【摘要】：北斗衛(wèi)星導(dǎo)航系統(tǒng)是我國正在獨立自主建設(shè)和運行的衛(wèi)星導(dǎo)航系統(tǒng),經(jīng)過十幾年的建設(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,所以對該系統(tǒng)的服務(wù)能力進(jìn)行科學(xué)準(zhǔn)確的初始評估具有非常重大的意義。 本文以對北斗衛(wèi)星導(dǎo)航系統(tǒng)的原始觀測數(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)上實現(xiàn)了針對該系統(tǒng)原始觀測數(shù)據(jù)的有效測試和評估。本文主要對以下幾個方面進(jìn)行了探討和研究： (1)對北斗衛(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；簡單闡述接收機原始觀測值生成原理； (2)對影響北斗衛(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；對數(shù)據(jù)處理中涉及到的原始觀測值的線性組合及線性組合不同的特點進(jìn)行了詳細(xì)的討論分析； (3)對原始觀測數(shù)據(jù)的分析與處理中使用的方法進(jìn)行了研究討論,利用計算機編程語言對相應(yīng)的數(shù)據(jù)處理算法給予實現(xiàn),自主設(shè)計編制了數(shù)據(jù)處理與評估軟件,實現(xiàn)數(shù)據(jù)的自動處理和分析,滿足了實際處理要求； (4)對采集的原始觀測數(shù)據(jù)利用自編軟件進(jìn)行處理,并對獲得的解算結(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,能夠滿足實際的各種應(yīng)用和需求,評估算法和軟件有效可用,滿足對數(shù)據(jù)分析的要求。 通過本文以上的分析,可以看到北斗衛(wèi)星導(dǎo)航系統(tǒng)是一個可靠、高效衛(wèi)星導(dǎo)航系統(tǒng),能夠滿足實際應(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)實生活中應(yīng)用會越來越廣泛。
[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.
