A Gigabit per second Data Recording System for Geodesy and Astronomy

用于大地测量和天文学的每秒千兆数据记录系统。我们计划为大地测量学和天文学获得一个每秒千兆比特的数字数据记录器。我们将开发大地测量VLBI能力，为GPS和单反等替代技术的结果提供独立确认，并允许我们描述和消除这些系统固有的系统误差。我们将结合VLBI、GPS、重力和潮汐计数据来估计站点的运动，以获得冰川后反弹、构造运动和全球平均海平面变化等地球动力学效应。我们将增加用于定义国际天体参考系的南方射电源的密度，并研究它们的结构和演变。我们将对年轻脉冲星进行高时间分辨率的观测，以研究脉冲星故障现象，并帮助了解中子星内部。

A Gigabit per second Data Recording System for Geodesy and Astronomy. We plan to acquire a gigabit per second digital data recorder for geodesy and astronomy. We will develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems. We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic effects, such as post-glacial rebound and tectonic motion and global mean sea level change. \r\nWe will increase the density of southern radio sources used to define the International Celestial Reference Frame and investigate their structure and evolution. We will make high time resolution observations of young pulsars to study the phenomena of pulsar glitches and aid in the understanding of neutron star interiors.
