中文摘要：

针对基线测量逐渐淘汰的现实,结合工作实际开展了用精密测距替代基线丈量的实用化研究与试验。通过测量误差分析,结合仪器性能和基线测量技术要求,在理论研究的基础上,进行了室内外大量测试,不断改进技术设计,修订操作规程,实现了基线测量技术的更新换代和数字化改造。6年多的监测实践表明,基线测量技术更新是成功的。

英文摘要：

In so much as the reality that the baseline measurement will be gradually falling into disuse,precise range measurement instead of baseline measurement is practically studied and tested.By means of the analysis of measurement error,the combination with the related equipment performance and its technical requirement,and on the basis of the study for theory,precise range measurements had been conducted numerously indoor and outdoor.In the meantime,its technical design is constantly modified,and its operational regulation is revised as well.As a result,the baseline measurement technique is updated and digitally remodified.The results of 6 years monitoring show that the updated baseline measurement technique is successful,the achievement is worth to be widely applied.
