The Technology of Bus Network Communication for Space Environment

The space battlefield environment is becoming increasingly complex. Multiple aircrafts often attack the same or different targets in cooperation when performing missions. The information of network interaction between aircrafts will determine the attack power of the whole system. In this paper, the SpaceWire bus with high bandwidth, high reliability, strong openness, good real-time and strong certainty is used as the inter vehicle bus, and a distributed inter aircraft bus network architecture is proposed. Through the modeling and Simulation, this paper analyzes the constraint parameters of bus network transmission under different conditions. It verifies the rationality and reliability of the design, and provides some reference for the practical application of bus network communication between aircrafts.
