PHASE OFFSET PREDICTING METHOD OF A GLOBAL SATELLITE NAVIGATION SYSTEM, SATELLITE SIGNAL INTEGRITY EVALUATING METHOD USING THE SAME, AN EVALUATING DEVICE, AND A RECORDING MEDIUM CAPABLE OF ACCURATELY MEASURING A DISTANCE, A LOCATION, AND TIME

摘要

PURPOSE: A phase offset predicting method of a global satellite navigation system, satellite signal integrity evaluating method using the same, an evaluating device, and a recording medium are provided to set a prediction interval of a phase offset value and determine whether or not of a clock abnormality of an atomic clock mounted in a satellite by using the measured phase offset value and a predicted phase offset value.;CONSTITUTION: A receiver(120) receives a satellite signal from a satellite(110). The receiver detects a clock signal. A calculating device(130) calculates a phase offset value based on the clock signal. The calculating device predicts a prediction phase offset value based on the calculated phase offset value. The calculating device compares the phase offset value and the prediction phase offset value. The calculating device evaluates satellite signal integrity.;COPYRIGHT KIPO 2013;[Reference numerals] (10) 1-second signal; (120) Receiver; (130) Calculating device; (140) Atomic clock
