 针对GPS载波相位观测值中出现的周跳,首先分别对GPS相位观测值做单差和双差处理,再根据小波变换检测信号的奇异性原理,将GPS相位观测值发生周跳处视为信号的奇异点,通过MATLAB编程,分别对相位单差和双差观测值进行小波变换来探测周跳。实验证明,基于差分法的小波变换周跳探测效率比较高,周跳位置探测比较准,而且双差观测值的周跳探测比单差观测值效果好。 更多还原

【Abstract】 According to the cycle-slip of GPS carrier phase observation,in the paper the author firstly makes a single-difference and a double-difference respectively to GPS carrier phase observable,and the location of the cycle-slip is regarded as the bizarre point of the signal according to the principle of signal oddity detection,and secondly the wavelet transformation is used to detect the cycle-slip of the GPS carrier phase measurements to the single-difference and double-difference phases individuall...
