A system for demodulation of the Loran Data Channel transmitted over the Enhanced Loran (eLoran) system including a quadrature filter. The quadrature filter calculates the real and quadrature phase components of a received ninth pulse. The resultant components are used to obtain the angle of the ninth pulse. This angle is then compared with a set of pre-tabulated angles/symbols that are calculated using the same quadrature filter on thirty-two different simulated ninth pulses. The closest angle match gives the corresponding symbol. Such twenty-four symbols make up a single Reed Solomon encoded message. This message is then passed through a Reed Solomon decoder and the transmitted message is obtained.
