摘  要

    本論文主要介紹GPS(RTK)的基本原理、系統(tǒng)組成、技術(shù)特點(diǎn)、誤差來(lái)源和使用方法及操作步驟，并利用GPS(RTK)在工程測(cè)量中進(jìn)行點(diǎn)放樣、曲線放樣以及在地籍測(cè)量中進(jìn)行界址點(diǎn)測(cè)量，對(duì)測(cè)量結(jié)果進(jìn)行精度分析。通過(guò)對(duì)放樣點(diǎn)和界址點(diǎn)測(cè)量結(jié)果的精度分析，得出了GPS(RTK)的測(cè)量精度是可以達(dá)到工程放樣和界址點(diǎn)測(cè)量的精度要求的結(jié)論，并且通過(guò)工程實(shí)例說(shuō)明了GPS(RTK)具有工作效率高、定位精度高、全天候作業(yè)、數(shù)據(jù)處理能力強(qiáng)和操作簡(jiǎn)單易于使用等特點(diǎn)。通過(guò)本文的論述我們了解了如何使用GPS(RTK)進(jìn)行工程放樣和界址點(diǎn)測(cè)量，并為GPS(RTK)在工程放樣和界址點(diǎn)測(cè)量的可行性進(jìn)行了論證，拓展了GPS(RTK)在測(cè)量領(lǐng)域的應(yīng)用范圍，增強(qiáng)了使用GPS(RTK)的實(shí)際操作能力，為以后承擔(dān)更多的測(cè)量工作奠定了基礎(chǔ)。

ABSTRACT

The present paper is mainly introduced GPS(RTK) the basic principle, the system composition, the technical characteristic, the error source and the application method and the sequence of operation, and carry on a lofting, the curve lofting as well as using GPS(RTK) in the project survey carry on the boundary point survey in the cadastration, carries on the precision analysis to the measurement result. Through to the lofting and the boundary point precision analysis, has obtained the GPS(RTK) measuring accuracy is may achieve the project lofting and the boundary point survey precision request conclusion, and explained through the project example GPS(RTK) has the working efficiency high, the pointing accuracy high, the all-weather work, data-handling capacity strong and the operation simple easy to use and so on the characteristics. Elaborated us through this article to understand how used GPS(RTK) to carry on the project lofting and the boundary point survey, and was GPS(RTK) has carried on the proof in the project lofting and the boundary point survey feasibility, has developed GPS(RTK) in the survey domain application scope, strengthened has used GPS(RTK) the actual operation ability, will undertake the more surveying work for later to lay the foundation.

Key words：GPS(RTK)；Project lofting； Lofting；Curve lofting；Cadastration； Boundary point
