英文摘要： Satellite navigation and communication systems is an important part of the buoy observations. The new theories, new methods and new technologies of the satellite navigation and communication used by the ocean buoy is the hot topics at the present. The performance of the major scientific issues are communication and navigation integration in one system ,safe and reliable signal transmission and ill-conditioned equation with a synchronous communication satellite positioning.The following three methods was proposed. The first method, deep integration of the communication signal and positioning signal is achieved by positioning stamp technology; The second method, the active avoidance and avoiding the passive anti-jamming is achieved by signal high bit rate and the technology of parasitic transmission; The last method, location of the ocean buoy obtained by single communication satellite is achieved by the establishment of single-satellite pseudorange / sea plane constraint / IMU dead-reckoning combination of measurement model machine and solution algorithm. The above three key technologies will make satellite navigation and communication system structure simple and reliable. These reseraches will create good conditions for the construction of China's ocean buoy satellite communications and navigation system and pr
