摘要
随着GPS技术的发展,在城市和区域地形测量中,GPS技术早已成为建立平面控制网的一种标准测量方式。不仅是高等级的首级网和加密网,甚至图根点和航空摄影测量像控点的测定都采用了GPS技术,使得控制测量的精度、效率都大为提高,然而碎部测量还是采用全站仪进行。本文阐述了用GPS RTK技术结合全站仪进行地形测量的方法,即在GPS信号良好时采用RTT定位技术,在RTK接收条件较差时,需要全站仪配合进行地形图的测绘。
关键词:GPS RTK 误差精度地形
Abstract
GPS(RTK) is a GPS measurement technology in the development of a new breakthrough, are now able to reach centimeter accuracy, has e the rapid acquisition of data and navigation tool. Its high efficiency, high precision and all-weather operation characteristics has been overwhelming majority of Surveying and mapping personnel and relevant departments of the wide application of. This paper mainly introduces the GPS (RTK) using the basic principle, position, application scope, technical characteristics, sources of error, the GPS (RTK) main development direction. This article on the RTK operating principle, basic configuration and location process in detail, and briefly introduces the GPSRTK technology application in topographic survey shows that GPS (RTK) the main advantages and disadvantages of GPS (RTK), error analysis, understanding of this stage GPS (RTK) can achieve the measurement precision. By this stage GPS ( RTK ) is the main direction of development, the main error sources in the process of using, and eliminate the use of error method, aware of GPS (RTK) in current measurement its application scope, through the exploration of stage GPS (RTK), the main development direction of GPS (RTK) of the main the error sources and the methods for eliminating the error of measurement, broaden the GPS (RTK) in subsequent measurement application scope, for future work laid the foundation for the measurement of.
Key word: GPS(RTK); Development direction; Sources of error; Error correction; Scope of application
