Application of a damping function in adjustment of GPS networks with long vectors

Autor(en): Tadeusz Gargula

The aim of this study is to examine the effect of long GPS vectors on the precision of determination in monitoring terrain dislocation. The results will be processed numerically with the classical method of least squares and with selected damping functions [5, 6]. In the latter case, selection of the appropriate criteria of the damping function will be an important issue [7]. The study is based on the actual results of measurements performed in a landslide in Siercza near Krako´w. Apart from the measurements by the static GPS method, classical situational and height measurements were performed for comparison. The results are taken from one periodic measurement (cycle). The comparative analyses are based on the results of adjustment of satellite (GPS), classical (on-the-ground) and integrated (classical measurements with GPS observations) networks.
