Abstract

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.
