摘　　要：针对GPS载波相位观测值的特点,提出了一种利用双差改正,用多项式拟合与最小二乘法相结合的方法探测与修复周跳。由于载波相位双差观测值不仅消除了卫星与接收机的钟差,而且大大的消弱了对流层电离层的影响,所以对于小到1周的小周跳很容易被探测出来,通过实验证明了该方法的可靠性和有效性。The author puts forward a method which combines polynomial fitting and least-square to detect and repair cycle-slip aiming at the characteristics of GPS carrier phase difference observation,because the double difference of carrier phase not only eliminate the clock errors of satellite and receiver,but also greatly lessen the impact of the ionosphere and troposphere,the cycle-slip such as less than one week easily be detected,this method has been proved reliability and validity by experiment.
