Navigation and control software design and implementation for lunar rover validating system

This paper provides the design and implementation of navigation and control software for an aerospace-level lunar rover validation system. Based on analysing structure characteristics of the navigation and control system, real-time navigation and control software involving interrupt service routine, tasks, and task-task communication is designed and implemented within the embedded operation system VxWorks. Although the current research of our project is still on the way, this navigation and control software designed here is already successfully applied in some of physical experiments on the lunar rover platform. The practical employment indicates the utility and reliability of the designed software totally satisfying design requirements of the navigation and control system.
