Autonomous or semi-autonomous navigation requires a positioning solution of high accuracy and robustness. By introducing the new European Galileo satellite system, multi-constellation with GPS offers new opportunities of accuracy and integrity enhancements. Although, the Galileo system is still in buildup phase, Galileo test environments (GATEs) allow testing Galileo applications. The present publication shows the extension of an existing GNSS-aided sensor integration filter, enabling the GATE applicability. Focus is put on the particular localization conditions in terms of geometrical constellation of ranging sources. A GNSS-only snapshot algorithm is considered making use of a 2D approach. Extensive sensitivity analysis shows robustness of this approach, even with a minimum set of available ranging sources of unfavourable geometrical constellation. Afterwards this 2D approach is carried towards the tightly-coupled filtering of GNSS observables and Inertial Measurement Unit (IMU). Testing and Validation is performed at automotiveGATE, which is part of an automotive test track near Aachen. Even without any pseudo-range corrections the results of the filter algorithm show 2D average positioning errors less than 0.7 m in areas of geometrical constellation with acceptable horizontal and high vertical Dilution of Precision (DOP).","PeriodicalId":145124,"journal":{"name":"2017 European Navigation Conference (ENC)","volume":"1 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":"130134579","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}

GPS signals are right hand circularly polarized (RHCP) however, in dense multipath environments the polarization of a GPS signal may change to become left hand circularly polarized (LHCP). Conventional GPS receivers use RHCP antenna, which reject LHCP signals, and parallel searching acquisition methods that are not sensitive to the resulting weak signals. In vehicular communications, urban environments is a source multipath and weak signals that can lead to GPS lock loss, but obtaining consistent positioning information in urban environments is crucial for vehicular communication. In this paper, we propose a very low-cost dual polarization patch antenna for LHCP GPS signals, but due to the weak signal strength from reflected signals we also propose a modified serial searching acquisition method using a software-based GPS receiver. The experimental results show that using this method we were able to acquire additional satellites that could be used to compensate for the loss of RHCP signals in multipath environments.","PeriodicalId":145124,"journal":{"name":"2017 European Navigation Conference (ENC)","volume":"17 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":"130960792","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}
