The Design And Implementation Of The Satellite Navigation Terminal Detection Software

The establishment of the global positioning satellite system to provide users withlocation-based services of the timing.(Hereinafter referred to as an important part of thesystem, satellite navigation terminal device terminals) carries the important task ofhuman-computer interaction. In order to be able to performance evaluation and testing ofthe terminal, the development of a satellite terminal detection software is very necessary.In this paper, the development of this software, research and exploration.Firstly, an overview of the composition of the terminal detection software, the mainfunction of each part, and performance testing of the project; followed systematicallysummarize the basics of GPS satellite navigation system (GPS system), elaborated GPSCoordinate reference and navigationmessage content; then analyzed the structure of theterminal, classification, working principle and data interface; Finally, the establishment ofthe database of the the GPS user terminal detection system as well as assessmentalgorithm based on research, and the development of database management andperformance evaluation of the detection systemsoftware.This paper analyzes the global positioning satellite navigation system, theimportance of the terminal. Terminal concepts and theories related to the elaborate, such as:GPS navigation principles, GPS common coordinate system, GPS message structure. Thendiscussed the establishment of the terminal test database. The framework of the database,the content, and E-R entity diagram has been described. Finally, the actual process oftesting and test data solver algorithm discussed.This article is intended as a general elaborated the concept, as well as related to thetheory of the navigation system and terminal. Exploratory studies carried out to establishthe database of test data on the basis of the analysis of the information received on theterminal, combined with the actual test. The contents of the database, the contact betweenthe contact between the table and the table, the test project, data are described. The actualtest requirements, test methods on the part of the commonly used test project. And using ahigher frequency of the positioning accuracy of test solution algorithm has been described.
