PSEUDO DISTANCE EVALUATION SYSTEM, PSEUDO DISTANCE EVALUATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a pseudo distance evaluation system, a pseudo distance evaluation method, and a pseudo distance evaluation program for rapidly specifying the cause of an abnormal value when a pseudo distance subjected to real-time smoothing processing shows the abnormal value in positioning calculation in a satellite positioning system.;SOLUTION: The system includes a data processing part 2 which checks, when an abnormal value is detected from a pseudo distance after real-time smoothing processing to be used for positioning calculation, whether a pseudo distance after post-process smoothing processing at the same observation time of the abnormal value is a normal value or not, and determines, when the distance is the normal value, that the cause of the detected abnormal value is residual noise due to the limitation of real-time smoothing processing.;COPYRIGHT: (C)2010,JPO&INPIT
