Abstract

Abstract: The positioning errors sequences of FJCORS reference stations are analysed in the paper, it's found that the observation errors show obvious seasonal variation, and the peak value appears in July for each station. By analyzing the relationship between the positioning errors and ionospheric VTEC and meteorological elements respectively, it shows that the positioning error is not related to VTEC, but has a strong correlation with meteorological elements. The decrease of air pressure or the increase of air temperature and vapor pressure will directly lead to the linear increase of errors.

Key words: FJCORS, positioning error, seasonal variation, VTEC, meteorological elements
