The Phase-Locked Loop (PLL) is a key component of modern electronic communication and control systems. PLL is designed to extract signals from transmission channels. It plays an important role in systems where it is required to estimate the phase of a received signal, such as carrier tracking from global positioning system satellites. In order to robustly(More)
Aircraft navigation based on GPS (Global Positioning System) and WAAS (Wide Area Augmentation System) requires both code and carrier measurements to calculate the position estimate [1]. A GPS receiver's carrier tracking loop is weaker than code tracking loop. Thus, carrier lock can more easily be broken under deep signal fading caused by ionospheric(More)

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(More)
