摘要
对1979～1997年间测地VLBI资料，按测站网的观测时段、观测次数、台站组成和地理分布等特性进行了统计。
Statistical results of geodetic VLBI observations from 1979 to 1997 are shown in Table 1 and 2 andFigure 1 and 2. From left to righ row of Table 1 are the names of station networks, the start and (statistical) final observation epochs, the number of sessions, the number of stations and the codes of stations.Those in Table 2 are the codes, the names, the geocentric and Ihe geopohical coordinates of stations.The global distribution of these stations are shown in Figure 1 and the geographical coverage of some selected station networks are shown in Figure 2. The statistics is helpful to us to have a overall look of thegeodetic VLBI observations, to design and select parameters in global or regional observation reduction.
