Research Abstract

本研究では、国際測地VLBI網の高精度化のために、超高速光回線を用いたe-VLBI方式の技術開発を行なった。これまでに我々はスーパーSinetを用いて2GHz帯および8GHz帯による2周波同時e-VLBI観測を行い、測地解を導くシステムを構築している。本研究では次期測地VLBIとして検討が進められているVLBI2010システムの基礎技術として22GHz帯による高周波測地e-VLBI観測を行った。岐阜大学11m電波望遠鏡の受信機を22GHz化し、情報通信研究機構・鹿島34m電波望遠鏡とのe-VLBI観測テストに成功し、また国立天文台のVERAプロジェクトの3台の20m鏡との測地e-VLBI観測に成功した。
