Modulation Schemes for the Eurofix Datalink

In the Eurofix system DGPS corrections are transmitted using the Loran-C signal as a datalink by time shifting the Loran-C pulses. The performance of the datalink, however, is bounded by restrictions of both the Loran-C system and the DGPS system. First, the normal Loran-C performance should not degrade noticeably due to the extra data...

An Advanced Loran-C receiver

Since Loran-C is a widely used system and a potential candidate in the integrated navigation systems of the future, there is a need for faster and more sophisticated Loran-C receivers. The problems of conventional Loran-C receivers are mainly caused by skywave interference, carrier wave interference and cross rate interference. A new approach...
