Although GNSS is unquestionably the best radio navigation system, it can not be used wildly because its signal is weak and interfered easily. The research result shows that Loran-C should be viewed as an excellent complement to GNSS, and it has not yet reached its technological limit. Contemporary Loran-C receiver performance will be vastly improved in the next 10-20 years. For example, new receivers are all-in-view and track 30-35 Loran transmitters simultaneously in North America. A study on crucial techniques of Loran-C digital signal processing is carried out in this paper.Two approaches are studied in detail in this paper.
