A Gigabit per second Data Recording System for Geodesy and Astronomy

用于大地测量和天文学的千兆位每秒数据记录系统。我们计划购买一台用于大地测量和天文学的每秒千兆位数字数据记录器。我们将开发大地测量VLBI能力，以提供对GPS和SLR等替代技术结果的独立确认，并使我们能够表征和消除这些系统固有的系统误差。我们将根据VLBI、GPS、重力和验潮仪数据的组合来估计地点的运动，以了解地球动力学效应，如冰川后反弹和构造运动以及全球平均海平面变化。\r\n我们将增加用于定义国际天球参考架的南方射电源的密度，并调查它们的结构和演化。我们将对年轻的脉冲星进行高时间分辨率的观测，以研究脉冲星毛刺现象，并帮助理解中子星内部。

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.
