Monitoring System for the Superconducting Gravimeter at the Syowa Station, Antarctica

Abstract

A communications satellite (INTELSAT) data receiving system with a 7.6m-diameter parabolic antenna was installed at Syowa Station in February 2004. We have carried out communications with the Antarctica station using a virtual private network (VPN) employing a S-Box. We began operation of a real-time monitoring system from Japan on August 26, 2004. The earthquake that recently occurred in Sumatra, Indonesia was observed from Japan using the superconducting gravimeter at Syowa Station.
