Abstract
A method for processing navigation signals received by a LORAN-C receiver to lessen the effects of noise on the navigation data provided to the receiver user. Time of signal arrival information measured by the receiver is modified depending on the signal-to-noise environment to remove extreme time of signal arrival deviations that are obviously erroneous. The modified information is then averaged to more accurately determine the true time of signal arrival and thereby provide more stable and accurate navigation data.
