Latest Patents
Zhaoxiang Wu holds a patent for a method titled "Method for correcting pointing errors of biaxial rotation system based on spherical cap function." This invention discloses a systematic approach to correcting pointing errors by utilizing a spherical cap function. The method involves several key steps, including error collection, error model fitting, and error control and compensation. The process begins with the selection of stars or radio sources for tracking and observation, which helps in obtaining both theoretical and measurement positions. The differences between these positions yield an error distribution. Subsequently, a suitable orthogonal spherical cap function is selected for fitting the error distribution, leading to the calculation of an error fitting coefficient. Finally, this model is integrated into a pointing control system for effective compensation. The method is noted for its strong stability and high correction accuracy, making it a valuable advancement in the field.
