Abstract: The normal operation of the satellite requires the data transmission and management of inter-satellite network with reliability, timeliness, security, therefore transport tasks can be completed within the time prescribed. Hence an appropriate data transmission and management scheme should be designed to meet those requirements.1553B busbased data transmission has many advantages such as high transmission speed, good reliability and strong timeliness, thus 1553B bus is chosen as the data bus of the inter-satellite network. What’s more, a suitable data transmission and management scheme is proposed. This scheme reasonably designs the data structures, data types, network type, data transmission mechanism, data transmission process and data transmission time sequence. Finally, the data transmission and management scheme is tested on testing platform, test result shows that this scheme has high transmission speed, low error rate, good real-time performance and it meets the requirements.
