| dc.description.abstract | In this thesis, the influence of the calculation interval length of scintillation indices calculated on Global Position System (GPS) signals, recorded at 100 Hz by high-latitude stations, is investigated and compared to results calculated at the commonly used 60 s calculation interval length. Individual cases and the statistics of multiple events, identified over a period of 16 months, are compared. I conclude that calculation intervals as small as 30 s yield results comparable to those obtained with a 60 s calculation interval. The acquisition rate of signals recorded by GNSS receivers is also investigated. High-rate receivers can resolve higher-frequency signal components, which are not predicted to be significant by theoretical scintillation models. An analysis of scintillation indices calculated on artificially decimated signals, emulating a lower receiver sampling rate, is performed. It is found that receiver sampling rates much lower than 100 Hz fully capture the features of scintillation events. | |
