GPS signal simulation is based on the integration of information processing technology, communication theory and digital signal science and technology. It combines various success in the field of navigation and positioning with computer technology, and develops rapidly in the future. For example, GPS and other emerging and promising technologies play an increasingly important role in the information society, that is, the new technological revolution, and further promotes the development of human society And faster development, based on the theory of GPS, using MATLAB simulation platform to develop, research GPS signal simulator.
This paper briefly introduces the development of GPS, introduces the basic structure of GPS, introduces the relevant basic concepts and basic principles of GPS, namely, principle, composition and application, and introduces the composition of GPS signal in detail, and on the basis of transmission characteristics, studies and designs a GPS signal simulator based on MATLAB GPS signal simulator system for the platform, mainly including C / a code, D code generation and satellite positioning. Finally, this paper gives a brief introduction in detail and draws the conclusion of this design.
At present, the product I provide only has GPS function in China, so if your son is not using it in China, you don't need to buy it. However, if your son works in China, I would be happy to serve you. Please confirm if your son really needs this product.
I think our life will change greatly in the next few years. Our life should be more convenient, especially the current pension problem will be greatly alleviated. For example, robots will have to help the elderly who can't take care of, so that their quality of life will be improved a lot.
I believe that with the help of Internet cloud computing, it will be more convenient for people to travel. We don't need to buy a car, and it's more convenient to take a taxi Through GPS positioning system, taxi utilization rate is high, traffic is not congested, and people's life is more happy. I believe that the underground pipe network will be more perfect, and the phenomenon of flooding the streets will not occur because of the reduction of vehicles.
The application of environmental protection technology will also be greatly improved. The air quality should be very good, and the people's health level will also be greatly improved.
