所有后档缝应当用双针链式缝迹或双行锁式线迹。
All back rise seams should be two-thread chain stitch or double row lock stitch.
再以该近似解和协方差矩阵为初值,由无迹卡尔曼滤波(ukf)实时估计双差整周模糊度的精确解。
Then the float ambiguity resolution was passed into an unscented Kalman filter as initial state value. UKF estimated the precise ambiguity resolution in real time with the initial value.
