Software design for OBDH simulator of spacecraft based on data packet

With the rapid development of space technology,using spacecraft OBDH simulator which simulates On Board Data Handling subsystem to test the design of spacecraft has become a trend.In order to make the software of OBDH simulator to adapt the new changes of the OBDH subsystem and reduce the difficulty of software,be suitable for demand of user and existing hardware platform,a software design has been proposed in this paper.The design uses a layered system of data processing protocols to reduce the software complexity,uses data packets to process data and completes the data transmission based on data frames.The simulator has completed a 100 hours sophisticated test.The result indicates that this design is reliable,stable,and it also can meet the design requirements.
