论文摘要
2019年是国际VLBI测量和天文传统服务（IVS）20周年。这项服务是最大，最权威的组织，该组织协调了射射线标准和VLBI子系统的国际活动。目前，位于各大洲许多国家的大约60个天线参加了IVS观察计划。 IVS数据中心在超过17000次会议期间积累了超过1800万个观察结果，其中包括10,000多个密集型会议，以快速确定通用时间。本文基于1979 - 2018年期间IVS数据中心收集的一系列观测值的统计处理，追溯了IVS开发的动力学。这些年份，电台，基准和无线电来源的各种统计数据得到了。考虑了IVS观察数据的演变以及从处理VLBI观察获得的结果的准确性。
2019 marked the 20th anniversary of the International VLBI Service for Geodesy and Astrometry (IVS). This service is the largest and most authoritative organization that coordinates international activities in radio astrometry and VLBI sub-system of space geodesy. Currently, about 60 antennas located in many countries on all continents participate in the IVS observing programs. The IVS Data Centers have accumulated more than 18 million observations obtained during more than 17'000 sessions, including more than 10,000 Intensive sessions for rapid determination of Universal Time. The paper traces the dynamics of IVS development based on statistical processing of the array of observations collected in the IVS Data Centers for the period of 1979-2018. Various statistics by the years, stations, baselines, and radio sources are provided. The evolution of the IVS observational data and the accuracy of results obtained from processing VLBI observations is considered.
