| Abstract: | The basic principle of the TTE/TTP technology is introduced, as the advantages such as time certainty, network conflict reducing compared with event triggered network are explored. The key technology including time scheduling table design, time synchronization and dynamic adjustment of the schedule is proposed towards the application of the TTE/TTP technology with the spacecraft. A feasible solution of the TTE/TTP technology with the spacecraft is clarified to meet the needs of high reliability, strong real time and time certainty of the future development of the spacecraft. |
