An improved positioning method of piecewise code smoothing is introduced, which freezes the weighting factor in the process of computation to keep the weight of current observations.

提出了改进的相位平滑伪距定位方法，整个平滑过程是分段进行的，而且当平滑进行到一定程度时，将加权因子冻结，以保持当前观测值的权重。

Besides weighting, another factor that impacts long-term analysis is the emergence of new products and services.
