There are a lot more than a dozen antennas that are characterized. See http://www.ngs.noaa.gov/ANTCAL/index.shtml for the small list. A larger number of calibrations are available from Geo++ http://geopp.de/index.php?bereich=5&kategorie=34&artikel=62 but the data from Geo++ is not for free. Your postprocessing software might already have some of the Geo++ data. Note that NGS normaly give Relative corrections (compared with the "golden standard" an AOA JPL chokering iirc) Geo++ often give absolute corrections. -- Björn _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
