This error depends on the error of determining the pseudorange and on the geometric factor value. The altitude of the sonde is the most important of all the measured coordinates. In this study, we analyzed the accuracy of measuring the aerologic sonde altitude by means of GLONASS inbuilt tools within the territory of the Russian Federation. We also analyzed how to implement the measurement differential mode in the system of aerological observation of atmosphere and showed the efficiency of the use of a pseudo-satellite in order to improve the accuracy of measuring the sonde position. The use of the differential mode decreases the pseudorange measurement error by several times, which fact results in the decrease of the error of the aerologic sonde altitude measurement. The use of pseudo-satellites allows decreasing the geometric factor value and improving the accuracy of the sonde position measurement. The most obvious solution is to install the pseudo-satellite on the position of the aerological station. In this study, we analyzed the efficiency of this solution.","PeriodicalId":108493,"journal":{"name":"2019 26th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123933024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work we analyse a low-cost INS for using in the vehicle navigation equipment. An INS/GNSS/odometer integration algorithm was developed and applied to postprocessing data collected from a typical testing survey. The computed integrated navigation solution was compared with a reference solution provided by a NovAtel navigation system. The reference navigation system consisted of a tactic-grade strapdown INS, an odometer and two high precision GNSS receivers operating in the differential mode. Numerical results presented in the paper show that the low-cost INS/GNSS/odometer integration allows to determine the vehicle position in an urban area with an accuracy of 1 m and the roll and pitch angles with an accuracy of 0.1° that satisfy accuracy requirements.","PeriodicalId":108493,"journal":{"name":"2019 26th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122371528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
