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.
