Abstract
A medium frequency (MF) radio system is being developed worldwide for the broadcast of differential corrections to users of GPS. These DGPS radiobeacons use groundwave propagation to carry the DGPS corrections to well beyond the radio horizon where the DGPS data is still valid. The International Association of Lighthouse Authorities (IALA) has established an international standard for the DGPS radiobeacon signal. Member countries have been extremely active in the development and installation of working systems. In particular, Iceland has just completed a nationwide DGPS service based on these radiobeacons and the IALA standard. This paper details the Icelandic goals and objectives for DGPS. It describes the resulting system architecture, including reference stations, integrity monitors, communications, and system control. It also predicts system performance in terms of coverage and availability. The paper then describes the validation effort, including sea, airborne, and overland trials. Finally, it provides a summary and conclusions.
