卡尔曼滤波器，敏感器组合形式为数字太阳敏感器+磁强计+速率陀螺，具体的参数物理含义请见文件中的注释，航天人依旧一目了然-Kalman filter sensor combinations for the digital sun sensor+ magnetometer+ rate gyroscope, specifically the physical meaning of parameters see comments in the file, astronauts still at a gl

This m file is used for designing the PD controller for space satellite, the Kalman filter is also used for filering the noise

this matlab file describe the sobel filter using matlab.
