【摘要】：GPS(Global Positioning System)測(cè)量控制網(wǎng)平差是用來(lái)評(píng)定GPS網(wǎng)的內(nèi)符合精度,發(fā)現(xiàn)和剔除GPS基線向量觀測(cè)值中可能存在的粗差以及獲取網(wǎng)點(diǎn)坐標(biāo)的方法,在GPS測(cè)量數(shù)據(jù)處理中占據(jù)重要地位。本文結(jié)合石油物探測(cè)量的特點(diǎn),對(duì)GPS網(wǎng)平差的數(shù)據(jù)處理流程及算法進(jìn)行研究,并予以編程實(shí)現(xiàn),具有一定的實(shí)用價(jià)值。本文首先介紹了GPS測(cè)量數(shù)據(jù)處理常用的坐標(biāo)系統(tǒng)及坐標(biāo)轉(zhuǎn)換的基本原理;對(duì)GPS基線解算方法進(jìn)行了研究,包括:基于雙差相對(duì)定位的傳統(tǒng)基線解算方法和基于非差精密單點(diǎn)定位(precise point positioning,PPP)的基線解算方法;重點(diǎn)研究了GPS工程控制網(wǎng)平差的理論和相關(guān)算法,包括GPS網(wǎng)的三維無(wú)約束平差、三維約束平差、二維約束平差以及GPS高程擬合;利用MATLAB語(yǔ)言,本文實(shí)現(xiàn)了GPS工程控制網(wǎng)平差的基本算法,編制了相應(yīng)的程序;以CPI GPS控制網(wǎng)和吉蘭泰工區(qū)石油物探測(cè)量GPS控制網(wǎng)觀測(cè)數(shù)據(jù)為例,通過(guò)與COSAGPS軟件和TGO軟件處理結(jié)果的比較和分析,對(duì)自編GPS網(wǎng)平差程序進(jìn)行了算法驗(yàn)證。結(jié)果表明:1)自編GPS網(wǎng)平差程序三維無(wú)約束平差結(jié)果在三個(gè)坐標(biāo)分量上的最大誤差均在1.0cm以內(nèi),系統(tǒng)偏差優(yōu)于7mm,均方根誤差(RMS)優(yōu)于7mm;2)自編程序三維約束平差結(jié)果在三個(gè)坐標(biāo)分量上的最大誤差均在1.5cm以內(nèi),系統(tǒng)偏差優(yōu)于8mm,均方根誤差(RMS)優(yōu)于8.5mm;3)自編程序二維約束平差的平面坐標(biāo)結(jié)果的最大誤差在2.2cm以內(nèi),系統(tǒng)偏差為1cm左右,均方根誤差(RMS)為1cm左右;4)自編程序高程擬合結(jié)果的最大誤差在4.5cm以內(nèi),系統(tǒng)偏差為2cm左右,均方根誤差(RMS)為3cm左右。上述統(tǒng)計(jì)數(shù)據(jù)驗(yàn)證了自編GPS網(wǎng)平差程序算法的正確性和程序設(shè)計(jì)的合理性,與石油物探測(cè)量中廣泛采用的商用TGO軟件處理結(jié)果基本一致,可以滿足實(shí)際生產(chǎn)的需求。
[Abstract]:The adjustment of GPS (Global Positioning System) measurement control network is used to evaluate the inner coincidence accuracy of GPS net, to find and eliminate the possible gross errors in the GPS baseline vector observations and to obtain the dot coordinates, which plays an important role in the GPS measurement data processing. According to the characteristics of petroleum geophysical survey, this paper studies the data processing flow and algorithm of adjustment in GPS net, and realizes it by programming, which has certain practical value. In this paper, the coordinate system and the basic principle of coordinate transformation in GPS data processing are introduced, and the solution method of GPS baseline is studied. Including: the traditional baseline solution method based on double difference relative positioning and the baseline solution method based on non-differential precise point positioning (precise point positioning,PPP), the theory and related algorithms of GPS engineering control network adjustment are studied emphatically, including the three-dimensional unconstrained adjustment of GPS net. Three dimensional constraint adjustment, two dimensional constraint adjustment and GPS height fitting, using MATLAB language, the basic algorithm of GPS engineering control network adjustment is realized and the corresponding program is worked out. Taking the observation data of CPI GPS control network and GPS control network of petroleum geophysical survey in Jilantai area as an example, the adjustment program of GPS net is verified by comparing and analyzing the processing results with COSAGPS software and TGO software. The results show that the maximum error of the three dimensional unconstrained adjustment results in the three coordinate components of the GPS net adjustment program is within 1.0cm. The system deviation is better than 7mm, the root mean square error (RMS) is better than 7mm / 2) the maximum error in the three coordinate components is within 1.5cm. The system deviation is better than 8 mm, and the root mean square error (RMS) is better than 8.5 mm / 3) the maximum error of the plane coordinate results of 2-D constrained adjustment is within 2.2cm, and the system deviation is about 1cm. The root-mean-square error (RMS) is about 1cm (4) the maximum error of height fitting result is within 4.5cm, the system deviation is about 2cm, and the RMS error (RMS) is about 3cm. The above statistical data verify the correctness of the adjustment program algorithm and the reasonableness of the program design, which are basically consistent with the processing results of commercial TGO software widely used in petroleum geophysical survey, and can meet the needs of actual production.
