The QueSERA Study Group (QSG) have been tasked by the RadioNet Board to produce a White Paper on the future organisation and coordination of radio astronomy in Europe. This White Paper describes the options discussed by the QSG, and our conclusions on how to move forward. We propose, that as a first step, RadioNet-work, be established as an entity that persists between EC contracts, and that takes responsibility for preparing or coordinating responses to EC opportunities specific to the field of radio astronomy research infrastructures. RadioNet-work should provide a safety net that ensures that cooperation and collaboration between the various radio astronomy partners in Europe is maintained with or without EC funding.
Kiwi Advanced Research and Education Network(KAREN)已被用于在新西兰Warkworth的AUT射电天文台与我们合作和进行观测的国际组织之间传输大量射电天文数据。在这里,我们报告了连接的当前状态和测试不同数据传输协议的结果。我们研究了新的UDP协议,如“海啸”和UDT,并证明了UDT协议比“海啸”和FTP更有效。我们报告我们的初步步骤,实时eVLBI和尝试直接流数据从射电望远镜接收系统的相关中心没有中间缓冲/记录。
Radio astronomy and Space science in Azores: enhancing the Atlantic VLBI infrastructure cluster
亚速尔群岛的射电天文学和空间天文学结构具有巨大的科学和工业利益,因为它们受益于北大西洋中部的独特地理位置,从而大大改善了天空覆盖范围。这一事实显然具有非常高的附加值:一)为新兴的全球小型卫星群建立空间跟踪和通信网络;二)使用甚大基线干涉测量技术将非洲、欧洲和美洲大陆的射电天文学基础设施网络连接起来,这是非常宝贵的;三)它为监测空间碎片和近地物体提供了巨大的潜力。在S。米格尔岛是一个32米长的卫星通信天线,可以集成在先进的VLBI网络中,并能够提供额外的深空网络地面支持。本文探讨了S. Miguel 32米卫星通信天线将成为射电天文学和空间探索的世界级基础设施:它将启用深空网络模式,并将构成数据制作、促进当地数字基础设施投资和尖端信息技术测试的关键空间设施。它的大西洋位置还可以提高角分辨率,在东西和南北方向提供许多基线,将美洲的应急VLBI站与欧洲和非洲VLBI阵列连接起来,因此有助于提高阵列成像能力,特别是对接近或低于天球赤道的源或研究良好的场,ESO设施,ALMA,SKA及其前身在未来几十年内正在或将继续运行和观测。
