Zusammenfassung:	PURPOSE: An eLORAN receiver and a positioning method of an eLORAN receiver are provided to improve positioning performance by effectively removing an error included in an eLORAN measurement value. CONSTITUTION: An eLORAN receiver(700) includes a reception unit(710), a distance measurement unit(720), and a location estimation unit(740). The reception unit receives each signal transmitted from more than 4 LORAN transmitters. The distance measurement unit calculates a measurement distance by multiplying the speed of light with time difference between a transmitted signal and a received signal. The location extraction unit calculates a location based on each measured distance and coordinate of a reference point, a clock error at the reference point and an unknown variable at the reference point.
