摘　　要：多项式拟合探测周跳受相位观测值所含误差的影响,随着采样数的增加,其探测周跳的能力随之降低,通常将观测数据分成若干段来进行处理。这样不可避免的增加工作强度,降低工作效率。本文根据多项式拟合探测周跳的基本原理,对多项式进行改进。经实验证明,利用改进后的多项式进行拟合能够有效地弥补传统方法的不足,使周跳的探测与修复更加稳定可靠。The algorithm of polynomial fitting to detect cycle slips is affected by the errors included in carrier phase observations, Which reducing the ability of cycle silp detection. At the same time, obsearvation data usually is divided into several pieces, Which will inevitably increase the working strength and decrease the efficiency. The authors have modified the polynomial fitting algorithm according to the basic principle. The test results show that the modified polynomial fitting algorithm can remedy the fault of traditional polynomial fitting and make cycle-slip processing more reliable.
