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

数字滤波器，用于数据预处理，虑掉不需要的频率成分-A time domain modal parameter identification, can be measured data get the structure frequency and damping ratio and mode shapes
