4-station ultra-rapid EOP experiment with e-VLBI technique and automated correlation/analysis

• Since 2007, the Geospatial Information Authorityof Japan (GSI) and the Onsala Space Observatory(OSO) have performed the ultra-rapid dUT1 experiments,which can provide us with near real-timedUT1 value. Its technical knowledge has already beenadopted for the regular series of the Tsukuba-Wettzellintensive session. Now we tried some 4-station ultrarapidEOP experiments in association with Hobart andHartRAO so that we can estimate not only dUT1 butalso the two polar motion parameters. In this experimenta new analysis software c5++ developed by theNational Institute of Information and CommunicationsTechnology (NICT) was used. We describe past developmentsand an overview of the experiment, and concludewith its results in this report.
