The micro-satellite formation and network is one of the focuses of the current space-based platforms research field. In this paper, the data transmission scheme for micro-satellite formation and network is achieved based on the next generation of tactical networking research. The overall scheme, research objectives, technical specifications and main contents are described, and the space borne terminal equipment is mainly introduced. Furthermore, the key technology and solution of the scheme is particularized. The data transmission scheme for formation and network is realized by distributed, no center and IP-based networks, enabling multiple platforms dynamic network, which has a high-speed, broad bandwidth, low time delay characteristics. And what＇ s more, the number of the network members can be more than 20 and data transmission network has high interference im- munity, anti-interception capability. The data transmission scheme for micro-satellite formation and network can achieve high transfer rates between micro-satellite platforms. As a result it has a good prospect in the space-based platform data link communication field.
