In the space-based multi domain information system, various electronic devices are increasing and bringing forth new ones, which makes the space-based multi domain information system have larger data volume, more data types and higher data complexity. The Data Distribution Service (DDS) technology is studied, and an implementation technology of data distribution service based on domestic operating system applied to the gateway of space-based multi domain information system is proposed; Based on the PowerPC P1022 platform, it completed the transplantation and adaptation in the localized autonomous and controllable embedded operating system which named FengYun YiHui(AIC-OS). Meanwhile, a space-based multi domain information distribution system based on DDS technology is built through combing the AIC-OS, VxWorks and Windows platforms. After that, according to the background demand of the integrated communication of the heaven and earth network, the connectivity, reliability, online sensing ability, communication delay and other capabilities of the system are tested. The experimental results show that the system can effectively realize the interconnection of space-based multi domain information systems, and realize the publication and subscription of data among different users.
