GPS Signal Noise Characteristics Based on Wavelet Analysis

LI Haiwen,JIANG Siyi,LI Xiangmin,ZHOU Haifeng,ZENG Kaining (Department of Civil Engineering,Guangxi Polytechnic of Construction,Nanning 530003,China)  
The author extracted the original carrier signal of Nanning experimental GPS control network observation data,using the advantage of wavelet analysis theory in analysis separately such as multi-scale,multi-resolution,scalable and shiftable,decomposed original carrier signal extracted,single-difference observations and the double difference observations with db3 wavelet function for 3-layer,Studied the noise characteristics of GPS signals.It has certain reference value to weaken the impact of a variety of GPS noise.
