Abstract :
This paper presents software receiver processing results of GPS L1, L2C, and L5 signals undergoing strong ionosphere scintillation. The data used in this study were obtained from a multi-GNSS multi-band IF data collection system at Ascension Island in March 2013. Detailed signal processing algorithms and scintillation indices calculated from carrier tracking loop output such as S4 and σφ are presented and the results are compared with the output of a co-located Septentrio PolaRxS receiver.
