In this paper, the integration among on-board computer-MPC555, power supply unit, and ground station is presented. The design is to execute the mission performance under the satellite orbiting mode, includes supervising and managing satellite operation, handling and archiving information and message, receiving and executing the ground station command and the satellite bursting incident. Where the multi-task and real-time functions of an embedded system are accomplished, then the satellite flight software is established. The flight software includes initialization and autonomous operation of onboard computer which performs several tasks of satellite operation to meet mission requirement. Under operation mode, these tasks are capable of monitoring satellite's health data, power supply unit, GPS status and handling incident events.
