Abstract：Beidou satellite navigation system is a global satellite navigation system which is developed by China and being implemented now.With the U.S. GPS, Russian GLONASS , European Galileo satellite navigation system ,they were known as the world's top four . Beidou satellite navigation system is made by three parts, they are the end of space , the ground -side and client-side . It promotes the formation of satellite navigation industry chain and form a complete system for the support, promotion and protection of the national satellite navigation application industry , it also promotes a wide range of satellite navigation applications in various sectors of the national economy of society.
The design is based on STC89C51 singlechip to achieve a simple positioning and information display system of Beidou satellite. The functions of the control system is mainly to complete the data acceptation, time display, longitude display , latitude display and other routine functions. This scenario which is based on microcontroller, Compass 1602 LCD module and other hardware, applies the C language to extract the signals of Beidou satellite and display the signals .After practical tests, this receiver could receive and display information from Beidou satellite. it could also achieve the features of the small size, high accuracy, continuous navigation , and is widely used in personal outdoor adventure , taxi positioning and marine operations and so on.
Keywords: Beidou satellite navigation system, STC89C51, 1602 LCD module
