摘要:

我们报告了一个成功的7小时1.4 GHz VLBI实验的结果,使用两个新站,ASKAP-29位于西澳大利亚州和WARK 12 M位于新西兰北岛。这是第一次有这些新站参加的大地测量VLBI观测会议。我们已经确定了ASKAP-29和WARK 12 M的位置。位置估计的随机误差对于垂直分量为150-200 mm,对于水平分量为40-50 mm。未建模的电离层路径延迟引起的系统误差可能达到1.3米的垂直分量。

英文摘要:

We report the results of a successful 7 hour 1.4 GHz VLBI experiment using two new stations, ASKAP-29 located in Western Australia and WARK12M located on the North Island of New Zealand. This was the first geodetic VLBI observing session with the participation of these new stations. We have determined the positions of ASKAP-29 and WARK12M. Random errors on position estimates are 150-200 mm for the vertical component and 40-50 mm for the horizontal component. Systematic errors caused by the unmodeled ionosphere path delay may reach 1.3 m for the vertical component.
