一种基于多项式拟合法的新的单频周跳探测方法

A new method for cycle-slip determination in single-frequency phase observation based on polynomial fitting method

多项式拟合法由于其算法简单,适合于计算机运算而在周跳探测中被广泛采用。但其探测周跳的能力受载波相位观测值的观测误差和采样率的较大限制,探测小周跳的能力比较弱,常常结合其它方法进行。本文提出了一种结合广义延拓插值法和多项式拟合法进行周跳探测的新方法,介绍了其数学原理和模型,并给出了具体实施步骤,最后用算例验证了方法的可靠性和有效性。

The algorithm of polynomial fitting to detect cycle slips is widely used because of its simple algorithm and easily programming.But its ability of detecting cycle slips is restricted by the observation error and sampling rate and its ability on detecting small cycle slip is weak.So,it often combined with other methods for detecting.This paper puts forward a new method which combines with Generalized Extended Interpolation Method and Algorithm of polynomial fitting to detect cycle slips.This paper also introduces its mathematical theory and model,and gives the specific implementation steps.Finally results of a test show that this new method makes cycle-slip processing more reliable and effective.
