영문 초록

The Loran C position accuracy is not excellent but the repeatable and relative accuracy is very good, and it is very useful for fishing vessel in coastal waters. The operation of Korea chain(GRl 9930) was begun on January, 1996, and in order to evaluate the accuracy of this chain, it was observed with Loran C receiver (LC-90, Furuno) in June 26, 1997 at the fixed position of Kunsan national university. The obtained results were as follows; The time difference error of M-W, M-X, M-Y pair were 1.29 ㎲, 0.13 ㎲, 2.07㎲ respectively and the mean time differences of M-W, M-X, M-Y pair were 11495.51 ㎲, 28262.33 ㎲, 43150.21 ㎲ respectively. And the mean position error of W-X, W-Y, X-Y were about 859 m, 560 m, 612 m respectively
