Modeling and Simulation of Integrated Attitude Determination with Star Sensors and Infrared Horizon Sensors

According to the measuring model of star sensors and infrared horizon sensors and the attitude determination estimation model applying memory-attenuating least squares filtering,the simulation was made based on the RT-LAB real-time simulation platform and the MATLAB/Simulink digital simulation platform in this paper.The results showed that the precision of attitude determination for the combination of star sensors and infrared horizon sensors was high,and the simulation based on real-time RT-LAB platform was convenient,efficient,accurate and open to be accomplished.
