[Abstract]:The establishment of Global Positioning system (GPS) provides time service for users. As an important part of the system, satellite navigation terminal equipment (hereinafter referred to as terminal) carries the important task of human-computer interaction. In order to evaluate and test the performance of the terminal, it is very necessary to develop a satellite terminal detection software. In this paper, the development of this software is studied and explored. This paper first summarizes the composition of the terminal detection software, the main functions of each part and the performance test items. Secondly, the basic knowledge of GPS satellite navigation system (GPS system) is systematically summarized, and the coordinate reference and navigation message of GPS system are expounded, and then the structure, classification, working principle and data interface of the terminal are analyzed. Finally, the establishment and evaluation algorithm of GPS user terminal detection system database are studied, and the database management and performance evaluation software of the detection system is developed. In this paper, the global positioning and navigation system is analyzed, and the importance of the terminal is described. The concepts and theories involved in the terminal are described, such as the principle of GPS navigation, the common coordinate system of GPS, the structure of GPS message and so on. Then the establishment of the database needed for the test of the terminal is discussed. The framework, content and E / R entity diagram of the database are described. Finally, the process of actual test and the algorithm of solving test data are discussed. This paper briefly expounds the concept of navigation system and terminal and the related theories involved. Based on the analysis of the information received by the terminal and the needs of the actual test, the establishment of the test database is studied. The contents of the database, the relationship between the table and the table, the test project and the relationship between the data are explained. Combined with the actual test requirements, some commonly used test items are described. The algorithm for solving the positioning accuracy test with high frequency is also explained.
