GPS在工程控制测量应用中存在问题探讨

摘要

Being an important means of surveying and mapping technology, GPS has been widely used in the fields of surveying and map- ping now. Due to the frequent use of GPS in control survey, we would often encounter several issues of GPS technology. According to expe- rience of many years in survey, the author summarized these problems in this paper for reference.%当前GPS技术已经广泛地应用到测绘领域，成为测绘技术的一个重要手段。笔者所在单位由于经常使用GPS进行控制测量，使用GPS过程中经常会遇到一些GPS技术的问题。根据多年测量经验，现对这些问题作归纳总结，以供大家探讨。
