GPS控制测量在新农村建设中的应用研究

The Research on Application of GPS Control Survey in the Construction of the New Village

全球定位系统GPS是一种先进的测量工具,它的出现和不断发展,极大地促进了测绘工作的进步,具有快速、准确、高效的特点,而且不受地形条件的限制,大大提高了工程测绘的工作效率。本文结合南安市新农村D级GPS网的测量实例,阐述如何进行GPS控制网的技术设计、外业选点埋石、方案的观测实施、内业对观测数据的质量控制、基线解算、网平差计算以及精度分析等。同时对GPS平面控制网建立的有关问题提出一些建议。

The global positioning system GPS is an advanced measurement tool,and its emergence and development has greatly promoted the progress of the work of surveying and mapping.It is fast,accurate and efficient,and is not restricted to the topographical condition,greatly improving the working efficiency of engineering surveying and mapping.This paper describes how to plan the control network of GPS,choose the site and bury the stone outside,carry out the plan of measureing,control the observation data for the data processing,calculate baseline,and how to analyze the precision analysis with the measurment example of new country D-order GPS network in Nanan new village.At the same time,the paper puts forward some suggestions on the relevant problems of GPS plane control network establishment.
