SATELLITE NAVIGATION AUGMENTATION SYSTEM AND SATELLITE NAVIGATION AUGMENTATION METHOD

摘要

as a satellite navigation system reinforcement , the carrier at the time the pseudorange measurement is based on a signal from a GPS satellite and a threshold calculating unit for calculating a threshold value for judging whether the display of the value of the power-to- noise power density ratio (C / No) whether proper, by comparing the C / No value and monitors the threshold, the appropriate pseudorange (v) a pseudo- distance judgment to determine whether it has the precision . ;
