说明：  利用TOA与最小二乘法直接求解（具有独立创新性），TDOA是利用拉格朗日法求解，而且里面的定位图解做得特别好，分别有一点定位，多点定位的的三维视觉图。(TOA is directly solved by least squares method(Innovativeness),TDOA is solved by Lagrange's method.)

基于交流电机动态方程，编写Matlab分析程序，用于交流电机动态分析。(Based on the dynamic equation of AC motor, Matlab analysis program is written for dynamic analysis of AC motor.)

质心定位算法实现精度要求低的简单定位，加权质心定位比质心定位定位精度更高一些。(Centroid localization algorithm achieves simple positioning with low accuracy requirement, and weighted centroid localization is more accurate than centroid localization.)

说明：  卫星姿态是指卫星星体在轨道上运行所处的空间指向状态。将直角坐标系的原点置于星体上，指向地面的Z轴反映偏航方向，Y轴反映俯仰方向，X轴反映滚动方向。星体在高空中沿局部地球铅垂方向和轨道矢量方向运行，不时地产生对三轴的偏移。姿态控制是通过姿态控制分系统（ACS）来实现，使用地平扫描仪可感应俯仰和滚动轴的姿态误差，使用速度陀螺仪和罗盘可感应偏航轴的姿态误差。(Satellite attitude refers to the spatial orientation of a satellite in orbit. The origin of the Cartesian coordinate system is placed on the star, the Z axis pointing to the ground reflects the yaw direction, the Y axis reflects the pitching direction, and the X axis reflects the rolling direction. The stars move along the direction of the earth's vertical direction and the orbit vector in the high altitude, resulting in the deviation of the three axis from time to time. Attitude control is realized by attitude control subsystem (ACS). The attitude error of pitch and rolling axis can be induced by using horizon scanner, and the attitude error of yaw axis can be induced by using speed gyroscope and compass.)
