9 EGNOS correction transmission via IALA beacons and 12 Dec /28 EGNOS for IWW navigation EGNOS is Europe's regional satellite-based augmentation system (SBAS) that is used to improve the performance of GPS. It provides safety of life navigation services to aviation, maritime and land-based users over most of Europe. It s there, use it EGNOS corrections are broadcast by GEO satellites and are also provided via the Internet (EDAS). EGNOS services are openly available and provided free of charge. EGNOS is owned by the European Commission, who delegated the exploitation of EGNOS to the European GNSS Agency (GSA). GSA aims at fostering the adoption of EGNOS in maritime and inland waterway navigation with the following actions: 1. Use of EGNOS over existing radionavigation infrastructure 2. Direct use of EGNOS SiS by maritime receivers GSA/OP/07/13/SC24

10 Operational benefits of EGNOS Cost efficiency (CAPEX and OPEX) Reduction of onsite infrastructure Reduction of maintenance costs (fewer spares and effort to repair) A centralised EGNOS solution could increase synergies between IALA and systems, since the central server could generate corrections for both systems in an efficient way Transparent for end users and compatible with deployed user equipment EGNOS-VRS corrections via RTCM 2.3 for maritime and #17 for IWW Robustness against RF interferences Quality of EGNOS corrections not affected by local issues that could impact the radiobeacon / base station site (e.g. multipath, jamming, spoofing) Robustness against failures EGNOS SiS and EDAS A traditional DGNSS solution combined with EGNOS ensures redundancy of data to generate corrections and maximises system availability and continuity Improved accuracy Generation of individual EGNOS-VRS corrections for each transmission site Enhanced integrity at system level EGNOS integrity check + DGNSS integrity check Tamás Horváth EGNOS correction transmission via IALA beacons and 12 Dec /28

11 Further considerations In centralised architectures reliable communication lines are a must. Backup communication lines Local backup solution (Alberding BeaconSiteControl SW) Tamás Horváth EGNOS correction transmission via IALA beacons and 12 Dec /28

12 EGNOS correction transmission via IALA beacons and 12 Dec /28 SC24 project goals The project aims at demonstrating that EGNOS can provide multiple benefits to the maritime and IWW service providers. Address technical, operational, economical and liability aspects of using EGNOS as a source for DGNSS correction services. Provide guidelines on EGNOS-based DGNSS correction transmission via for inland waterways, coastal waters and ports, as well as via IALA beacons for coastal waters. Demonstrate the operational performance of EGNOS correction transmission over the existing radionavigation infrastructure ( base stations and IALA beacons). Provide a detailed cost-benefit analysis of DGNSS network optimisation using EGNOS.

27 EGNOS correction transmission via IALA beacons and 12 Dec /28 SC24 preliminary conclusions A Pilot projects demonstrated that EGNOS based differential corrections enable compliance with the applicable maritime and inland waterways navigation requirements defined by IALA/IMO. B CBA results indicate that introducing EGNOS based solutions (complementing/replacing traditional IALA beacon/ station networks) can be a cost effective alternative in adequate operational scenarios. C Interest from several European maritime/inland waterways authorities on EGNOS based solutions over IALA/ confirmed within the project. 4 Pilot Projects in Spain, Germany, Hungary and Latvia ongoing.
