APPARATUS AND METHOD FOR REDUCING IONOSPHERE ERROR IN SMOOTHING FILTER BY USING IONOSPHERE CORRECTION INFORMATION

摘要

The present invention discloses an apparatus and method for reducing an ionosphere error of a smoothing filter using ionospheric correction information of a satellite-based correction system. According to an embodiment of the present invention, the apparatus for reducing an ionospheric error in a smoothing filter includes a calculation part for calculating an ionosphere error variance, and an attenuation processing part for attenuating the ionospheric error of the smoothing filter using the calculated ionosphere error variance.
