The Research Of Test Methods And Tools Based On Beidou Ⅱ Satellite Navigation System

With the rapid development of China’s BeiDou Navigation and Positioning Systems (BDS), there areindustry attention for its hardware and software systems in the field of research Beidou navigation andpositioning system. The degree of attention in its hardware and software testing is increasing. In this paper,the technical requirements for the Beidou satellite navigation system II, summarizes the characteristics ofthe Beidou system testing project, combined BUG I tested in actual projects encountered, theestablishment of a test method for the Beidou satellite navigation system II and designed a high coverage,high efficiency test tools, which greatly improves the ability to test the efficiency of R&D and testersCompass and Compass user machine to determine the navigation software defects, provides an importantscientific basis for future testing. The details are as follows:(1) Through the Beidou satellite navigation system II hardware and software analysis, summed up thecomplexity of large systems, large data capacity, features a very complex interaction of hardware andsoftware more length and complexity of the internal structure of the program characteristics.(2) According to the analysis of the reasonableness of the Beidou Navigation Satellite System II hardwareperformance analysis and map geographic information data, developed a performance test and testsolutions map geographic information given test data generation methods.(3) the realization of this thesis satellite navigation system Beidou II testing tools, mainly divided intotwo parts: First, the Beidou satellite detection test, two is a map of the geographical test. Establish Beidousatellite navigation system testing tools II total design, analysis and design of major hardware architectureand software architecture.(4) Design Compass detection function modules. Beidou satellite data information through the usermachine port Compass received read and parse, analyze the performance of the Big Dipper to determinethe user machine chips and whether the user machine to complete the technical requirements of the index.(5) Compass map data test function module design, covering Regional compare features, comparefeatures road map, POI hotspot compare function, cross the intersection compare function.(6) proposed and designed navigation path planning algorithm comparison: Navigation path planningcan be divided into performance metrics to compare the effectiveness and rational judgments based.(7) Finally, under the technical guidance of the Beidou satellite navigation system II, designed to test software functionality and performance indicators to achieve conducted experiments and testing to meettest targets on maximizing the task is completed, verify the design and implementation of the systemsoftware correctness.By the design of the test methods and tools presented in this paper that has been achieved from theoverall test Beidou satellite navigation system II, found a bottleneck test, providing an important referencefor future testing in the field Beidou system.
