Özet
If points of interest cannot be observed with permanent GPS stations, repeated GPS measurements are used as an economical alternative. In this study, quality of results derived from repeated GPS measurements are analyzed. Repeated GPS measurements are collected at 7 points annually from 2011 to 2013. For the analyses, Canadian Spatial Reference System Precise Point Positioning (CSRS-PPP) which is an online GPS data analysis server is used. Additionally, 2.5 h, 5 h and 24 h GPS static data is processed using CSRS-PPP service to be used as reference for comparison purposes. Our results indicate that with short span data less accurate results are obtained. As the observation period gets longer, variations in the range of observations get smaller i.e., better results are obtained.
