A high reliable satellite communication for emergency communications

In this paper, a novel high reliable satellite communication architecture is presented for emergency communication, which is based on the telecommand, telemetry and control (TT&C) system. The TT&C system is capable to provide high reliable communication among the different TT&C ground stations. In the meantime, there are lots of ground stations located in different areas in China. And many of these areas belong to earthquake-prone zone. It makes sense by using such resources in the emergency especially when other communication manners no longer work. Moreover, in this new architecture, no specific satellite systemic level revision is necessary such that the current satellite in orbit can be utilized. The revisions are only focused on the telecommand, telemetry and control ground station. As a result, it is easily to be implemented comparing with other emergency communication scheme.
