Paper Abstract

The errors in GPS measurement generally consist of systematic error (such as clock bias, iron-sphere, trop- sphere effect, etc.), random error (such as measuring error) and outlier. Systematic error can be canceled by differencing technique or adding parameters into the equation system. Outlier may be detected by adding parameters or by statistic method such as expectation shifting or variance inflating. Because wavelet analysis has many good natures both in the time domain and in the frequency domain, as can automatically zoom in or out with different scales (frequencies), the arbitrary details of a signal can be observed and analyzed by the aid of Wavelet analysis. Based on the above features, Wavelet analysis is reputed as a mathematical microscope.
