The robot platform uses a sensor fusion approach with Global Navigation Satellite System (GNSS), odometers, inertial and range sensors in order to obtain a position and heading solution with the required precision to navigate inside the greenhouse and to localize accurately the pests. Previously some tests were carried out inside a greenhouse to verify its localization subsystem performance, but due to the difficulties to get a reliable ground truth, additional tests in open sky conditions has been done. As there are some circumstances than can degrade the GNSS signals, especially in a harsh environment like a greenhouse, an adaptive configuration of the Augmented Monte Carlo Localization (AMCL) based in GNSS quality indicators is proposed. The open sky data collected has been used to check the behavior of the proposed approach simulating gaps in the GNSS signals and the results show that this localization subsystem can deal with these outages maintaining the position solution close to the system specifications.","PeriodicalId":157951,"journal":{"name":"2020 European Navigation Conference (ENC)","volume":"538 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123245825","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}

To meet the challenges of the 21st century in the field of road transport, simulation platforms are receiving increasing attention, in an attempt to advance intelligent transportation system (ITS) optimization. Although a plethora of simulation platforms for intelligent transportation systems exist, formalism have not yet been reported that ensure reliable data exchange among different ITS simulation platforms. This paper presents a conceptual model serving as a formal basis for designing ITS simulation platforms for roads based on building information modeling (BIM), which is a method mandated in many European countries when designing and building public infrastructure. In this paper, an extension of the current BIM standard, the Industry Foundation Classes (IFC) schema, is proposed, enabling standard-compliant, BIM-based simulation of intelligent transportation systems for roads. First, the conceptual model is presented, serving as a basis for the IFC schema extension. Then, the IFC schema extension is described and verified with the test software of the official IFC certification program. Next, an illustrative BIM-based simulation scenario is presented for validating the IFC schema extension. The paper concludes with a summary and an outlook on potential future research.","PeriodicalId":157951,"journal":{"name":"2020 European Navigation Conference (ENC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114651795","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 approach is applicable to situations when not all the GNSS observables are accompanied with DGNSS corrections. A commonly used “classical” recommendation for such cases is to discard observables which do not have corrections. However, in challenging conditions like urban canyon this recommendation might lead to a case, when such “correct” DGNSS solution might be of poorer quality than the stand-alone one. This is especially true for SBAS, as all operating systems broadcast GPS-only corrections, while user receiver might be capable of tracking signals of GLONASS, Beidou, GALILEO, NavIC in addition to GPS. The suggested in the paper approach is based on rather straightforward methodology, according to which all observables are divided by groups, depending on GNSS type and correction data availability. In the process of computing the position several new unknowns are introduced - one for every group, to estimate clock offsets associated with every group. This approach is implemented in the newest firmware of Topcon receiver boards, which is going to be released soon. The paper provides positioning algorithm's description and results, demonstrating benefits of the suggested approach over the “classical” one. In addition, a paper touches a problem of necessity to revise a definition of “DGNSS mode”, as today there is no term for designating a solution, computed with a mixture of corrected and uncorrected observables.","PeriodicalId":157951,"journal":{"name":"2020 European Navigation Conference (ENC)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624216","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}
