摘    要:
测距仪标称精度一般是根据基线场上的检测结果确定的,由于仪器检测时的条件与工程现场条件不一致,因而标称精度不能反映观测实际精度,以标称精度定权处理观测数据,影响测量成果的质量;在工程实际中,若多余观测边较多,运用二次平差法进行测距仪精度估计,可正确反映仪器实际观测精度,为仪器性能判别及数据处理提供客观依据。

关 键 词:二次平差  测距仪  精度估计  测量平差

Abstract:
Two-times-adjustment has been pointed to estimate the accuracy of electronic distance-measuring instrument (EDM), compared with the traditional method which determined by the base-line site, where is not satisfying the real practical conditions, the result of the former is more useful to judge the quality of the EDM and more beneficial to data process.
Keywords:two-times- adjustment  EDM  accuracy estimation  adjustment
