Based on the traditional Momentum-Blade Element theory, an improved method of aerodynamic calculation about the horizontal axis wind turbine in yaw or in pitch-up is presented in this paper.

Attitude control problem of a three-axis stabilized, momentum biased, and nadir-pointing satellite is investigated based on yaw observer.

This paper studied the extraction of the pitch and yaw angular errors of the line-of-sight to seeker-axis under the function of MMW step frequency target identification.
