In order to offset the limitation of these traditional algorithms as Chan and Taylor, the location results of Chan are used as original value of Taylor Series Expansion algorithm, and the performance of location is improved effectively.

• 针对Chan算法和Taylor算法的优点和缺陷，提出了将Chan算法的定位结果作为Taylor算法的初始估计值代入，有效的提高了定位精度。
