1 DANUBE INFORMATION SERVICES CONFERENCE- DISC 2016 Regenburg, Germany 6-7 th of December 2016 GEURIW project- use of EGNOS for inland waterways navigation Alina Radutu- Romanian Space Agency romanian space agency agenţia spaţială română Institute of Space Science

2 Overview Introduction Objectives and activities EGNOS Fluvial and maritime regulations and standards research Data collection campaign Data processing campaign Conclusions

3 Introduction EGNOS European SBAS EGNOS V2 - SoL service for civil aviation applications EGNOS V3 Commission Implementing Decision - specifications for the maritime SoL service Inland waterway navigation Currently established GPS augmentation method - Differential GPS (DGPS) EGNOS and DGPS - similar performances EGNOS - convenient solution to complement the existing DGPS infrastructure GEURIW project GNSS environment and user requirements characterization on the Danube River Funded under the European GNSS Evolution Programme (EGEP) of ESA Started nov Consortium Romanian Space Agency Research Center (ROSA-RC) Institute of Space Sciences (ISS), Romania

4 Objectives and activities Main Objective A detailed assessment of both EGNOS and DGPS performance Identify different complementing options for inland waterway navigation Activities Fluvial and maritime regulations and standards research Data collection campaign on the Romanian Danube Sector Two vessels Different landforms Different navigation phases

5 EGNOS RIMSs sites

6 EGNOS Availability Performance- Romania- border of EGNOS availability APV-I HPL < 40 m VPL < 50 m

7 Fluvial and maritime regulations and standards research Context Lack of harmonization at European level of rules and regulations governing the navigation on different rivers Special focus on the operational requirements for ship positioning Involvement of the Romanian maritime and fluvial authorities: Romanian Naval Authority (RNA) Lower Danube River Administration, Giurgiu

8 Fluvial and maritime regulations and standards research Rules and regulations on positioning systems and equipment At system level IMO resolution A.1046(27) focus on World Wide Radio Navigation System (WWRNS) operational requirements for a generic component of the system GNSS- included, together with an augmentation system- most critical operations ITU-R M need for augmentation Augmentation systems- DGNSS and SBAS Advantages of SBAS towards DGNSS Augmentation over a much larger area Service provided to an unlimited number of ships No additional terrestrial infrastructure

9 Fluvial and maritime regulations and standards research Position of the Romanian fluvial and naval authorities concerning the use of EGNOS as augmentation system Use of SBAS as augmentation system- no possibility of any control on the system (as for DGPS) RNA and LDRA focused on the user needs RNA The mission of RNA- to create the best possible traffic conditions for the economic operators (safety and efficiency) If EGNOS offers better performances in terms of positioning with lower costs for the economic operators- RNA will sustain this kind of system, whether the authority has or has not the control of the system. LDRA: beside the lower cost for the operators, the augmentation system should have the possibility to be easily integrated in the RIS services in order not to add new tasks to the ship-master

10 Data collection campaign Two different vessels with different dimensions- highlight any possible differences in the multipath error models First campaign DONARIS 3 hydrographic survey ship

11 Data collection campaign First campaign 28 th -31 st of March km navigated distance

12 Data collection campaign First campaign Characterization of the fluvial environment in five typical navigation phases: flat (or regular ) navigation; canyon navigation; port navigation; navigation under the bridges; and water lock navigation.

13 Data collection campaign First campaign Flat (or regular ) navigation Plain Area and holm downstream Moldova Veche port Google Earth

14 Data collection campaign First campaign Canyon navigation

15 Data collection campaign First campaign Port navigation Drobeta Turnu Severin port

16 Data collection campaign First campaign Navigation under the bridge Donaris 3 boat approaching Calafat bridge

17 Data collection campaign First campaign Waterlock navigation Donaris 3 boat in water lock (Iron Gates I)

18 Data collection campaign First campaign Receiver Antenna AsteRx-U UHF Marine PolaNt-x MF antenna System architecture

19 Data collection campaign First campaign

20 Data collection campaign Second campaign SEMNAL 2 Signalling River Ship July 2016 Upstream of Giurgiu Two AsteRx-U UHF receivers

21 Data Processing Campaign 2D Error distribution for GPS-L1 positioning

22 Data Processing Campaign Small ship multipath model Single multipath model recommended for all navigation phases Large ship multipath model

23 Data Processing Campaign Small ship static multipath Large ship static multipath Structural elements of the ships don t have a specific impact over the multipath

24 Data Processing Campaign Multipath exponential models comparison

25 Conclusions GEURIW project Benefits and liabilities of using SBAS system highlighted EGNOS is already providing positioning results compatible with current IMO recommendations and is suitable for complementing DGPS A preliminary multipath model for the inland waterway environment is made Further investigations- needed to confirm and/or improve this model
