摘要
随着多行业应用规模的扩大以及智能化服务需求的不断增加,基于CORS的卫星导航位置服务应用也越来越广泛,其中GNSS基准站卫星数据质量的优劣直接影响到卫星导航位置服务的效果。该文使用TEQC和RTKPLOT软件对基准站卫星数据的完整性、多路径、周跳等数据质量进行分析后,采用基于经验模态分解的小波变换对数据质量进行处理。实验证明,经过处理后的数据,数据质量得到了提升,可为定位服务提供可靠的质量保证。
With the expansion of multi industry application scale and the increasing demand for intelligent services,the application of satellite navigation position service based on CORS is becoming more and more extensive.The quality of GNSS reference station satellite data directly affects the effectiveness of satellite navigation position service.In this paper,the TEQC and RTKPLOT softwares are used to analyze the integrity,multipath,cycle slip and other data quality of reference station satellite data.The wavelet transform based on empirical mode decomposition is used to process the data quality.The experiment proves that the data quality is improved after processing,which can provide reliable quality assurance for location services.
