The Millimeter Accuracy of the Geodetic VLBI Measurements Achieved on a 54-KM Base Line

The millimeter accuracy of the geodetic VLBI measurements was demonstrated in the experiments repeated 4 times on a 54-km baseline between a 5-m transportable antenna at Tsukuba and a 26-m antenna at Kashima. The error analysis shows that the thermal reeeiver noise is a main cause of the delay observation error and the atmospheric fluctuations mainly affect on the delay rate observations.
