摘要随着现代的测绘技术的高速发展，传统的测绘方法虽然在精密测量上有很大的优 势，但是它不适合进行大范围的全球性的联合观测，GPS 测量就可以很好的完成大面积 的测量。GPS 测量技术能够建立显示全球的大地控制网，并且可以提供精准的坐标系统。 GPS 测量技术在现代测绘技术中占有非常重要的角色[1]。69942
本文就是主要来讨论 GPS 外业测量及其质量的检核。在 GPS 测量中，外业测量又是 不可或缺的部分，为了保证 GPS 外业测量中的误差能够及时的被发现，提高整个外业测 量工作的效率，完好的实现外业测量的数据质量检核，是达到定位精度要求的重要部分。 通过对大三学期 GPS 外业测量实习的数据成果进行重复边检核，同步环检核和异步环检 核。根据这几个方面来检查 GPS 外业测量实习成果的检核。在进行数据处理与分析后， 对不符合精度要求的基线边。则需要进行野外的返工测量。直至达到测量成果检核的要 求。

GPS external observation quality check
Abstract With the rapid development of the modern surveying and mapping technology, traditional surveying methods although there are great advantages in precision measurement. But it is not suitable for a wide range of global joint observation, GPS can complete a very good measurement of large area. GPS measurement technology to establish a global network of earth control, and can provide accurate coordinate system. GPS measurement technology plays a very important role in modern surveying and mapping technology.
This paper is mainly to discuss the measurement of GPS and its quality. In GPS measurement, measurement is an integral part of, in order to ensure the GPS measurement error can timely be found and improve the efficiency of whole industry measurement and intact realize measurement of data quality checking is to achieve an important part of the positioning accuracy is required. The quality check of the results of the external observation data is mainly including the checking of the repeated observation edges, the checking of the synchronous observation ring and the ring inspection of the asynchronous observation ring. According to these aspects to check the reliability of GPS measurement results. After the inspection still does not meet the accuracy requirements of the baseline, after a deep discussion and analysis, it is necessary to carry out the field of rework measurement. Up to the requirements of the measurement results.
