摘要

在前面的文章中已经表明,其GNSS天线放置在建筑物或其他结构上的永久EPN / IGS站的位置可能具有非地球动力学的单个季节性(一年)、自发(持续数天至数周)和日变化。研究还表明,它们可能是由建筑物或其他结构在环境温度变化的影响下的胀缩效应引起的。上述效应的典型特征通过一些永久EPN / IGS站的行为表现出来。本文继续进行研究。图中显示了受这种影响的一组EPN台站。这种效应的其他特征被发现改变了电台的行为。这种影响在新的情况下显现出来。指出了一种降低台站位置对温度依赖性的方法。

Investigating the ambient temperature influence on the positions of EPN/IGS stations located on buildings and other structures
It was shown in the preceding articles, that the positions of permanent EPN / IGS stations, whose GNSS antennas are placed on buildings or other structures, can have non-geodynamical individual seasonal (with a period of one year), spontaneous (lasting from several days to several weeks) and diurnal variations. It was shown too, that they may be caused by an expanding-contracting effect of the buildings or other stuctures under influence of ambient temperature changes. Typical features of the mentioned effect were displayed through behaviour of some permanent EPN / IGS stations. This paper continues the investigating. A set of EPN stations affected by this effect was shown. Additional features of this effect were found that change the stations` behavior. New situations are revealed in which this effect manifests itself. A way to reduce temperature dependence of stations positions was noted.
