Abstract


Embedded systems are widely used in the production process control , data acquisition , aerospace and other occasions , the common feature of these applications is to require the system to be able to respond quickly to events , and therefore have a strong real-time requirements of embedded operating system . μC/OS- Ⅱ real-time operating system is a hard real-time systems , time can be deterministic , with a clear real-time constraints . μC/OS- Ⅱ the United States Federal Aviation Administration RTCADO178B of standard certification in 2000 , and has sufficient stability and security . \Binary positioning in a communication system receiver is positioning communication terminal, it is reasonable design can improve the effectiveness of the use of the entire communication system efficiency and communication , the development of the system has an important significance . ΜC/OS- Ⅱ real - time operating system for satellite navigation receiver, to ensure the security of the receiver , to provide real time and other aspects of the task processing has a significant effect for improving the stability of the receiver . This article describes the Beidou navigation system , including system performance , composition , functions and system works ; build a the Beidou navigation receiver hardware platform , the overall design of the receiver , the focus of the baseband signal processing ; detailed study μC/OS- Ⅱ real-time operating system , and the μC/OS- Ⅱ ported to the embedded processor NIOS Ⅱ build out the system software platform ; according to the requirements of the receiver , the system is divided into a hardware circuit layer , the task focus on the task layer of the layer and the layer of the operating system , carried out a detailed study and design ; summary of the the Beidou navigation receiver based on the real-time operating system μC/OS- Ⅱ design features , the system improved . In this paper, the successful development of the Beidou navigation receiver based on the real-time operating system μC/OS- Ⅱ , focus on the receiver of μC/OS- Ⅱ build a complete system of hardware and software platforms . The subject of research to the field of applied research in the embedded operating system with high theoretical and practical value for the development of the Beidou receiver can inspire .
