Abstract: The global navigation satellite system (GNSS) ionospheric scintillation and total electron content (TEC) monitor (GISTM) receiver has been installed at UTeM, Malaysia (2.3139 °N, 102.3183 °E) for the purpose of monitoring ionospheric scintillation. Ionospheric scintillation data has been collected during solar maximum cycle 2013-2014 for six months. Solar activities significantly impact the ionospheric GPS scintillation, especially in the equatorial region where Malaysia is located. The GPS link is analysed to investigate how the scintillation increases during the solar maximum cycle. The total electrons increased in the ionospheric layer and the scintillation values gradually. In this paper, the GPS ionospheric scintillations are concerned for the dual frequency L1 (ƒL1 = 1.57542 GHz), and L2C (ƒL2 = 1.2276 GHz). The ionospheric amplitude/phase scintillation of GPS satellites is reported. Finally a new algorithm is suggested to enhance the GPS positioning system with availability of GPS and precise point positioning (PPP) approach.

Keywords: global positioning systems; GPS satellites; ionospheric scintillation; precise point positioning; Malaysia.
