With regard to Angie Moore's IGS Mail #4463, please note that the U.S.
National Geodetic Survey operates a facility to calibrate the phase
patterns of GPS antennas, either with or without radomes.  For further
information, refer to <www.ngs.noaa.gov/ANTCAL/>.  The measurements are
the source of much of the information in the IGS calibration file
<ftp://igscb.jpl.nasa.gov/pub/station/general/igs_01.pcv>.

Station operators or GPS equipment manufacturers planning to deploy new
or uncalibrated antennas are invited to use this calibration service.
Whenever possible, it is preferable to test multiple samples of the same
model.  There is no fee charged for the testing, but we do ask that the
return shipping charges be paid by the sender.

For further information, please contact me at the address below.
