| Abstract: |
| There are 24 MEO（Medium Earth Orbit） satellites in the Beidou-3 satellite navigation system. In order to quickly complete the construction process，a dedicated platform was designed for Beidou satellites. The dedicated satellite platform was suitable for one mission to launch multiple satellites directly into orbit. In this paper, we also studied the key subsystems of the platform. The research shows that the dedicated satellite platform features high integration, strong carrying efficiency, high power-to-mass ratio, and good satellite layout. |
