Abstract: In order to meet the requirements of refined modeling and fault simulation, function modules of swing infrared earth sensor (IRES) was identified according to its working principle, main fault modes of each module was analyzed, mathematical fault model based on physical mechanism was designed, and a program for normal and fault simulation was written. The refined fault model can calculate attitude angles exactly, reflect signal relationship between inside modules, and simulate various fault modes effectively. The model can be used in simulating, testing and fault diagnosis and so on.

Key words: infrared earth sensor, module identification, fault mode analysis, fault modeling, simulation
