Paper Abstract

One of the strategic goals for the development of space technology is to achieve the mass, volume and lifetime cost of spacecraft lower than at present, which requires lightweight, miniaturization, low power consumption, rapid design and rapid integration, rapid testing and other aspects to achieve a deep level of technical breakthroughs.[1] The traditional electronic system of satellite cabin is connected by cable, which has many disadvantages, such as large volume weight, narrow band, poor anti-electromagnetic interference ability, complex network connection and low integration. If the effective No-cable technology can be adopted, the dry weight of the space vehicle can be reduced, the utilization efficiency of the payload can be improved, and the layout of the internal conductor of the space vehicle can be reduced, which not only saves the space, but also shortens the development period. Therefore, the high-speed interconnection technology of electronic equipment in satellite cabin is studied in this paper. By analyzing the characteristics of information flow and sensor distribution in the satellite, laser communication technology is adopted for high speed interconnection. Aiming at the future application, the laser communication device in satellite cabin is designed and verified in orbit, which provides an effective support for the application of No-cable satellite.
