Gps-derived Local Tec Mapping over Peninsula Malaysia during Solar Minimum of Sunspot Cycle 24
The ionosphere is the major contributor of errors in Global Positioning System (GPS), especially during the 11-year sunspot cycle. The incoming 11-year sunspot cycle is expected to peak in 2013. The ionosphere condition is distinctly severe during ionospheric disturbances caused by high solar activity, which raises the question of how will this affect the ionosphere in the equatorial region, es...
متن کاملGPS phase scintillation and proxy index at high latitudes during a moderate geomagnetic storm
The amplitude and phase scintillation indices are customarily obtained by specialised GPS Ionospheric Scintillation and TEC Monitors (GISTMs) from L1 signal recorded at the rate of 50 Hz. The scintillation indices S4 and σ8 are stored in real time from an array of high-rate scintillation receivers of the Canadian High Arctic Ionospheric Network (CHAIN). Ionospheric phase scintillation was obser...
متن کاملStudy of GPS scintillation during solar maximum at Malaysia
The global positioning system (GPS) is one of the most important and useful technology that has been developed for information and communication technology. The propagated wireless signals along GPS link are affected by the ionospheric electron density irregularities, so the GPS signals may experience amplitude and phase fluctuations. The global navigation satellite system (GNSS) ionospheric sc...
متن کاملIonospheric Scintillation Effects on GPS Receivers during Solar Minimum and Maximum
The ionosphere has practical importance in GPS (Global Positioning System) applications because it influences transionospheric radio wave propagation. Among various phenomena in the ionosphere, ionospheric scintillation is characterized by rapid fluctuation and fading of the received signal intensity due to electron density irregularity inside the ionosphere. Deep signal fading caused by scinti...
متن کاملClimatology of GPS phase scintillation at northern high latitudes for the period from 2008 to 2013
Global positioning system scintillation and total electron content (TEC) data have been collected by ten specialized GPS Ionospheric Scintillation and TEC Monitors (GISTMs) of the Canadian High Arctic Ionospheric Network (CHAIN). The phase scintillation index σ8 is obtained from the phase of the L1 signal sampled at 50 Hz. Maps of phase scintillation occurrence as a function of the altitude-adj...
