Space Based Augmentation Systems (SBAS) have been developed principally to augment the Global Positioning System (GPS) for aviation and other safety of life applications.
Many concepts have been proposed to increase the data rate of LORAN. Enhanced LORAN modulation schemes can provide many benefits to navigation including the transmission of GPS integrity information f...
