3、ch of AOS standard has become more and more important with the standard data of AOS adopted in international space technology step by step. As the basic instrument in transmitting AOS data is under slow construction, the

4、 further study about AOS is hindered seriously. Therefore, it is significant to develop AOS synchronous receiver for both the researches into the AOS standard and our country’s space technology. The paper achieves AOS Sy

5、nchronous Receiver, the basic instrument of AOS. Centered on CY7C68013A, the design makes it achievable for the receiver, through programming firmware of chip, to receive data, check the synchronization marker, protect t

6、he synchronous state and implement FIFO, which succeed in receiving data of AOS and passing it on to host by USB. Also, the functions of transmitter and receive are integrated to one card so that the system will keep on

7、 monitoring data from transmitter after loading firmware automatically. The results of subject are that the transceiver can receive the transmitted data intact by itself, that the system can realize consistence with the

8、PC plug-and-play architecture and that one transceiver can receive data from another at the rate of 20kbps with few errors. In conclusion, it is possible to adopt frame synchronization and synchronization protection in A

9、OS, and it is flexible to make use of USB interface in the communication between Receiver and PC. Now, AOS synchronization transceiver’s rate is not satisfying, but will make great progress by improving the design propos
