However, when the receiver is orbiting above the GNSS constellation's altitude, designing an on-board, real-time, autonomous GNSS navigation device poses stringent requirements. Indeed, in such a challenging operational environment, the signal availability as well as the ranging error can be significantly influenced by the selection of the signals and their processing. In this paper, we define different tracking strategies which provide or not an ionosphere-free combination; for all altitudes or only for some altitudes; and for all the signals or for only those crossing the ionosphere. Then, we evaluate their effects on the signals availability; on the relative geometry between the receiver and the transmitters; and on the ranging error, in order to finally identify the best strategy. The analysis is performed for a GPS L1/L5 spaceborne receiver currently under development in our laboratory, specifically conceived for GNSS-based navigation from the Earth to the Moon.","PeriodicalId":145124,"journal":{"name":"2017 European Navigation Conference (ENC)","volume":"461 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":"134179265","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}

Ahamad, Ahmad Farhan Mohd Sadullah","doi":"10.1109/EURONAV.2017.7954195","DOIUrl":"https://doi.org/10.1109/EURONAV.2017.7954195","url":null,"abstract":"Transit services or public transportation is expected to be able to not only provide a good mobility and accessibility to people in a city, but it should allow a pleasant journey to them to attract people to ride it. It can be influenced by the presence of built environments such as the pedestrian facilities and furniture along the walking route. Therefore, many studies have attempted to measure the attractiveness of the first/last mile (FLM) transit journey, however, there seem to be limitations in those studies. First, there is a lack of pedestrian data available. This could affect the precision of measuring the pedestrian attractiveness. Second, there is a lack of studies implementing such data to analyze the pedestrian-attractiveness itself. This paper proposes a framework combining spatial data collection for pedestrian data with spatial analysis to measure the pedestrian-attractiveness of the FLM transit journey. It will utilize the mobile positioning procedure to collect the data as it is the most efficient method to collect thousands of pedestrian data on the ground in a short amount of time. It uses a mobile mapping application available on the market to collect data in the field. The collected spatial data will then be used as attributes in the spatial analysis of the pedestrian routes of the FLM transit journey. The outcome of the framework will be a score indicating the pedestrian-attractiveness of the FLM transit journey. The results show that the pedestrian-attractiveness score can be influenced by the number of built environments present along the walking route and public preferences of these. A station with a higher number of built environments will score more than the other. Similarly, a station with a more preferred parameters will also score higher.","PeriodicalId":145124,"journal":{"name":"2017 European Navigation Conference (ENC)","volume":"101 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":"132784875","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}

Additionally, it has become one of the biggest challenges for the Safety-of-Life (SoL) services in railway transport systems using GNSS techniques. The critical performance requirements of these services promote the users to develop safe Train Positioning Systems (TPSs), in which integrity has to be highly concerned to real-timely monitor the quality of the TPS results. This paper presents a solution to the problem of integrity monitoring in GNSS-based train positioning with a global prospect. Different from the RAIM (Receiver Autonomous Integrity Monitoring) approach, a novel hierarchical architecture is proposed to expand the RAIM concept to the TPSAIM (Train Positioning System Autonomous Integrity Monitoring) domain, where integrity monitoring is closely correlated with both GNSS navigation computation at the local level and sensor integration at the global level. Integrity monitoring and fault detection with respect to the integration of GNSS and the Dead Reckoning (DR), which can be simply implemented with odometer and gyroscope, are investigated with different coupling structures. Results from simulations based on the field experiment illustrate characters of the proposed TPSAIM solution, and demonstrate its capabilities in terms of the effectiveness, coverage and flexibility with various TPS structures and operation conditions.","PeriodicalId":145124,"journal":{"name":"2017 European Navigation Conference (ENC)","volume":"26 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":"132153667","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}
