Precise Point Positioning with integer ambiguity resolution
Orviská, Terézia ; Václavovic,, Pavel (oponent) ; Nosek, Jakub (vedoucí práce)
The aim of this diploma thesis is to compare the accuracy and time of convegence of the Precise Point Positioning (PPP) method and PPP with an integer ambiguity resolution and to asses the applicability of the PPP method in estimating earthquake magnitudes. The thesis describes the theoretical foundations of GNSS method PPP, important systematic errors and methods for their elimination. Subsequently, the solution to the practical part is presented. The data are processed from the period of 2020 using 14 selected permanent IGS stations. The PPP computation was preceded by a quality control. In the results, the PPP method with integer ambiguity resolution using uncombined observation exhibited the most consistent and accurate results with the fastest convergence. For magnitude estimation, three earthquakes from the Alaska region during the period of 2020-2021 were selected, and four combinations of methods were examined, with the best results once again provided by the PPP method with integer ambiguity resolution using uncombined observations.
