In terms of safety, the European Geostationary Navigation Overlay System (EGNOS) is providing vertical and lateral guidance to civil aviation since 2011. Furthermore, EGNOS can support applications in other sectors such as maritime, railways and road. The present contribution aims to assess the use of EGNOS for maritime navigation compliant with the International Maritime Organization (IMO) requirements established in its Resolution A.1046 (27) for harbour entrances, harbour approaches and coastal waters: 99.8% of Signal Availability, 99.8% of Service Availability, 99.97% of Service Continuity and 10 m of Horizontal Accuracy. The study has selected the waters surrounding the Canary Islands, within the south west border of coverage of EGNOS, to perform a kinematic test campaign from 7th November 2018 to 21st April 2019. For this purpose, we installed a geodetic multi-frequency multi-constellation receiver-antenna pair on-board two vessels from the Armed Institute of the Spanish Civil Guard based in Tenerife. The ESA/UPC GNSS laboratory (gLAB) tool suite has processed the remotely-retrieved GNSS measurements, in conjunction with EGNOS corrections and with cleansed GPS broadcast navigation messages. EGNOS Availability and Continuity have been evaluated within the area comprised between longitudes 13oW to 19oW and latitudes 27oN to 30oN with spatial resolution of 0.1o per 0.1o. The vessel accuracy is evaluated as the difference of coordinates obtained with single-frequency EGNOS solution and the reference trajectory computed with dual-frequency Precise Point Positioning and final orbits from the International GNSS Service. The EGNOS Maritime Service met all IMO requirements in the geographic area of latitudes northern than 28oN and longitudes eastern than 16oW after reaching a Signal Availability of 99.999%, a Service Availability in 99.90% of the predefined rectangular region, and 1.06 m of Horizontal Accuracy at the 95th percentile. In contrast, the Service Continuity requirement (only required for coastal waters) was met in 62.50% of the predefined region. We conclude that the continuity risk is the most limiting factor for expanding the EGNOS Maritime Service along the coastal waters of Canary Islands, in the EGNOS south-west border of coverage.","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124073035","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}

In order to obtain an optimal and reliable position estimate using GNSS, it is necessary to have an accurate model of the pseudorange and pseudorange-rate error terms’ distributions. Previous research contributions addressed the statistical characterization of the pseudorange measurements’ multipath and noise error components in an urban environment by proposing a methodology to isolate the multipath error and the thermal noise component from the pseudorange measurement. The proposed methodology was adapted to include dual constellation measurements in the L1 band, GPS L1 C/A and Galileo E1 OS signal measurements. Moreover, a reliable classification of the signal reception conditions, Lion-of-Sight (LOS) and Non LOS (NLOS), was addressed.\u0000The work conducted in this article consists first in further adaptingthe methodology proposed in the previous work to the pseduorange rate (Doppler frequency) measurement and second, in inspecting the benefits of the derived pseudorange and pseudorange-rate measurements’ error component characterizations when applied on the PVT navigation solution. Finally, the analysis of the PVT estimation performance based on satellite measurement selection principle is presented.","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121384322","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 availability of more GNSSs with modernized signals has revolutionized both the receiver manufacturing and technology industries as well as positioning algorithms. This progression opens the door to a vast number of potential applications including but not limited to location-based services, autonomous navigation, Internet-of-Things (IoT), etc. The user interest in such applications stems out of the point that it would not require geodetic-grade receivers for better position solutions. It would be equally possible to use low-cost receivers to obtain relatively equivalent results, as compared to their geodetic grade counterparts. Though it possible to obtain centimetre level of accuracy using high end geodetic grade receivers, the cost of them poses a challenge. The recent market releases of state-of-the-art low-cost receivers capable of tracking multiGNSS signals offers a glimpse into the potential level of improvement in the user solution accuracy. This paper investigates various low-cost, multi-GNSS receiver chipsets, including: Piksi Multi Module, Unicorecomm Nebulas II, Septentrio Mosaic, and Ublox F9 sensors. It is important to note that the idea of investigating these receiver modules is not to either advocate for or promote these brands. This paper aims to address how the accuracy of low-cost receivers have improved over the years from the hardware perspective, as well as show how that reflects in the position domain.","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"224 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129224137","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}
