Research Of Satellite GPS Receiver Testing Simulation Environment And Check Assessment Software

As the increasing demands of satellite navigation serbices, a satellite navigation system developed by China independently is being constructed. As the Terminal of satellite navigation system, the Receivers’s test play an important role in Chinese space industry. Regarding the test platform’s characteristics and complexity, this thesis,in the light of the need of config the simulation environment of Receivers’s test, designed and implemented a set of automatic simulation environment config system for automatic receiver test, It contains three sections:Firstly, introduction the development of satellite navigation technology, and then introduction the significance of spaceborne GPS receiver related research. Elaborate the backround of designing and implementing a set of automatic simulation environment config system for automatic receiver test. Do research on GPS satellite navigation system theory. Lay the theoretical foundation for software production.In the second part, after evaluation of the satellite signal characteristic as well as the receiver’s working environment, analysis of the demand of the Sprient company’s software, SimGEN,to make the simulation. Based on the research of the key technology in the program production, and the research of GPS theory, follow the requirements of the technical, produced the SimGENconfig, design of targeted function, work with SimGEN to achieve the environment configuration for spaceborne satellite navigation testing.Finally, a concrete test is introduced. Design steps for test samples, the test platform’s working status and the auto data processing techniques are proposed. The test results show that SimGENconfig and SimGEN word together Can be conveniently flexibly create a set of simulation environment which can be used for satellite navigation satellite signal receiver testing. And meet the need of receiver test.
