【摘要】：北斗衛(wèi)星導(dǎo)航系統(tǒng)是我國(guó)正在獨(dú)立自主建設(shè)和運(yùn)行的衛(wèi)星導(dǎo)航系統(tǒng),經(jīng)過(guò)十幾年的建設(shè)到目前為止已經(jīng)可以為亞太地區(qū)提供導(dǎo)航服務(wù),為促進(jìn)該系統(tǒng)健康有序的發(fā)展,所以對(duì)該系統(tǒng)的服務(wù)能力進(jìn)行科學(xué)準(zhǔn)確的初始評(píng)估具有非常重大的意義。 本文以對(duì)北斗衛(wèi)星導(dǎo)航系統(tǒng)的原始觀測(cè)數(shù)據(jù)分析為目標(biāo),系統(tǒng)的研究該衛(wèi)星導(dǎo)航系統(tǒng)的基本理論、模型、方法。在此基礎(chǔ)上實(shí)現(xiàn)了針對(duì)該系統(tǒng)原始觀測(cè)數(shù)據(jù)的有效測(cè)試和評(píng)估。本文主要對(duì)以下幾個(gè)方面進(jìn)行了探討和研究： (1)對(duì)北斗衛(wèi)星導(dǎo)航系統(tǒng)的現(xiàn)狀、系統(tǒng)組成、工作原理等進(jìn)行了總結(jié)介紹；簡(jiǎn)單闡述接收機(jī)原始觀測(cè)值生成原理； (2)對(duì)影響北斗衛(wèi)星導(dǎo)航系統(tǒng)的誤差模型進(jìn)行了介紹分析,并給出了部分誤差的數(shù)學(xué)影響模型；對(duì)數(shù)據(jù)處理中涉及到的原始觀測(cè)值的線性組合及線性組合不同的特點(diǎn)進(jìn)行了詳細(xì)的討論分析； (3)對(duì)原始觀測(cè)數(shù)據(jù)的分析與處理中使用的方法進(jìn)行了研究討論,利用計(jì)算機(jī)編程語(yǔ)言對(duì)相應(yīng)的數(shù)據(jù)處理算法給予實(shí)現(xiàn),自主設(shè)計(jì)編制了數(shù)據(jù)處理與評(píng)估軟件,實(shí)現(xiàn)數(shù)據(jù)的自動(dòng)處理和分析,滿足了實(shí)際處理要求； (4)對(duì)采集的原始觀測(cè)數(shù)據(jù)利用自編軟件進(jìn)行處理,并對(duì)獲得的解算結(jié)果進(jìn)行分析,表明北斗衛(wèi)星導(dǎo)航數(shù)據(jù)質(zhì)量較好,能夠滿足實(shí)際的各種應(yīng)用和需求,評(píng)估算法和軟件有效可用,滿足對(duì)數(shù)據(jù)分析的要求。 通過(guò)本文以上的分析,可以看到北斗衛(wèi)星導(dǎo)航系統(tǒng)是一個(gè)可靠、高效衛(wèi)星導(dǎo)航系統(tǒng),能夠滿足實(shí)際應(yīng)用的各種需要。相信隨著北斗衛(wèi)星導(dǎo)航系統(tǒng)不斷的建設(shè)和完善,該系統(tǒng)在現(xiàn)實(shí)生活中應(yīng)用會(huì)越來(lái)越廣泛。
[Abstract]:The Beidou satellite navigation system is a satellite navigation system that is being independently built and operated in China. After more than a decade of construction, it has been able to provide navigation services for the Asia-Pacific region so as to promote the healthy and orderly development of the system. Therefore, it is of great significance to evaluate the service capability of the system scientifically and accurately. In this paper, the basic theory, model and method of Beidou satellite navigation system are studied systematically with the aim of analyzing the original observation data of Beidou satellite navigation system. On this basis, the effective test and evaluation of the original observation data of the system are realized. This paper mainly discusses and studies the following aspects: 1) the present situation, system composition and working principle of Beidou satellite navigation system are summarized and introduced, and the principle of generating the original observation value of the receiver is briefly described. 2) the error model affecting Beidou satellite navigation system is introduced and analyzed, and the mathematical influence model of partial error is given. The characteristics of linear combination and linear combination of the original observations involved in data processing are discussed and analyzed in detail. 3) the methods used in the analysis and processing of the original observation data are studied and discussed. The corresponding data processing algorithms are realized by computer programming language, and the data processing and evaluation software is designed and compiled independently. Realize the automatic processing and analysis of the data, meet the actual processing requirements; (4) the original observation data collected are processed by using self-compiled software, and the calculated results are analyzed. The results show that the Beidou satellite navigation data is of good quality and can meet various practical applications and needs. Evaluation algorithms and software are available to meet the requirements of data analysis. Through the above analysis, we can see that Beidou satellite navigation system is a reliable and efficient satellite navigation system, which can meet the needs of practical applications. It is believed that with the continuous construction and improvement of Beidou satellite navigation system, the system will be used more and more widely in real life.
