Abstract
The motion of the Minamitorishima Very Long Baseline Interferometry
station has been measured over the last five years in Western
Pacific VLBI Network experiments. The results of 16 independent
experiments indicated its steady motion of the station in the
horizontal projection plane. The estimated velocity was
70.9+/-3.0 mm/year toward N71.2+/-2.2W in
the latest IERS Terrestrial Reference Frame, ITRF93. The high
reliability and quality of the data obtained in the Western Pacific
VLBI Network experiments was demonstrated by the estimated
horizontal movement of the station being consistent with a
constant-velocity linear motion.
