| 摘 要： | 通过提取南宁实验GPS控制网的原始载波信号,利用小波分析理论在多尺度、多分辨率、可伸缩、可平移等分析方面的优势,分别对提取的原始载波信号、单差观测值、双差观测值采用bd3小波函数进行3层小波分解,研究各种GPS信号噪声的特性,对减弱各种GPS噪声的影响有一定的参考价值。

| Abstract: | 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 GP... |
