The realization of this real-time system can develop the market of PPP and it can also do some real-time researches, such as earthquake, etc. In addition, multi-GNSS can increase the number of satellites and also good constellation geometries. Therefore, it is beneficial to the positioning performance in terms of availability and reliability. This paper mainly introduces the structure of multi-GNSS real-time precise point positioning service system and the measures about how to build the platform. And it also discusses the differences between real-time PPP and post-processing PPP, and the differences between single-system and dual-system PPP. Certainly, it also briefly introduces the theories and methods of real-time satellite clock error and PPP computations. The experiments are carried out and the positioning achievement is analyzed. Based on the experimental results, the positioning precision and the convergence efficiency of dual-system are better than the GPS-only system. All 3D components of positions can reach centimeter-level accuracy.","PeriodicalId":340067,"journal":{"name":"2017 Forum on Cooperative Positioning and Service (CPGPS）","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127907544","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}

The high-rate GPS clock corrections are required in the applications of geosciences with a high sampling rate (up to 5Hz). Therefore, the high-rate precise clock corrections of achieving high accuracy positioning resolution are in demand. Normally, the undifferenced phase and range observations are utilized to estimate satellite clock corrections with a global network. However, the processing is time-consuming and cumbersome due to a large number of parameters. For example, ambiguities are estimated together with clock corrections parameters. To achieve a trade-off between the high accuracy and the efficiency, the quality of linearly interpolated GPS clock corrections with different sample rates demands further investigation. We assessed the performance of the linearly interpolated GPS clock corrections with different sample rates and applied them into positioning. The results show that the difference of the positioning accuracy is below 1% for 2s, 5s, and 10s clock corrections and a slightly larger for 15s clock corrections, around 2%. However, the positioning accuracy can be improved by about 13% using the 1s sampling rate by comparing with the 30 s sampling rate.","PeriodicalId":340067,"journal":{"name":"2017 Forum on Cooperative Positioning and Service (CPGPS）","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122523582","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}
