eLoran is an enhanced Loran-C which uses TOA measurements and improves navigation accuracy. TOA measurements of eLoran include some kinds of error factors and eLoran navigation algorithm can fail estimation of precise position due to these error factors. Therefore, in order to improve navigation performance of eLoran, all error factors of TOA measurements must be compensated. But compensation of some biases like ASF, clock bias and unknown biases are so difficult and requiring large memory, while PF or SF can be easily calculated. Therefore, this paper proposes GPS aided error compensation method. GPS aided error compensation method is using true range that calculated with receiver position and eLoran station using GPS solution. Proposed method can compensate all error factors simply included in TOA measurements of eLoran. In this paper, raw measurements measured in Europe are used to verify proposed method and navigation algorithm. This raw data is compensated with calculated errors using combination of typical or proposed method.
