本报告总结了在开发下一代VLBI2010系统方面取得的进展。2010年VLBI2010国际大地测量和天体测量局委员会致力于新系统的设计方面的工作。该报告包括蒙特卡洛模拟，展示了新的运行模式对最终产品的影响。系统注意事项一节通过考虑新模式和与系统相关的问题(如灵敏度、天线转换率、延迟测量误差、RFI、频率要求、天线变形和源结构校正)，描述了对VLBI2010系统参数的影响。接下来是对所有主要子系统的描述以及对网络、站点和天线的建议。然后介绍馈电、极化处理、校准、数字后端和相关器等子系统。有一部分专门介绍NASA的概念验证演示。最后，关于业务考虑、风险和后备选择以及下一步的章节完成了报告。
This report summarizes the progress made in developing the next generation VLBI system, dubbed the VLBI2010 system. The VLBI2010 Committee of the International VLBI Service for Geodesy and Astrometry (IVS) worked on the design aspects of the new system. The report covers Monte Carlo simulations showing the impact of the new operating modes on the final products. A section on system considerations describes the implications for the VLBI2010 system parameters by considering the new modes and system-related issues such as sensitivity, antenna slew rate, delay measurement error, RFI, frequency requirements, antenna deformation, and source structure corrections. This is followed by a description of all major subsystems and recommendations for the network, station, and antenna. Then aspects of the feed, polarization processing, calibration, digital back end, and correlator subsystems are covered. A section is dedicated to the NASA proof-of-concept demonstration. Finally, sections on operational considerations, on risks and fallback options, and on the next steps complete the report.
