摘要：
Based on 138 evenly distributed IGS coordinate time series spanning more than 10 years, site-to-site coefficents in large scale GPS network were analyzed. Their site-to-site coefficients indicate significant corelationship even when the between-site distance more than 5 000 km. Therefore, this paper proposes a new method introducing coefficients as weight factor to calculate common mode error, and it improved the correlation-based spatial filtering technique. Time series from global and regional networks were used to verify this new method. The results show that this improved coefficient-based spatial filtering technique overcomes the spatial scale limit and effectively extracts common mode error of GPS coordinates time series.
