Abstract
Abstract Based on the principle of satellite based augmentation information positioning, this paper uses the standard positioning algorithm of SBAS, IGMAS site data and augmentation information messages to evaluate the single point positioning performance of BDS satellite based augmentation information in China. From the results, the accuracy of single frequency augmentation information for single point positioning is improved by about 30%, which is equivalent to that of EGNOS. The accuracy of dual frequency augmentation information for single point positioning is improved by nearly 40%, which is better than that of single frequency.
