Abstract With the continuous development of the deep space exploration technology and increase of the system complication, the design of software for the Attitude and Orbit Control System of deep-space-detector has become an important problem, the application of Real-Time Operating System in the astronavigation field is the current hot. According to the real-time、high、complication and high reliability of the Attitude and Orbit Control System of deep-space-probe, and Based on the theory of software architecture, this article makes the software designing for the Attitude and Orbit Control System of percussion-mission based on the flush bonding Real-Time Operating System—VxWorks. The integrated environment for software cross-development of VxWorks is used for simulating the designs. First, Analyzing the interdependence between each part of the Attitude and Orbit Control System of percussion-mission, this article designs the suitable hierarchical structure of the System’s software；This article designs the BSP for the CPU of 80x86 and generates the image file of VxWorks. This article also makes bootroom for the system ,and compiles drivers of equipages . Second, this article designs Time-processing and Interruption driven model based on the characteristics of Attitude and Orbit Control System of percussion- mission ； This article divides the Attitude and Orbit Control System appropriately and designs the module of schedule of several multi-tasks; This article designs the fault-tolerant property for the particle inversion；This article designs the module of System Memory management appropriately according to the characteristic of the systems. At last, this article designs the module of compiling code during the deep- space-detector working based on the flush bonding Real-Time Operating System—VxWorks.
