摘　　要：在时差定位中Taylor级数展开法是否有效收敛受到初始位置选择的约束,比较三种初始位置选择方法:真实位置法,Chan算法以及渐近线交点法,通过试验说明三种方法在Taylor级数展开法定位中不同的性能。In time-of-arrival or not is restricted by initia ocation,that the Taylor series deployment method is contracted position selection. This paper compares three methods of the initial position selection, real position, Chan algorithm and the method of asymptote cross point,shows the different performance among the three methods in Taylor series deployment method through the test.

关 键 词：Taylor级数展开法 初始位置 双曲线 渐近线
