its clock from the base.
[aster@aster ~]$ ntpq -p
