文摘The redundant observation, error tolerances, adjustment and precision estimation are the methodology of surveying technology, which are used in the procedure of survey engineering. Based on a redundant observation magnitude of experiments, a guideline system of precision for GPS total stations is established to prescribe the methods of redundant observation, the computation formulas of error tolerances and standard errors. Moreover, a series of precision indexes for GPS total station measurements and results are also acquired from the comparative experimentations and study on the observation data between GPS total station elevation and direct leveling.
