4-station ultra-rapid EOP experiment with e-VLBI technique and automated correlation/analysis
Conference contribution, 2013
Since 2007, the Geospatial Information Authority
of Japan (GSI) and the Onsala Space Observatory
(OSO) have performed the ultra-rapid dUT1 experiments,
which can provide us with near real-time
dUT1 value. Its technical knowledge has already been
adopted for the regular series of the Tsukuba-Wettzell
intensive session. Now we tried some 4-station ultrarapid
EOP experiments in association with Hobart and
HartRAO so that we can estimate not only dUT1 but
also the two polar motion parameters. In this experiment
a new analysis software c5++ developed by the
National Institute of Information and Communications
Technology (NICT) was used. We describe past developments
and an overview of the experiment, and conclude
with its results in this report.
