A simplified two-dimensional INS is considered using measurement information from either scalar or vector measurements of the Earth’s magnetic field. The measurement update is developed from existing global magnetic field models in the regions of interest. Cramer-Rao lower bound (CRLB) analysis is performed for this simplified system for two common marine vessel operating modes, transit between ports and localized operations.","PeriodicalId":201935,"journal":{"name":"Proceedings of the ION 2019 Pacific PNT Meeting","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123941710","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 proposed method is based on a low cost physical game engine developed by Rockstar Games, Inc. that is commercially available in the market, thereby cost-effectively available to individuals. In order to implement the ADAS and AD simulator, we present first how to obtain internal data from the game engine and further how to generate useful data for the use of development of ADAS and AD algorithms, e.g. training dataset for deep learning algorithms. In addition, we present a method to generate the simulated sensor data by modeling the actual sensors based on acquired Ground Truth (GT) data. An example of the simulation environment setting through the GUI is presented, and the entire structure of the simulator configuration is also presented.","PeriodicalId":201935,"journal":{"name":"Proceedings of the ION 2019 Pacific PNT Meeting","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121218515","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}

NLOS Detection and Compensation using a Vector Tracking-based GPS Software Receiver 基于矢量跟踪的GPS软件接收机NLOS检测与补偿

{"title":"NLOS Detection and Compensation using a Vector Tracking-based GPS Software Receiver","authors":"Bing Xu, L. Hsu","doi":"10.33012/2019.16777","DOIUrl":"https://doi.org/10.33012/2019.16777","url":null,"abstract":"Accurate positioning is highly desirable in urban canyons where satellite signals are easily reflected or blocked by buildings, leading to severe multipath effects or non-light-of-sight (NLOS) receptions. Anti-multipath techniques, e.g., careful antenna or correlator designs, however, have little improvement for NLOS reception. Existing NLOS detection techniques, e.g., the usage of dual- polarization antenna, or fish-eye camera, require external aiding, which is not suitable for low-cost global positioning system (GPS) receivers, e.g., smartphones or wearable devices. In this paper, we use features, such as multi-correlator or code discriminator outputs, extracted at the signal tracking level, to detect NLOS reception in a vector tracking-based software receiver. Multiple correlators with small spacings also help to find the NLOS path delay, which will be further compensated for updating the extended Kalman filter for positioning. Experimental results using real GPS signals in an urban area in Hong Kong show that the proposed method is capable of detecting the NLOS reception and preventing the positioning error from increasing during the NLOS reception period. By comparison, conventional tracking loops would lock onto the incoming NLOS signal and cannot detect its existence, thus reporting an increased positioning error.","PeriodicalId":201935,"journal":{"name":"Proceedings of the ION 2019 Pacific PNT Meeting","volume":"91 13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126037259","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}
