| 抄録 | GALAXY is a research project on advanced VLBI technology, jointly conducted by CRL, NAO, and NTT. The testbed of the project is a 2.5-Gb/s ultra-high speed network using Asynchronous Transfer Mode (ATM). One of the aims of this project is to achieve high-sensitivity VLBI observation with this gigabit class network. GALAXY network consists of KSP and OLIVE networks provided by NTT and spans 200 km range. The sensitivity achieved in the current observation system is comparable to the world highest class (approximately 10 mJy) using conventional VLBI samplers. This short baseline and high-sensitivity make GALAXY a unique VLBI network for astronomy in the world. Here is described the properties of GALAXY network and observations focusing on some unique results that can be achieved with the capability of GALAXY. Developments of new networking technology such as Internet Protocol (IP) with GALAXY network are also presented. |
