GPS is becoming an important tool for structural monitoring. As the advent of the receiver with sampling rate as high as (100 Hz), there is no problem in structural frequency monitoring by GPS. But because GPS observation is contaminated by many errors sources, its accuracy needs to be improved to meet small structural amplitude monitoring. In this paper a new single epoch algorithm is presented by integrating wavelet analysis with combined single epoch algorithm to isolate various errors. Several experiments showed that the proposed algorithm is effective and efficient.
