1、本科畢業(yè)設(shè)計(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)時動態(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)為各種控制測量、地形測圖和工程放樣等帶來了曙光,極大地提高了測量工作的外業(yè)作業(yè)效率。為了擴(kuò)大GPSRTK技術(shù)在測量工作中的應(yīng)用范圍,滿足高精度的測量要求以及建立大面積的測量控制網(wǎng)的需要,擬通過具體的設(shè)計試驗(yàn)探尋出實(shí)用的測量方法來代替?zhèn)鹘y(tǒng)的常規(guī)測量方法,使測量工作更簡便快捷。但是就目前來說,由于受衛(wèi)星信號、接收機(jī)狀態(tài)、測站周圍環(huán)境及儀器操作的影響,RTK定位有時會
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)于測繪工程,有必要對RTK的測量精度進(jìn)行研究和分析。論文研究內(nèi)容:⑴介紹GPSRTK的基本原理。⑵用RTK觀測的點(diǎn)位坐標(biāo)與靜態(tài)GPS觀測的成果進(jìn)行對比、檢測分析,從而來檢測RTK成果的質(zhì)量。⑶用RTK觀測的點(diǎn)位坐標(biāo)與全站儀觀測的導(dǎo)線點(diǎn)成果進(jìn)行對比、檢測分析,從而來檢測RTK成果的質(zhì)量。關(guān)鍵詞:GPSRTK;圖根控制;精度分析44AbstractThetechnologyofGPSRTK,namely,thetechnologyofthecarrierphasereal-timedynamicdifferentialpos
