| Summary: | Global Positioning System (GPS) is a navigation and precise-positioning tool. In
the scientific community, GPS plays an important role in the Earth sciences. There are
many type of GPS applications and usage. In this project, GPS being used to analyze
the scintillation of GPS signals at the Wireless and Radio Science Centre (WARAS)
Research Centre UTHM. The GPS signal propagate through the ionosphere, it will be
scintillated. Ionosphere scintillation is a rapid fluctuation of GPS signal’s phase and
amplitude. This is due to the content and the formation of the ionosphere over the
equatorial region. By using GPS receiver in WARAS, the scintillation effect of the GPS
signal will be determined. Then, the scintillation effect will be analyzed under the three
conditions like the data before the GPS antenna have been removed, the data after the
GPS antenna have been removed and the data on rainy days. By doing so, the
relationship between the variation of the ionosphere over the region with the
scintillation to the GPS signal will be known. Overall, the scintillations parameter of the
GPS signals was identified using the amplitude and phase scintillation. Each of the
parameter will verify using the effect of scintillation at C/No, S4cor
, ambient noise,
thermal noise and elevation angle. |
