[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.
