The aim of the study is to perform the analysis of navigational safety in vicinity of newly constructed quay placed to the east of the island Ostrow Brdowski. The Quay is intended handling of large steel structures. The Fast-Time simulation is performed to evaluate the safety of the navigation passage through the fairway along the quay for the future use of vessels which length may exceed 260 m. This kind of simulation method has been implemented to make a statistical analysis based on a large amount of data, the collection of which would be very expensive and time consuming using a Real-Time simulator.","PeriodicalId":30601,"journal":{"name":"Annual of Navigation","volume":"25 1","pages":"108 - 93"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48234984","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 first network is the EUREF Permanent Network (EPN), the second is EPN subnetwork processed by WUT LAC (WUT), the third is exactly Ukraine reference network (URN). The position differences between these networks - EPN and URN (WUT and URN) can reach 9.1 (6.6) mm for X, 4 (3.8) mm for Y and 11.7 (12.2) mm for Z. To obtain consistent station positions and velocities without network effect two weekly solutions were combined. The results demonstrate that the network effect on the local solution (Ukraine reference network) can be eliminated. This approach is valid because the same data analysis strategy was applied during both network processing.","PeriodicalId":30601,"journal":{"name":"Annual of Navigation","volume":"25 1","pages":"155 - 164"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44093393","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}

This applies also to navigation, where the most commonly waves have lengths measured in centimetres (radar, GPS) and longer, such as the waves used in the AIS or DGPS technologies. Navigators are mostly interested in the communication functionality of the used systems, i.e. such factors as range of the system and signal-to-noise ratio. This leads directly to increasing the transmitters’ power. However, it is important to bear in mind that the electromagnetic field can endanger human health, therefore, establishing the level of radiation both on vessels and near the shore transmitters is crucial in this context. The experience of authors shows that the knowledge of the most of navigators hereupon is not large. From this result extremely irresponsible behaviors of one persons, as well as inexplicable phobias others. This article presents the subject using the example of the electromagnetic field present near a lighthouse emitting AIS and DGPS signals. Relevant measurements were made at the Rozewie lighthouse by certified laboratory of Maritime Institute in Gdansk according the polish standards and internal, certified procedures. Results of the measurements were related to the national and European standards for electromagnetic field measurements in the context of occupational health and safety.","PeriodicalId":30601,"journal":{"name":"Annual of Navigation","volume":"25 1","pages":"109 - 124"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48895639","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}

Sánchez, A. González, J. Bruzual","doi":"10.1515/aon-2019-0005","DOIUrl":"https://doi.org/10.1515/aon-2019-0005","url":null,"abstract":"Abstract EDAS (EGNOS Data Access Service) is the EGNOS internet broadcast service, which provides free of charge access to the data collected and generated by the EGNOS infrastructure. EDAS disseminates over the Internet, both in real time and via an FTP archive, the raw data of the GPS, GLONASS (no commitment on GLONASS data is provided (1)) and EGNOS GEO satellites collected by the receivers located at the EGNOS reference stations, which are mainly distributed over Europe and North Africa. The EDAS services offer several types of GNSS data in various protocols and formats, such as DGNSS corrections. This paper reports on the results of some in-field tests conducted by ESSP and Topcon Agriculture to confirm the suitability of EDAS DGNSS corrections for precision farming in Europe. The European Commission (EC) is the owner of EGNOS system (including EDAS) and has delegated the exploitation of EGNOS to the European GNSS Agency (GSA). EDAS service provision is performed by ESSP, as EGNOS Services Provider, under contract with the GSA, the EGNOS program manager. In the ENC 2018 article “EDAS (EGNOS Data Access Service): Differential GPS corrections performance test with state-of-the-art precision agriculture system”, ESSP and Topcon Agriculture presented the results of the first in-field test conducted in a dynamic and real-life environment in the summer of 2017. The test results indicated that the EDAS DGNSS corrections could enable a reliable pass-to-pass accuracy performance for a wide range of precision agriculture applications and become an attractive solution for cereal farms, when the farm is located in the vicinity of an EGNOS reference station. In particular, Topcon Agriculture acknowledged that the observed performance was sufficient to support the following precision agriculture applications: spraying and spreading of any crop type, tilling and harvesting of cereal. Then, ESSP and Topcon Agriculture engaged in additional testing activities to further characterise the EDAS DGPS performance in different scenarios (i.e. at various European locations and with a variety of distances between the designated farm and the target EGNOS reference station). In each test, multiple runs with the rover tractors have been performed over the reference patterns predefined in the Topcon guidance systems. Data recorded during the tests has been analysed in detail, looking at the key performance indicators (e.g. cross track error and pass-to-pass performance) that characterize the EDAS DGPS performance for precision agriculture applications. Different techniques for the computation of the pass-to-pass accuracy performance have been used, including a procedure to measure live in the field and a post-processing alternative. The diversity of scenarios available allows drawing conclusions on the applicability of EDAS DGPS corrections (in terms of maximum distance from the target EGNOS station) for precision agriculture and also understanding the impact of operati","PeriodicalId":30601,"journal":{"name":"Annual of Navigation","volume":"26 1","pages":"46 - 58"},"PeriodicalIF":0.0,"publicationDate":"2018-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47448812","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}

UWB outages may occur due to non-line-of-sight between the UWB radios. To mitigate the errors during short UWB outages, we consider the special dynamics of the platform by adaptively applying constraints in the navigation filter. The application presented here is the navigation problem of the unexploded ordnances (UXOs) mapping platform. A UXO platform moves straight or performs turns or stops; these are the three dynamic states with pre-defined constraints. Two neural networks are examined to determine the current dynamic state based on IMU data. Tests on open-sky and canopied areas were carried out for the performance assessment. The networks were trained on the open-sky dataset, and then tested on the canopied area. The detected improvement of the proposed solution is 10–30% (10–15 cm) for 5–10 s long outages.","PeriodicalId":30601,"journal":{"name":"Annual of Navigation","volume":"65 1","pages":"247-261"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/NAVI.227","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42961381","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}
