Investigation of The Benifits of Multi-Chain Loran-C and Hybrid GPS/Loran-C Positioning

Although the user of GPS are increasing rapidly throught the world, satellite-only-solutions (GPS) cannot provide the integrity or availability necessary to be certified as a sole means of navigations. The hybrid system is being used to provide robust operation. Because of the development of modern digital Loran-C receiver, the performance of Loran-C increase significantly. The purpose of this paper is to present a new method to utilize the new digital Loran-C receiver's benifits to increase the Loran-C coverage while simultaneously reducing the integrity problem. It also shows the result of testing to support the new method can fit the idea of GPS/Loran-C partnership.
