Antenna Graphics with Dimensions
Pictures for most of the antennas given here are available at the NGS
on the WWW page:
http://www.grdl.noaa.gov/GPS/PROJECTS/ANTCAL/antcal.html
The L1 and L2 antenna phase center offsets given in these drawings here
are manufacturer values and should not be used anymore. The official IGS
set of mean offsets and elevation-dependent phase center variations are
given in the file IGS_01.PCV.
