GSI’s regional stations and AOV activities

Ryoji Kawabata, Geospatial Information Authority of Japan Takahiro Wakasugi, Geospatial Information Authority of Japan

The Geospatial Information Authority of Japan (GSI) has been operating three VLBI telescopes, i.e. Tsukuba 32-m, Aira 10-m, and Chichijima 10-m telescopes. These stations have observed many IVS regular sessions including Japanese domestic sessions (JADE sessions). Some other Japanese stations have also participated in the JADE sessions. However, GSI determined to finish VLBI observation at Aira and Chichijima site by March 2015. Therefore there will be no JADE session from April 2015. Instead, GSI will devote their effort to the newly established Asia-Oceania VLBI Group for Geodesy and Astrometry (AOV) in operation, correlation, and analysis. Tsukuba 32-m and Ishioka 13m are going to observe six AOV sessions in 2015. We will report on the current status of GSI’s regional stations and AOV activities for GSI.
