摘要
通过提取南宁实验GPS控制网的原始载波信号、单差观测量、双差观测量并分别采用bd3小波函数进行3层小波分解,经分析得出接收机噪声、多路径效应等噪声的影响规律,对GPS数据粗差探测及数据质量评价有一定的参考价值。
The extracted original carrier signal,single-difference measurements and double difference measurements of Nanning experimental GPS control network are processed three layer wavelet decomposition separately by using bd3 wavelet function,the impact law of noise can be obtained such as receiver noise,multi-path effects etc,it has a certain reference value of GPS data on gross error detection and evaluation of data quality.
