EROS-1
On-Orbit Service Platform
Based on the rocket's final stage, the on-orbit service platform reuses the existing electrical, structural, and orbit-attitude control propulsion systems. It can be expanded into an upper-stage on-orbit test platform. Relying on the orbit-attitude control propulsion system, it possesses strong maneuvering and orbit-changing capabilities, enabling the on-orbit test and verification of new technologies.
