Abstract: The research of spacecraft attitude measurement based on three-dimensional spatial structure vectors of electromagnetic wave can make up for the lack of space reference and enrich the attitude measurement tools of space vehicles. Based on the variational pattern between sense attitude and positions of defect electromagnetic vector sensors, the signal steering vector of polarizing array borne on a spacecraft is set up. The platform attitude measurement is realized according to the maximization of multiple signal spatial sum-spectrums of cooperative navigation. The multi-position sensors measurement can avoid occlusion, achieve higher attitude accuracy, and expand the application field of the system. In the state of receiving the full electromagnetic information, the stationary clutter can be used as the attitude reference without the navigation signal. The simulation results verify the effectiveness of the attitude estimation.

Key words: electromagnetic vector sensor, state of polarization, steering vector, attitude/heading, spatial spectrum
