    • Development of the compact VLBI system for calibrating GNSS and EDM devices

      Ichikawa, R; Ishii, A; Takiguchi, H; Takefuji, K; Ujihara, H; Koyama, Y; Kondo, T; Kurihara, S; Miura, Y; Kawabata, R; Kokado, K; Machida, M; Takashima, K; Fujisaku, J; Tanimoto, D; Nozawa, K (National Institute of Information and Communications Technology (NICT), 2010)
      We are developing a compact VLBI (Very Long Baseline Interferometry) system with 1.6 m diameter aperture dish in order to provide reference baseline lengths for calibration. The reference baselines are used to validate ...

    • Ultra-rapid UT1 measurement by e-VLBI

      Sekido, M; Takiguchi, H; Koyama, Y; Kondo, T; Haas, R; Wagner, J; Ritakari, J; Kurihara, S; Kokado, K (Terra Scientific Pub. Co., 2008)
      The latency of UT1 measurement with Very Long Baseline Interferometry (VLBI) has been greatly reduced by using e-VLBI technology. VLBI observations on the baseline formed by the Kashima 34-m and the Onsala 20-m radio ...
