DGNSS Reference Station and method of estimating a User Differential Range Error thereof

摘要

The present invention raw information including pseudorange correction information and distance relates to the reference station apparatus of the satellite radio navigation reinforcement system that calculated by broadcasting the error estimate, receives the transmitted signal from the satellite via the antenna pseudoranges and a receiver for outputting, to provide pseudorange error information including the pseudorange correction information generation section for generating a pseudo range correction information from the source information that is output from the receiver, and ionospheric signal delay information for the satellite, the troposphere signal delay information pseudorange error information provider, and calculating the average line rate of change for the pseudorange error information, and obtain the flattened value flattened for flattening interval set the pseudorange correction information using the calculated pseudo-distance error information mean line rate, leveling value the distance error and a calculation unit for calculating an estimated distance error estimate for the pseudo range correction information using. According to the distance error estimation value calculated for these satellite radio wave reference station apparatus and a thereto applied pseudoranges navigation reinforcement system correction information, pseudorange correction information by accurately estimating the distance error, regardless of the variation single satellite radionavigation reinforcement system reference station improving the reliability and service information of the correction, it provides an effect to enhance the availability. ;
