The Gill Creek antenna near Fairbanks Alaska. This antenna is operated by the NASA geodesy group at GSFC. It is very active in geodetic VLBI, probably one of the most active VLBI stations in the world. We visited it after a three week canoe trip on the Noatak river in Northwest Alaska. One unique characteristic is the XY mount which avoids the dead spot at the zenith characteristic of ALTAZ mounts. |
