Design And Implementation Of Satellite Signal Simulator Control System

The factors that include development of economy, improvement of science andtechnology, national satellite launch, the satellite field in the growing demand and so on,have led to the rapid development of the satellite.At the same time, satellite technologyhas been played a key role in the national informatization construction.As an importantpart of the satellite technology,the satellite signal simulation technology is also veryimportant.The satellite signal simulation technology starts late in China, technology isrelatively backward, and relates to the sensitive technology, core technology abroad,which strictly confidential,all these factors lead to slow development in this field in China,and there are still some gaps in foreign countries.In this background, research andimplementation of a satellite signal simulator platform is very important, and has becomean important issue that has a great influence on the future of the information construction.Firstly,we introduce research background and international research profile in thefield of satellite signal simulator, which fully illustrates the great significance of thedesign and development platform for satellite signal simulator significance.Then weresearch the related technology to the satellite signal simulator control system,incluededby involving serial communication, multi-threading, data analysis, graphics and other keytechnologies.Based on the demand,designing a system architecture, network architecture,module interfaces and system protocol, finishing the system algorithm program andinterface program by using C++language, and ultimately complete the design andimplementation of the system and testing.In the project design and implementationprocess,we creative use of a lot of good design and implementation, including the multifunction integrated, open system architecture, the satellite signal resolution scheme, datachart display scheme, simulator control management, log management scheme.The corevalue of the satellite signal simulator control system is in-depth understanding andsimplifies the satellite signal analysis control process, great to meet the actual needs.In the system design and implementation process,we meet the functionalrequirements as the foundation, focuse on ease of use, scalability and security.The systemcan satisfy the actual demand function well, control convenient, intuitive display correctly, modular low coupling, and improves the log management and safety control system.Thesystem has been put into practice, mainly used in the research and development ofnavigation receiver, theoretical research, teaching, receiver or an OEM board performancetest and evaluation, laboratory construction and other aspects.The system is developed tooptimize the work flow, improve work efficiency, bring bigger economic benefits, a hugeexpansion space and good popularization value.
