摘要
随着北斗卫星导航系统的发展,北斗卫星数据在许多领域得到广泛应用,对北斗数据质量的监测变得越来越重要。文中在Visual Studio 2008开发平台下基于C++语言,设计并实现北斗数据质量分析软件,分析软件具有分析观测数据中多路径误差、周跳、载噪比、数据可用率和电离层延迟等信息的功能。利用开阔环境、树林环境、玻璃幕墙环境中的观测数据对分析软件进行测试,结果表明,分析软件能够真实反映出观测数据的质量情况。
With the development of Beidou satellite navigation system,Beidou satellite data have been widely used in many fields.Therefore,it is becoming increasingly important to monitor the data quality of Beidou.Because of this,a Beidou data quality analysis software is provided based on C++language in Visual Studio 2008 development platform.The software can be used to analyze the multipath effects,cycle-slip,carrier-to-noise density ratio,data availability and ionospheric delay which are contained in the observation data.The test results of this software with the observation data collected under open sky,the trees and nearby aglass wall indicate that the Beidou data quality analysis software can really reflect the quality of Beidou observational data.
