Spectrum analysis of the horizontal angle - measurement errors of theodolite

The component of errors during the horizontal angle-measurement of theodolite is analyzed. And the spectrum analysis is proposed for separation the variant errors more precisely. Error correction is introduced for the main component of the errors in measuring the horizontal angle. The result of experimental data analysis indicates that the method of spectrum analysis and error correction can get the error information more detailedly and reduce the uncertainty of measurement greatly during the measurement of theodolite, comparing with the classical method of limit error for single horizontal angle-measurement.
