TL;DR: In this paper, a comprehensive statistical assessment of static PPP using GPS-only, GLONASS-only and GPS/GLONASS combined data was performed in a short (hourly to daily) and a long (several weeks) term, spanning observations from eleven IGS stations, revealing insignificant differences in the accuracy and repeatability among the three satellite constellation solutions for long (8 h, 24 h) observation times.

TL;DR: In this article, the authors evaluate the dynamic behaviour of the Ermenek Dam, the second highest dam in Turkey, based on conventional geodetic measurements and Finite Element Model (FEM) analyses during it.

TL;DR: In this paper, the structural behavior of the Ermenek arch dam, the second highest dam in Turkey, is studied. And the pendulum-derived displacements at four gallery levels, along the vertical cross section of the dam, which exhibit periodicity and linear trend with different slope due to seasonal temperature oscillation and linearly increased reservoir level, respectively.

TL;DR: In this article, simultaneous-reciprocal trigonometric levelling (SRTL) method is applied with different sight distances in order to determine optimum sight distances using a sample test network in Selcuk University Campus, Konya, Turkey.

TL;DR: In this article, a trigonometric line with 11 points was established in Alaeddin Keykubat Campus area of Selcuk University and three separate geometric levelling with different three equipments (Wild T2 theodolite for vertical angle measurements and Topcon GTS 701 electronic total station for distance measurements) and GPS/levelling (with Leica 9500 receiver) were used.
