Application of Inter-Satellite Links in Space Situation Awareness

Following analysis of the development and status quo of Inter-Satellite Links （ISL） and Space Situation Awareness （SSA） systems in China and other countries, this paper points out that ISLs play an important role in effective acquisition, secure transmission and real time application of spatial information and in improving the battlefield survivability of SSA systems. An SSA architecture encompassing a space communication model and a space navigation model is presented to meet demands for application of ISL links in future SSA systems. Design requirements and features of ISL links under the architecture are summarized. ISL links should have a flexible inter-satellite routing strategy and networking structure and they should support variable high data rate and secure and reliable inter-satellite data transmission. Key technologies for system implementation are presented from perspectives of space networks and satellite nodes and key areas and research methods for the key technologies are described. Results of the study provide reference and assistance to research and development efforts in ISL links and related fields.
