APPARATUS AND METHOD FOR PSEUDO RANGE VERIFICATION OF GNSS RECEIVER

摘要

PURPOSE: A pseudo-range verification method of a satellite navigation receiver and an apparatus thereof are provided to analyze pseudo-range measurement distribution and pseudo-range accuracy, thereby analyzing errors generated during a pseudo-range measurement process. CONSTITUTION: A navigation data receiving part(210) receives navigational data from a satellite navigation receiver(110). A receiver location input part(220) receives the location of the satellite navigation receiver when measuring a pseudo-range for measurement. A satellite location calculation part(230) calculates the location of a navigation satellite which transmits a satellite signal using visual information and satellite signal data. A pseudo-range generation part(240) generates a pseudo-range for verification using the position of the navigation satellite and the inputted position of the satellite navigation receiver. A pseudo-range verification part(250) calculates a difference value of the pseudo-range for verification and the pseudo-range for measurement. The pseudo-range verification part determines an error of the satellite navigation receiver.
