Integrated Payload OBDH Technology for Deep Space Exploration

Deep space explorations put forward higher requirements on miniaturization and autonomy to probe's payload On-board Data Handling (OBDH) system. The novel highly integrated payload OBDH architecture is constructed by integrating payload electronics units and traditional payload OBDH units. This architecture can realize intensive use of resources, improve information unification and implement onboard autonomy conveniently. Payload OBDH architectures of the Chang'E series probes are introduced. Two novel integrated payload OBDH architectures are proposed, the low-cost scheme has been applied to China's first Mars exploration. Payload OBDH technical requirements for future deep space exploration are analyzed, and payload OBDH development trends are prospected.
