GPS测量 [论在铁路测量GPS-RTK技术的应用]
摘要:现代科技的引入，极大提高了铁路测量工作的效率和质量。尤其是GPS技术的在铁路测量工作的应用，铁路测量结果的准确性和精确度有了重大改善。在铁路线路初、定测阶段和施工阶段，利用GPS实时动态载波相位差分定位技术RTK来完成传统测量方法中的图根加密控制、像控点测定、带状图测绘以及施工放样测量等工作，并在统一坐标系下提供点位的三维数据信息，同时能实时提供经过可靠性检验的厘米级精度的测量成果，显著地提高了作业效率，因而在铁路工程中有着广阔的应用前景。

Abstract: the introduction of modern science and technology, which has greatly improve the efficiency of the railway measurement and quality. Especially the GPS technology in railway measurements, the application of measurement results and the accuracy of railway accuracy is a major improvement. The railway line, and set in early stage and the stage of construction, real-time dynamic using GPS carrier phase difference positioning technology RTK to complete the traditional measuring method of root encryption control, like figure control point determination, banded figure surveying and mapping and construction moulding survey, and in unity coordinates of 3 d data point to provide information, and at the same time can provide real-time inspection after reliability level of precision measurement results cm, improve the working efficiency,
