1、本科畢業(yè)設(shè)計(jì)(論文)題目GPSRTK用于圖根控制的研究44摘要GPSRTK(RealTimeKinematic)技術(shù)是指載波相位實(shí)時(shí)動(dòng)態(tài)差分GPS定位技術(shù),它量領(lǐng)域,是GPS發(fā)展的新形式,是GPS應(yīng)用的重大里程碑。它的出現(xiàn)為各種控制測(cè)量、地形測(cè)圖和工程放樣等帶來(lái)了曙光,極大地提高了測(cè)量工作的外業(yè)作業(yè)效率。為了擴(kuò)大GPSRTK技術(shù)在測(cè)量工作中的應(yīng)用范圍,滿足高精度的測(cè)量要求以及建立大面積的測(cè)量控制網(wǎng)的需要,擬通過(guò)具體的設(shè)計(jì)試驗(yàn)探尋出實(shí)用的測(cè)量方法來(lái)代替?zhèn)鹘y(tǒng)的常規(guī)測(cè)量方法,使測(cè)量工作更簡(jiǎn)便快捷。但是就目前來(lái)說(shuō),由于受衛(wèi)星信號(hào)、接收機(jī)狀態(tài)、測(cè)站周圍環(huán)境及儀器操作的影響,RTK定位有時(shí)會(huì)
2、出現(xiàn)失真,其成果不可能百分之百的可靠,為了將RTK更好地服務(wù)于測(cè)繪工程,有必要對(duì)RTK的測(cè)量精度進(jìn)行研究和分析。論文研究?jī)?nèi)容:⑴介紹GPSRTK的基本原理。⑵用RTK觀測(cè)的點(diǎn)位坐標(biāo)與靜態(tài)GPS觀測(cè)的成果進(jìn)行對(duì)比、檢測(cè)分析,從而來(lái)檢測(cè)RTK成果的質(zhì)量。⑶用RTK觀測(cè)的點(diǎn)位坐標(biāo)與全站儀觀測(cè)的導(dǎo)線點(diǎn)成果進(jìn)行對(duì)比、檢測(cè)分析,從而來(lái)檢測(cè)RTK成果的質(zhì)量。關(guān)鍵詞:GPSRTK;圖根控制;精度分析44AbstractThetechnologyofGPSRTK,namely,thetechnologyofthecarrierphasereal-timedynamicdifferentialpos
