【摘要】：CORS-RTK是整個(gè)CORS系統(tǒng)中最重要的應(yīng)用,是集計(jì)算機(jī)技術(shù)、網(wǎng)絡(luò)技術(shù)、通訊技術(shù)、衛(wèi)星定位技術(shù)于一體的實(shí)時(shí)差分定位技術(shù)。同傳統(tǒng)RTK相比,它具有更高的定位精度、更遠(yuǎn)的作業(yè)范圍、更高的可靠性以及更高的作業(yè)效率。該技術(shù)已經(jīng)廣泛應(yīng)用于眾多領(lǐng)域了。 目前,雖然多基站CORS系統(tǒng)是國內(nèi)外學(xué)者的研究熱點(diǎn),但其高昂的建設(shè)成本讓一些小規(guī)模的單位望而卻步,而單基站CORS系統(tǒng)因其建設(shè)成本低、施工周期短、技術(shù)成熟、拓展方便等優(yōu)勢彌補(bǔ)了這一點(diǎn),讓其在中小城市和地區(qū)有了一定應(yīng)用市場。 本文基于大連理工大學(xué)單基站CORS系統(tǒng)項(xiàng)目(LGCORS)展開研究,參與了整個(gè)系統(tǒng)的規(guī)劃組建和性能測試,并最終歸納總結(jié)出一套適合單基站CORS系統(tǒng)建設(shè)和測試的方法。論文的主要研究成果如下： (1)學(xué)習(xí)國內(nèi)外學(xué)者研究成果,總結(jié)了網(wǎng)絡(luò)RTK基本原理與誤差來源,介紹了當(dāng)前流行的幾種網(wǎng)絡(luò)RTK的技術(shù),為LGCORS系統(tǒng)的建設(shè)與測試奠定理論基礎(chǔ)。 (2)詳細(xì)介紹了LGCORS系統(tǒng)的基準(zhǔn)站、通訊網(wǎng)絡(luò)、數(shù)據(jù)中心的建設(shè)過程,總結(jié)一套單基站CORS系統(tǒng)建設(shè)方案。 (3)通過對網(wǎng)絡(luò)RTK測試內(nèi)容的研究分析,歸納出適合單基站CORS-RTK的測試方法和實(shí)施方案。 (4)結(jié)合大連市連續(xù)運(yùn)行衛(wèi)星定位服務(wù)系統(tǒng)(DLCORS)和部分大連市B級(jí)GPS點(diǎn),完成了LGCORS系統(tǒng)內(nèi)符合精度、外符合精度、時(shí)間可用性、空間可用性、差分定位均勻性、定位服務(wù)時(shí)效性及接收機(jī)兼容性的內(nèi)容測試和評(píng)價(jià)分析。
[Abstract]:CORS-RTK is the most important application in the whole CORS system. It is a real-time differential positioning technology which integrates computer technology, network technology, communication technology and satellite positioning technology. Compared with traditional RTK, it has higher positioning accuracy, longer range of work, higher reliability and higher efficiency. This technology has been widely used in many fields. At present, although the multi-base station CORS system is the research hotspot of domestic and foreign scholars, but its high construction cost makes some small units prohibitive, while the single base station CORS system has low construction cost, short construction period and mature technology. Expansion and other advantages make up for this point, so that small and medium-sized cities and regions have a certain application market. Based on the research of (LGCORS), a single base station CORS system project of Dalian University of Technology, this paper takes part in the whole system planning and performance testing, and finally summarizes a set of methods suitable for the construction and testing of single base station CORS system. The main research results are as follows: (1) studying the research results of scholars at home and abroad, summarizing the basic principles and error sources of network RTK, introducing several popular technologies of network RTK. It lays a theoretical foundation for the construction and testing of LGCORS system. (2) the construction process of reference station, communication network and data center of LGCORS system is introduced in detail, and a set of construction scheme of CORS system for single base station is summarized. (3) through the research and analysis of network RTK test content, the test method and implementation scheme suitable for single base station CORS-RTK are concluded. (4) combined with Dalian continuous operation satellite positioning service system (DLCORS) and part of Dalian B-class GPS point, the accuracy of LGCORS system is completed, including the accuracy of coincidence, the accuracy of external coincidence, the availability of time, the availability of space and the uniformity of differential positioning. Content testing and evaluation of timeliness and receiver compatibility.
