The main objective of this study is to compensate channel distortions in GPS-Aided GEO Augmented Navigation (GAGAN) applications by means of adaptive equalization. Positional accuracy of GAGAN system is basically dependent on ranging errors and satellite constellation geometry. Further, this study focuses on enhancing the phenomena of instrumental biases and GAGAN augmentation.
